Optical safety

For a detailed description about Optical safety guidelines, refer theMetropolis® AMUSafety Guide.

IEC Customer Laser Safety Guidelines

Lucent Technologies declares that this product is compliant with all essential safetyrequirements as stated in IEC 60825-Part 1 and 2 “Safety of Laser Products” and“Safety of Optical Fibre Telecommunication Systems”. Futhermore, LucentTechnologies declares that the warning statements on equipment labels are inaccordance with the specified laser radiation class.

Optical Safety Declaration (if laser modules used)

Lucent Technologies declares that this product is compliant with all essential safetyrequirements as stated in IEC 60825-Part 1 and 2 “Safety of Laser Products” and“Safety of Optical Fiber Telecommunication Systems”. Furthermore, LucentTechnologies declares that the warning statements on equipment labels are inaccordance with the specified laser radiation class.

Optical Fiber Communications

This equipment contains an Optical Fiber Communications semiconductor laser/LEDtransmitter. The following Laser Safety Guidelines are provided for this product.

General Laser Information

Optical fiber telecommunication systems, their associated test sets, and similaroperating systems use semiconductor laser transmitters that emit infrared (IR) light atwavelengths between approximately 800 nanometers (nm) and 1600 nm. The emittedlight is above the red end of the visible spectrum, which is normally not visible to thehuman eye. Although the radiant end at near-IR wavelengths is officially designatedinvisible, some people can see the shorter wavelength energy even at power levels thatare several orders of magnitude below any levels that have been shown to cause injuryto the eye.

Conventional lasers can produce an intense beam of monochromatic light. The term“monochromaticity” means a single wavelength output of pure color that may bevisible or invisible to the eye. A conventional laser produces a small-size beam oflight, and because the beam size is small the power density (also called irradiance) isvery high. Consequently, lasers and laser products are subject to federal and applicablestate regulations, as well as international standards, for their safe operation.

A conventional laser beam expands very little over distance, or is said to be very wellcollimated. Thus, conventional laser irradiance remains relatively constant overdistance. However, lasers used in lightwave systems have a large beam divergence,typically 10 to 20 degrees. Here, irradiance obeys the inverse square law (doubling thedistance reduces the irradiance by a factor of 4) and rapidly decreases over distance.

Lasers and Eye Damage

The optical energy emitted by laser and high-radiance LEDs in the 400-1400 nm rangemay cause eye damage if absorbed by the retina. When a beam of light enters the eye,


...................................................................................................................................................................................................................................

xviii Lucent Technologies - ProprietarySee notice on first page

365-312-847R4.0Issue 4, November 2006

,

the eye magnifies and focuses the energy on the retina magnifying the irradiance. Theirradiance of the energy that reaches the retina is approximately 105, or 100,000 timesmore than at the cornea and, if sufficiently intense, may cause a retinal burn.

The damage mechanism at the wavelengths used in an optical fiber telecommunicationsis thermal in origin, i.e., damage caused by heating. Therefore, a specific amount ofenergy is required for a definite time to heat an area of retinal tissue. Damage to theretina occurs only when one looks at the light long enough that the product of theretinal irradiance and the viewing time exceeds the damage threshold. Optical energiesabove 1400 nm cause corneal and skin burns, but do not affect the retina. Thethresholds for injury at wavelengths greater than 1400 nm are significantly higher thanfor wavelengths in the retinal hazard region.

Classification of Lasers

Manufacturers of lasers and laser products in the U.S. are regulated by the Food andDrug Administration’s Center for Devices and Radiological Health (FDA/CDRH) under21 CFR 1040. These regulations require manufacturers to certify each laser or laserproduct as belonging to one of four major Classes: I, II, lla, IlIa, lllb, or IV. TheInternational Electro-technical Commission is an international standards body thatwrites laser safety standards under IEC-60825. Classification schemes are similar withClasses divided into Classes 1, 1M, 2, 2M, 3R, 3B, and 4. Lasers are classifiedaccording to the accessible emission limits and their potential for causing injury.Optical fiber telecommunication systems are generally classified as Class I/1 because,under normal operating conditions, all energized laser transmitting circuit packs areterminated on optical fibers which enclose the laser energy with the fiber sheathforming a protective housing. Also, a protective housing/access panel is typicallyinstalled in front of the laser circuit pack shelves The circuit packs themselves,however, may be FDA/CDRH Class I, IIIb, or IV or IEC Class 1, 1M, 3R, 3B, or 4.

Laser Safety Precautions for Optical Fiber Telecommunication Systems

In its normal operating mode, an optical fiber telecommunication system is totallyenclosed and presents no risk of eye injury. It is a Class I/1 system under the FDA andIEC classifications.

The fiber optic cables that interconnect various components of an optical fibertelecommunication system can disconnect or break, and may expose people to laseremissions. Also, certain measures and maintenance procedures may expose thetechnician to emission from the semiconductor laser during installation and servicing.Unlike more familiar laser devices such as solid-state and gas lasers, the emissionpattern of a semiconductor laser results in a highly divergent beam. In a divergentbeam, the irradiance (power density) decreases rapidly with distance. The greater thedistance, the less energy will enter the eye, and the less potential risk for eye injury.Inadvertently viewing an un-terminated fiber or damaged fiber with the unaided eye atdistances greater than 5 to 6 inches normally will not cause eye injury, provided thepower in the fiber is less than a few milliwatts at the near IR wavelengths and a fewtens of milliwatts at the far IR wavelengths. However, damage may occur if an opticalinstrument such as a microscope, magnifying glass, or eye loupe is used to stare at theenergized fiber end.

CAUTION

Laser hazard

Use of controls, adjustments, and procedures other than those specified herein mayresult in hazardous laser radiation exposure.

Laser Safety Precautions for Enclosed Systems

Under normal operating conditions, optical fiber telecommunication systems arecompletely enclosed; nonetheless, the following precautions shall be observed:

1. Because of the potential for eye damage, technicians should not stare into opticalconnectors or broken fibers

2. Under no circumstance shall laser/fiber optic operations be performed by atechnician before satisfactorily completing an approved training course

3. Since viewing laser emissions directly in excess of Class I/1 limits with an opticalinstrument such as an eye loupe greatly increases the risk of eye damage,appropriate labels must appear in plain view, in close proximity to the optical porton the protective housing/access panel of the terminal equipment.

Laser Safety Precautions for Unenclosed Systems

During service, maintenance, or restoration, an optical fiber telecommunication systemis considered unenclosed. Under these conditions, follow these practices:

1. Only authorized, trained personnel shall be permitted to do service, maintenanceand restoration. Avoid exposing the eye to emissions from un-terminated, energizedoptical connectors at close distances. Laser modules associated with the opticalports of laser circuit packs are typically recessed, which limits the exposuredistance. Optical port shutters, Automatic Power Reduction (APR), andAutomatic Power Shut Down (APSD) are engineering controls that are also used tolimit emissions. However, technicians removing or replacing laser circuit packsshould not stare or look directly into the optical port with optical instruments ormagnifying lenses. (Normal eye wear or indirect viewing instruments such asFind-R-Scopes are not considered magnifying lenses or optical instruments.)

2. Only authorized, trained personnel shall use optical test equipment duringinstallation or servicing since this equipment contains semiconductor lasers (Someexamples of optical test equipment are Optical Time Domain Reflectometers(OTDR’s), Hand-Held Loss Test Sets.)

3. Under no circumstances shall any personnel scan a fiber with an optical test setwithout verifying that all laser sources on the fiber are turned off

4. All unauthorized personnel shall be excluded from the immediate area of theoptical fiber telecommunication systems during installation and service.

Consult ANSI Z136.2, American National Standard for Safe Use of Lasers in the U.S.;or, outside the U.S., IEC-60825, Part 2 for guidance on the safe use of optical fiberoptic communication in the workplace.

Hardware overview of theMetropolis® AMU

Introduction...................................................................................................................................................................................................................................

The Metropolis® AMU is a high capacity, flexible and cost-effective widebandmultiplexer which can multiplex standard PDH and SDH bit rates as well as Ethernetsignals to line transport rates. TheMetropolis® AMU is a compact SDH Multiplexer,enabling cost-effective STM-1, STM-4, and STM-16 Add/Drop Multiplexer solutions.Several mechanical variants are defined to target specific applications. One set ofboards is used across the various mechanical configurations of theMetropolis® AMU.

Its space-efficient design allows for vertical (2m/4o and 1m/1o version) or horizontal(1m/1o version) installation within controlled environment locations (interior ETSI and19” racks). Note that the 2m/4o and 1m/1o versions and all the option cards used inthese versions support hot pluggable card insertion. The 2m/4o configuration allows theplacement of two systems side-by-side in a 19-inch or ETSI rack. The 1m/1oconfiguration allows the placement of up to 5 systems side-by-side. Please refer to theMetropolis® AMU Installation Guidefor details.

2m/4o version

The Metropolis® AMU 2m/4o version has 6 slots (2x main and 4x tributary) and isoptimized for high capacity and protected Central Office applications. The first andsecond main units can be plugged into the two main slots that are provided with a2m/4o configuration. Note that when a single main unit is used, it must be pluggedinto the Main-1 slot. In theMetropolis® AMU 2m/4o configuration, a second maincard can be fitted for high-availability configurations or to increase the capacity forSTM line interfaces. Most of the existingMetropolis® AMU option boards can befitted via an adapter card, which occupies two tributary slots.

Option cards

Introduction...................................................................................................................................................................................................................................

This section describes the option cards which can be used together withMetropolis®

AMU in order to provide interfaces for various data rates or special applications.

PI-E1/63 and PI-E1/63_75 option cards

The PI-E1/63 and PI-E1/63_75 option cards provide 63 times 2 Mbit/s (E1) terminatedon 32 RJ-45 connectors for the use of twisted pair cables (120Ω version) and coaxialcable (75Ω version). It is available in 75Ω and 120Ω versions.

The following figure displays the front panel of the PI-E1/63 option card.

EPL4_E14 option card

Interfaces

On the faceplate the EPL4_E14 card provides:

• Two cages for Small Form-factor Pluggable (SFP) optical transceivers whichsupport 1000Base-X

• Two RJ45 connectors for triple rate Ethernet (10/100/1000Base-T)

Product description

• Two RJ45 connectors for dual rate Ethernet (10/100Base-T)

• Two RJ45 connectors for four E1 interfaces with 75 / 120Ω (Selection can bemade on port level via the user interface; default is 120Ω.)

The EPL4_E14 unit provides 4 ethernet ports. Two of these (5 and 6) support 10/100Base-T line rates while the other two (pairs 7/8 and 9/10) are multirate ports capable of10/100/1000 Base-T/-X. For these ports, the selection between 1000 Base-T (electricalinterfaces 8 and 9) and 1000 Base-X (optical interfaces 7 and 10) has to be done viathe NMS. This selection can be done independently for each Port. When an opticalport is in use, the electrical counterpart is inactive and vice versa. Each connector andeach SFP has its own green LED (data link up: LED ON or down: LED OFF) andyellow LED (transmission: LED ON or no transmission: LED OFF).

The following figure shows the front panel of the EPL4_E14 option card.

The EPL_4_E14 option card is able to compensate a maximum delay difference of 128ms between the fastest and the slowest VC in receive direction.

Link Capacity Adjustment Scheme (LCAS)

The EPL4_E14 option card supports a flexible allocation of SDH bandwidth to LANports by making use of the Link Capacity Adjustment Scheme (LCAS, see“LCAS”(p. 3-22)). All LAN ports have the same capabilities. Each WAN port supportsVC-12-Xv (X = 1...63), VC-3-Xv (X = 1...9), VC-4-Xv (X=1..7).

GFP provides a generic mechanism to adapt traffic from higher-layer client signalsover a transport network. GFP encapsulation is implemented according toT1X1.5/2000-147.

The following GFP encapsulation are possible with EPL4_E14:

• Mapping of Ethernet MAC frames into Lower Order SDH VC12–Xv (X = 1...63)


• Mapping of Ethernet MAC frames into Higher Order SDH VC4–Xv (X=1..7)

LAPS encapsulation is implemented according to ITU-T X.86.

Advanced rate control

The EPL4_E14 option card supports advanced rate control in the ingress and egressdirection which allows to set a strict traffic limit (PIR), in combination with a hold-offmechanism: Excess traffic is held off until the ingress or egress buffer overflows. Incase the ingress buffer fills above a certain threshold, pause messages are sent in thereverse direction to hold off further traffic. This behaviour improves the TCPthroughput. Note that Pause messages can be only sent when the Pause mode isenabled via the Lucent NMS.

Link Pass Through (LPT)

The EPL4_E14 option card supports the Link Pass Through (LPT) mode. Onpoint-to-point Ethernet Private Line connections, when GFP data encapsulation is usedthroughout the network, the system identifies defects from the network ingress port tothe network egress port. The GFP-CSF mechanism is used to notify the egress side thata loss of signal (synchronization) has occurred on the ingress port. Consequently, theegress side can either turn off the laser at the egress (in case of an optical level) orsubstitute an error pattern (for example, a /V/ ordered set for a 1000BASE-X). Inaddition, an alarm is raised at the egress side which indicates the ingress sidecondition. For more information about Link Pass Through, please refer to (LPT, see“LPT” (p. 3-23)). For additional information, please refer the TransLAN® EthernetSDH Transport Solution Applications and Planning Guide.

The EPL4_E14 option card supports Auto MDI/MDIX selection on all LAN ports.

Transmission rates

The following rates are supported with EPL4_E14:

• Mapping Ethernet packets into VC12-Xv (X = 1...63)


• Mapping Ethernet packets into VC4-Xv (X=1..7)

Flexible bandwidth assignment

The transmission capacity of the EPL4_E14 option card towards the cross-connectmatrix is 8 x VC4s. These can be freely assigned to 4 VCGs. There is a fixed 1:1relationship from the 4 Ethernet ports to the 4 VCGs. For an illustrated description, see“EPL4_E14 option card” (p. 2-18).

From the 8 VC-4s, two can be individually substructured to VC-12s to provide upto 2x 63 VC-12s. In this case, the first 4 VC-12s are reserved for the E1 ports. Note thatin case E1 interfaces are used, the first VC-4 needs to be substructured, otherwise, theyare not available. In addition, 3 VC-4s can be individually substructured to VC-3,thereby providing a total of 9 VC-3s.

The remaining 3 VC-4s cannot be substructured. For each of the 4 VCGs, a selectioncan be made between VC-12-Xv (X=1-63), VC-3-Xv (X=1-9), and VC-4-Xv (X=1-7),based on the total number of containers that are available for each type.

The following diagram illustrates the VC/VCG mapping for the EPL4_E14 option card.

Jumbo frame support

The EPL4_E14 option card supports overlength Ethernet frames (also known as Jumboframes) on LAN ports 7, 8, and 9, 10.

EPL4_E132_75 option card

Interfaces

On the faceplate the EPL4_E132_75 board provides:

• Four RJ45 connectors for dual rate Ethernet (10/100Base-T)

• Sixteen RJ45 connectors to cover 32 E1 interfaces with 75Ω only (2x E1 perRJ45)

All four Ethernet RJ45 connectors have their own green and yellow LED whichindicates a LAN connection and traffic flow respectively.

The following figure shows the front panel of the EPL4_E132_75 option card.

overflows. In case the ingress buffer fills above a certain threshold, pause messages aresent in the reverse direction to hold off further traffic. This behaviour improves theTCP throughput. Note that Pause messages are only sent when the Pause mode isenabled via the Lucent NMS.

Auto-negotiation

The EPL4_E132_75 option card supports Auto-negotiation. The Auto-negotiationfunction automatically configures the Ethernet interface parameters to establish anoptimal Ethernet link based on the capabilities of the near-end and far-end Ethernetinterfaces.

Auto-negotiation for twisted-pair systems, defined in Clause 28 of the Standard802.3-2002, has been extended to include all three speeds of Ethernet that aresupported over twisted-pair cable: 10Mbit/s 10Base-T, 100Mbit/s 100Base- TX, and1000 Mbit/s 1000Base-T. For more information about Auto-negotiation support, pleaserefer to the Metropolis® AMU User Operations Guide.

Link Pass Through (LPT)

The EPL4_E132_75 option card supports the Link Pass Through (LPT) mode. Onpoint-to-point Ethernet Private Line connections, when GFP data encapsulation is usedthroughout the network, the system identifies defects from the network ingress port tothe network egress port. The GFP-CSF mechanism is used to notify the egress side thata loss of signal (synchronization) has occurred on the ingress port. An alarm is raisedat the egress side which indicates the ingress side condition. For more information,please refer to (see LPT,“LPT” (p. 3-23)). For additional information, please also referto the TransLAN® Ethernet SDH Transport Solution Applications and Planning Guide.

The EPL4_E132_75 option card supports Auto MDI/MDIX selection on all LAN ports.

Transmission rates

The following rates are supported with EPL4_E132_75:



• Mapping Ethernet packets into VC4-Xv (X=1..7)


The transmission capacity of the EPL4_E132_75 option card towards the cross-connectmatrix is 9 x VC-4s. One VC-4 is reserved for the 32 E1 ports and is not available forthe VCGs. The remaining 8 VC-4s can be freely assigned to 4 VCGs. There is a fixed1:1 relationship from the 4 Ethernet ports to the 4 VCGs. For an illustrated description,see (see fig. on page 2-17).

From the 8 VC-4s, two can be individually substructured to VC-12s, thereby providingupto 2 x 63 VC-12s. In this case, the first 4 VC-12s of the first VC-4 remain unused.

In addition, 3 VC-4s can be individually substructured to VC-3s, providing a total of 9VC-3s. The remaining 3 VC-4s cannot be substructured. For each of the 4 VCGs, a

selection can be made between VC-12-Xv (X=1-63), VC-3-Xv (X=1-9), and VC-4-Xv(X=1-7), based on the total number of containers that are available for each type.

The VC/VCG mapping is shown in the following figure:

Jumbo Frame support

The EPL4_E132_75 option card supports overlength Ethernet frames (also known asJumbo frames) on LAN ports 35 and 36.

ESW4_E14 option card

Interfaces

On the faceplate, the ESW4_E14 card provides:

• Two LAN ports for Small Form-factor Pluggable (SFP) optical transceivers whichsupport 1000Base-X optical SFPs or can be used as 10/100/1000BASE-T electricalports using RJ-45 connectors.

• Two LAN ports for dual rate Ethernet (10/100Base-T) using RJ-45 connectors.

• Two RJ-45 connectors on the faceplate for four E1 interfaces with 75/120Ω(Selection can be made on port level via the user interface; default is 120Ω).

The ESW4_E14 option card provides 4 Ethernet ports. Two of these (5 and 6) support10/100 Base-T line rates, while the other two (pairs 7/8 and 9/10) are multirate andcapable of 10/100/1000 Base-T/-X rates. For these ports, the selection between 1000Base-T (electrical interfaces 8 and 9) and 1000 Base-X (optical interfaces 7 and 10)must be done via the ITM-CIT. This selection can be done independently for each Port.When an optical port is in use, the electrical counterpart is inactive and vice versa.

Each connector and each SFP has its own green LED (data link up: LED ON or down:LED OFF) and yellow LED (transmission: LED ON or no transmission: LED OFF).

The total transmission backplane capacity is 16 x VC-4s. This capacity is onlyavailable in combination with an MI-16/4 main card, provided the ESW4_E14 card isplaced in the first slot (TS1). In any other slot or when combined with the MI-14/4main card, the maximum useable capacity is 10 x VC-4s.

The following figure shows the front panel of the ESW4_E14 option card.

Transmission rates

The following transmission rates are supported with ESW4_E14:





When the ESW4_E14 option card is inserted in tributary slot 1 of a 2m/4o or 1m/1oversion and the main unit is an M1-16/4, the total capacity of the unit is equivalent to16 VC4s (2.5 Gbit/s) with which up to eight VCGs can be created and each VCG canbe assigned to a WAN port. For WAN ports 1 though 4, a capacity of eight VC4s (1through 8) is available. By default, the 1st and 2nd VC4s are substructured in VC12s.Similarly, the 3rd, 4th, and 5th VC4s are substructured as VC3s. Optionally, the 1st to5th VC4s can be changed to unstructured VC4. The 6th, 7th, and 8th VC4s can onlybe used as VC4s. As a result, VC12-Xv (X=1..63), VC3-Xv (X=1..9) and/or VC4-Xv(X=1..7) groups can be created from at most 122 VC12s, 9 VC3s or 8 VC4s.

For WAN ports 5 through 8, a capacity of eight VC4s (9 though 16) is available. Ofthese 8 VC4s, the 9th and 10th VC-4 are substructured in VC12s and the 11th, 12th,and 13th VC4 are substructured in VC3s, by default. Optionally, the 9th to 13th VC4scan be changed to unstructured VC4. The VC4s 14 through 16 can only be used asVC4s. As a result, VC12-Xv (X=1..63), VC3-Xv (X=1..9) and/or VC4-Xv (X=1..7)groups can be created from at most 126 VC12s, 9 VC3s or 8 VC4s.

Note that if the E1 interfaces are used, four VC12s of the first VC4 must be reservedfor E1 transport. In this case, it is mandatory to substructure the first VC4 to carry 63VC12s.

The system automatically detects if the combination of slot number, main unit, andtributary unit allows 16 VC4 backplane capacity. No provisioning is required.

2-23

The ESW4_E14 option card supports overlength Ethernet frames (also known asJumbo frames) on all LAN ports and on WAN ports 3, 4, 7, and 8.

The ESW4_E14 option card can compensate a maximum delay difference of 64 msbetween the fastest and the slowest VC in receive direction.

Enhanced flow classification

The ESW4_E14 option card supports Enhanced Flow Classification - 802.1Q mode and802.1 ad mode. It supports the Flow Control and Pause Frames feature on LAN portsand provides Wire speed performance for forwarding, flooding, address look-up, andflow look-up requirements. The flow classifcation is based on port and priority, portand port, and port and VLAN-ID. The flow classification can be checked on a flexibleset of combinations such as IP_TOS, VLAN-ID, VLAN-UPT, and DA-MAC. The flowbucket can be set to handle 8k to 16k. However, an increased flow bucket size willdecrease performance. The ESW4_E14 option card is IEEE802.1Q/1ad compliant andsupports VLAN and/or ETHER_TYPE switching and adding or removing VLAN tags.

Auto-negotiation

The ESW4_E14 option card supports Auto-negotiation. The Auto-negotiation functionautomatically configures the Ethernet interface parameters to establish an optimalEthernet link based on the capabilities of the near-end and far-end Ethernet interfaces.

Auto-negotiation for twisted-pair systems, defined in Clause 28 of the Standard802.3-2002, has been extended to include all three speeds of Ethernet that aresupported over twisted-pair cable: 10Mbit/s 10Base-T, 100Mbit/s 100Base- TX, and1000 Mbit/s 1000Base-T. For more information about Auto-negotiation, please refer tothe Metropolis® AMU User Operations Guide.


The ESW4_E14 option card supports a flexible allocation of SDH bandwidth to LANports by making use of the Link Capacity Adjustment Scheme (LCAS, see“LCAS”(p. 3-22)). All LAN ports have the same capabilities. Each WAN port supportsVC-12-Xv (X = 1...63), VC-3-Xv (X = 1...9), VC-4-Xv (X = 1...7).

Repeater mode

For units containing Ethernet switches, it is possible to emulate the behaviour of aprivate line port by creating a two-port virtual switch, with one LAN and one WANport and provision it in Repeater Mode. This feature can be implemented in bothEthertype 8100 and Ethertype 9100 mode. In this mode, all traffic from the LAN orWAN side is transparently passed through, except the pause messages. The Pauseprotocol operates on the LAN interface and therefore, transmission without loss can beobtained if the peer node on the LAN link obeys the commands contained in pausemessages.

GFP encapsulation



....................................................................................................................................................................................................................................


365-312-847R4.0Issue 4, November 2006

The following GFP encapsulation are possible with ESW4_E14:

• Mapping Ethernet MAC frames into Lower Order SDH VC12-Xv (X = 1...63)

• Mapping Ethernet MAC frames into Lower Order SDH VC3-Xv (X = 1...21)

• Mapping Ethernet MAC frames into Higher Order SDH VC4-Xv (X = 1...7)



The ESW4_E14 option card supports advanced rate control in the ingress and egressdirection which enables users to set a strict traffic limit (PIR), in combination with ahold-off mechanism: Excess traffic is held off until the ingress or egress bufferoverflows. In case the ingress buffer fills above a certain threshold, pause messages aresent in the reverse direction to hold off further traffic. This behaviour improves theTCP throughput.

Provisioning Committed Burst Size (CBS)

The Flow Profile containing the parameters that define the QoS regime and is appliedto a flow contains a user provisionable entry for the Committed Burst Size (CBS).

This entry describes the number of octets that may be″bursted″ before a frame is nolonger considered part of the″Committed Rate″. The CBS rate can be provisioned inkbytes between 1 and 25000 or as a time constant relative parameter to CIR: 10 or 110ms.

Provisioning Peak Burst Size (PBS)

The Flow Profile containing the parameters that define the QoS regime and is appliedto a flow contains a user provisionable entry for the Peak Burst Size (PBS).

This entry describes the number of octets that may be″bursted″ before a frame is nolonger considered part of the″Peak Rate″. The PBS rate can be provisioned in kbytesbetween 1 and 25000 or as a time constant relative parameter to CIR: 10 or 110 ms.

QoS features

The ESW4_E14 option card supports the following QOS features:

• Two rate three color marker (RFC 2697, RFC 2698, and MEF 10) per flow(switchable color aware/color unaware)Based on provisioned threshold rates (CIR and PIR):

– Red - The frame is dropped

– Yellow - The Dropping Precedence of the frame is set to high

– Green - The Dropping Precedence of the frame is set to low

• Over subscription (2 levels of Dropping Precedence) and strict policing modesBased on queue filling and the Dropping Precedence, frames can be dropped toavoid congestion

– A queue will allow fewer “yellow” frames than “green” frames

• 4 traffic classes, 4 egress queues per port


....................................................................................................................................................................................................................................365-312-847R4.0Issue 4, November 2006


2-25

Each QOS profile contains a Traffic Class (TC) entry.

– The traffic class determines the relative priority of a frame based on the trafficclass to queue assignment function and the scheulder settings

– The traffic class determines the outgoing p-bits for the egress direction

• Egress queue scheduling with strict Priority and/or Weighted Bandwidth options.

Sl-14/8 option card

Interfaces

On the faceplate, the Sl-14/8 card provides:

• Eight cages for Small Form-factor Pluggable (SFP) optical transceivers

• SFP-1 and SFP-5 support for STM-1 or STM-4 interfaces

• SFP-2 to SFP-4 and SFP-6 to SFP-8 support for STM-1 interfaces.

The board supports 1.2 Gigabit interfaces and provides a total transmission capacity ofeight VC-4s. This capacity is divided into two VC-4 groups namely, the SFP-1 toSFP-4 group and the SFP-5 to SFP-8 group. Each group provides a four VC-4transmission capacity. For example, if the SFP-1 is equipped with an STM-4 interface,the SFP-2 to SFP-4 have no more capacity and cannot be used. Similarly, if the SFP-5is equipped with an STM-4 interface, the SFP-6 to SFP-8 is being utilized andtherefore cannot be used for any additional capacity.

Each SFP transceiver has an LED which indicates three states. When the LED is on, itindicates hardware failures and confugration alarm. When the LED is blinking, itindicates transmission failure. When there are no failures, the LED is off. A fault onthe SFP is indicated by an LED on the SFP itself and not on the host unit’s LED.

The STM-1 and STM-4 in-loop and out-loop loopbacks are achieved by thecross-connect functionality.

The following figure shows the front panel of the Sl-14/8 option card.

X2E3-V2 option card (legacy)

The X2E3-V2 option card provides two bidirectional 34 Mbit/s (E3) interfaces.

X2DS3-V2 option card (legacy)

The X2DS3-V2 option card provides two additional 45 Mbit/s (DS3) interfaces.

X16DS1 option card (legacy)

The X16DS1-V3 option card provides 16 additional 1.5 Mbit/s (DS1) interfaces.

X8PL option card (legacy)

The X8PL option card provides eight Ethernet interfaces in Private Line mode for theMetropolis® AMU. The Private Line mode enables traffic to be mapped from eachEthernet port one-to-one into an SDH container. Thus a private connection from anEthernet port through an SDH network to another Ethernet port at the remote end ofthe link is possible.

The X8PL option card supports a flexible allocation of SDH bandwidth to LAN portsby making use of the Link Capacity Adjustment Scheme (LCAS, see“LCAS” (p. 3-22)). All LAN ports have the same capabilities. Each WAN port supports VC-12-Xv (X =1...63) or VC-3-Xv (X = 1...3).

The VC-12s that form one VCG can be chosen from any TUG-3, in any timeslot order.However, it is recommended to select the VC-12s in sequential order, preferably in one

TUG-3. In this way the end-to-end network design can be kept simple and easy tomaintain.

To use the X8PL card in theMetropolis® AMU, an adapter card is required, see“Adapter card for legacy option cards (for 2m/4o version only)” (p. 2-28)

X4IP-V2 option card (legacy)

On theMetropolis® AMU an Ethernet LAN option board (X4IP-V2) is availableproviding four 10/100BASE-T Ethernet interfaces. When equipped with an option card,Lucent Technologies SDH multiplexers can offer 10/100BASE-T Ethernet interfacesbesides the standard TDM services like DS1, E1, E3/DS3, E4, STM-1 and STM-4.Below a description is given of the X4IP-V2 option card functionality supported by theMetropolis® AMU.

Ethernet WAN port capacity configuration rules

The encapsulated Ethernet frames are mapped in VC-12 (2 Mbit/s), VC-12-2v (4Mbit/s), VC-12-3v (6 Mbit/s), VC-12-4v (8 Mbit/s), VC-12-5v (10 Mbit/s), VC-3 (50Mbit/s) or VC-3-2v (100 Mbit/s). A user can provision the actual bandwidth per WANport. Since the cross-connect capacity of aMetropolis® AMU is limited, the totalcombined bandwidth of all WAN ports together must follow the WAN capacityconfiguration rules defined in the table below.

The throughput mentioned in the table above are the maximum settings, it is alsopossible to have less throughput for a certain WAN port (for example 6 Mbit/s(VC-12-3v)).

Notice that only the WAN port bandwidth dictates the effective end-to-end Ethernetcommunication throughput, not the LAN ports. TheMetropolis® AMU equipped withthe TransLAN® option board keep track of the available capacity according to the rulesdefined in the WAN port configuration table above. If an attempt to configure a newWAN port capacity violates the rules, not only the system will not grant the newconfiguration but also an alarm (message) will be triggered and displayed.

Ethernet WAN port mapping

The WAN port mapping of the X4IP-V2 is shown in the following table. In case theunits in service do not use the same termination points, adaptation via the LO crossconnect is required.

Advanced TransLAN® Features...................................................................................................................................................................................................................................

Ethernet Performance Monitoring (ESW4_E14)

Ethernet Performance Monitoring in SDH network elements is based on SDHperformance monitoring concepts. The following sections describe the advancedTransLAN® features that are implemented for Ethernet applications.

Round Trip Delay Measurement (RTD)

The following features enable Round Trip Delay measurement:

• One Shot Ethernet In-Service RTD Measurement - FROM Node

• Continuous Ethernet In-Service RTD Measurement - FROM Node

• RTD Measurement Accuracy

• Proprietary Ethernet In-Service RTD Measurement

One Shot Ethernet In-Service RTD Measurement - FROM Node

The virtual switches in the network element support proprietary in-service round tripdelay measurement by transmitting a special “ping” PDU from the local virtual switchthat is identified as the FROM Node to a remote switch that is identified as the TOnode. The TO node is identified by a MAC address. A ping frame with a definedlength can be sent with a certain VLAN, priority, and dropping precedence provisionedby the user. Based on the responses from the remote node, the round trip time iscalculated. The result is presented to the user as a delay in milliseconds or a time-out.

Continuous Ethernet In-Service RTD Measurement - FROM Node

Users can provision a continuously repeating round trip delay measurement with thefollowing parameters.

• FROM node virtual switch

• TO node MAC address

• Frame length

• V-LAN

• Traffic class

• Dropping precedence

The repitition rate is approximately 45 seconds. The results are presented in thePerformance Monitoring format. For more information, refer the Metropolis® AMUUser Operations Guide.

Proprietary Ethernet In-Service RTD Measurement - TO Node

Protocol data units (PDUs) that are transmitted by a remote Ethernet switch forin-service round trip measurement purposes (which are addressed to a local Ethernetswitch in the system) provide the appropriate response.

Static MAC Address Table Configuration and Retrieval

The following features support static MAC address table configuration and retrieval.

• Manual unicast MAC address provisioning

• Manual multicast MAC address provisioning

• Delete/View dynamic entry from filtering database

• Port security by S-MAC address based access list

• Flushing the filtering database

• Limited automatic MAC address learning capacity per VLAN

• Provisionable MAC address ageing timer.

Manual Unicast MAC Address Provisioning

Users can view, create, and delete a unicast MAC address to and from the filteringdatabase of an Ethernet switch unit. A unicast MAC address entry in the filteringdatabase consists of a unicast MAC address, a V-LAN entry, and a destination port.Upon request, the user can view the entire list of provisioned static entries from thefiltering database of a switch unit. For more information, refer the Metropolis® AMUUser Operations Guide.

Manual Multicast MAC Address Provisioning

Users can view, create, and delete a multicast/broadcast MAC address to and from thefiltering database of an Ethernet switch unit. A multicast/broadcast MAC address entryin the filtering database consists of the multicast/broadcast MAC address, a V-LANentry, and a destination port list. Upon request, the user can view the entire list ofprovisioned static entries from the filtering database of a switch unit. This feature isonly applicable on the ESW4_E14 option card. For more information, refer theMetropolis® AMU User Operations Guide.

Delete/View Dynamic Entry from Filtering Database

Users can search for specific and dynamically learnt MAC addresses or V-LAN entriesin the filtering database of an Ethernet switch unit. If the specified entry is present, theassociated destination port is displayed. When required, such an entry can be deletedfrom the filtering database. This feature is only applicable to the ESW4_E14 optioncard. For more information, refer the Metropolis® AMU User Operations Guide.

Port Security by S-MAC Address based Access List

Users can lock or unlock an Ethernet switch port. On a locked port, the automaticaddress learning feature is disabled and all frames of the source MAC address that donot appear in the access list are dropped. An access list from the filtering database ofthe Ethernet switch is used. Before a frame is allowed to enter a locked port, thesource MAC address with the proper V-LAN number and port number must be presentin the filtering database.

Flushing the Filtering Database

When required, the user can delete all dynamically learnt addresses from the filteringdatabase of an Ethernet unit. For more information about this procedure, refer theMetropolis® AMU User Operations Guide. This feature is only applicable to the

Cross-connection features...................................................................................................................................................................................................................................

Cross-connection rates

Metropolis® AMU supports bidirectional cross-connections for VC-12, VC-3 and VC-4.The cross connect matrix is 100% flexible and non blocking.

The main unit supports loopbacks on incoming STM-N signals. Loopbackcross-connections are possible on VC-12 and VC-3 level as well as VC-4 level.

Transparent DCC cut-through

The MI-16/4 system supports up to 20 bi-directional connections for transparent DCCforwarding through the system from one STM-N port to another. Each bi-directionalconnection can support a transparent link for the DCC-RS or the DCC-MS or bothDCC channels associated with a single STM-N interface. However, note that only 20bi-directional connections can be supported with a combination of the MI-16/4 mainunit and the Sl-14/8 unit.

The MI-14/4 system supports up to eight bidirectional connections for transparent DCCforwarding through the system from STM-N port to another. Each connection cansupport transparent link for the DCC-RS or the DCC-MS or both DCC channelsassociated with a single STM-N interface.

The supported framing method is HDLC.

Please note that the same pool of connections that are available for Transparent DCCcut-through is also required for connecting the DCC of an STM-N port to the internalIS_IS router. This means a restriction on the number of available connections for DCCcut-through purposes.

Slaved switching for MSP is applicable to transparent DCC cut-through connections.

The Metropolis® AMU cross-connection function provides the following DCC features.

• Upto 40 MS-DCC and 40 RS-DCC terminations per system (4 from both mainunits, 8 from each tributary slot); via 2 TDM ports and a separate TDM port forin-band management channels. Users can access RS-DCC or MS-DCC or bothDCC channels of at most 16 different STM-N interfaces (including line andtributary).

• DCC support on STM-16 optical line interfaces via D1-3. The OSI layer 2 and 3functionality is supported via the RS-DCC channel of the STM-16 optical lineinterface. Each RS-DCC channel can be enabled or disabled individually.

• DCC support on STM-16 optical line interfaces via D4-12. The OSI lsyer 2 and 3functionality is supported via the MS-DCC channel of the STM-16 optical lineinterface. Each MS-DCC channel can be enabled or disabled individually.

Transmission protection...................................................................................................................................................................................................................................

Supported protection mechanisms

To guarantee service availability, these transmission protection mechanisms aresupported by theMetropolis® AMU:

• Multiplex Section Protection (MSP) 1 + 1

– 1+1 MSP protection for optical and electrical STM-1 and opticalSTM-4/STM-16 interfaces.The protection switching can be configured revertive and non-revertive as wellas unidirectional and bidirectional (i.e. both directions of transmission are,respectively, switching separately or jointly). But the remote end of theMultiplex section must support the necessary features for this operation. AnySTM-N port combination with the same transmission rate can be used as acombination of line and tributary SDH ports.Forced, manual and lockout switch commands are supported. The MSPimplementation is compliant with the ITU-T Rec. G.841/Clause 7.1 and ETS300417-3-1 (i.e. the APS protocol is optimized for 1:N protection). ETSI failureof protocol applies. Under this protocol also an alarm-free interworking modewith SONET defined MSP is supported.The maximum switch completion time is 50 ms.

• Subnetwork Connection Protection (SNCP)

– VC-12 SNC/N protection (non-revertive)A non-intrusively monitored subnetwork connection protection (SNC/N) relationcan be set up between any arbitrary incoming TU-12 from any STM-N and anyother arbitrary incoming TU-12 from any STM-N interface (VC-12s aremapped into TU-12s).Only non-revertive operation is possible. Manual and forced switch commandsare supported. In the return channel the signal is simply bridged to bothoutputs.The maximum switch completion time is 50 ms.

– Lower order VC-3 SNC/N protection (non-revertive)A non-intrusively monitored subnetwork connection protection (SNC/N) relationcan be set up between any arbitrary incoming TU-3 from any STM-N interfaceand any other arbitrary incoming TU-3 from any STM-N interface.Only non-revertive operation is possible. Manual and forced switch commandsare supported. In the return channel, the signal is simply bridged to bothoutputs. note that hardware based SNCP switching for can be implemented forlower order VC-12 and VC-3s.The maximum switch completion time is 50 ms.

– Higher order VC-4 SNC/N protection (non-revertive)A non-intrusively monitored subnetwork connection protection (SNC/N) relationcan be set up between any arbitrary incoming TU-3 from any STM-N interfaceand any other arbitrary incoming TU-3 from any STM-N interface.Only non-revertive operation is possible. Manual and forced switch commandsare supported. In the return channel the signal is simply bridged to bothoutputs.The maximum switch completion time is 50 ms.

Equipment protection...................................................................................................................................................................................................................................

Supported protection mechanisms

Metropolis® AMU provides the following equipment protection mechanisms (mainboard based)

• 1+1 revertive equipment protection of the cross-connection function

• Equipment protection of the power supply filter function

• Equipment protection of the timing function

Equipment protection of cross-connection and timing function

If two units are present in the system an automatic protection switch relation can be setup by the user. The switching is revertive. This means that the service returns to theMain board 2 when both boards are working. Manual operation of the protection issupported and the unprotected operation is possible as well. The traffic interruptiontime is less than 50 ms with manual switch commands and less than 50 ms plus thedetection time for automatic protection switches triggered by a failure. The unit that isnot active can be pulled or replaced without causing bit errors in the traffic.

Important! Please note that the CIT, EOW, Q-LAN and MDI/MDO interfaces onthe Main board 2 are not operational.

Equipment protection of the power filter function

If two units are present in the system, both power filter parts are active.

Auto-negotiation...................................................................................................................................................................................................................................

Auto-negotiation

The Auto-negotiation function automatically configures the Ethernet interfaceparameters to establish an optimal Ethernet link based on the capabilities of thenear-end and far-end Ethernet interfaces.

Auto-negotiation for twisted-pair systems, defined in Clause 28 of the Standard802.3-2002, has been extended to include all three speeds of Ethernet that aresupported over twisted-pair cable: 10Mbit/s 10Base-T, 100Mbit/s 100Base- TX, and1000 Mbit/s 1000Base-T.

The physical signaling portion of all three twisted-pair systems use the sameAuto-negotiation signaling standard. While Auto-negotiation can be disabled on10Base-T and 100Base-TX links, it is required on 1000- Base-T systems since GigabitEthernet systems use Auto-negotiation to establish the master-slave signal timingcontrol that is required to make the link operational. For more information about themaster-slave mode, please refer the Metropolis® AMU User Operations Guide.

To be able to override the Auto-negotiation function, it is possible to disableAuto-negotiation. This might be needed if Auto-negotiation cannot establish a link or ifa specific link speed / mode is required.

Link Capacity Adjustment Scheme (LCAS)...................................................................................................................................................................................................................................

LCAS

The X8PL, EPL4_E14, and EPL4_E132_75 option cards for Ethernet private lineapplications and the ESW4_E14 Ethernet option card support the Link CapacityAdjustment Scheme (LCAS).

LCAS defines a synchronization protocol between two termination points of a virtualconcatenated path that allows in-service dynamic sizing of the VCn-Xv bandwidth thatis available for Ethernet-over-SDH transmission. This bandwidth change can occureither in response to a failure condition on one member or a requirement for a changein bandwidth at an NE (provisioning action).

In case of failure, the bandwidth will be restored automatically after the failure clears.The size of the VCn-Xv is increased or decreased in steps of one VCn. Theprovisioning is performed by adding/removing paths to/from the Ethernet tributarycard.

The default LCAS hold-off timer is set to zero so that the LCAS mechanism will takeimmediate action. However, if the path over which the LCAS protocol is run isprotected by a transmission protection mechanism such as MSP or SNCP the LCAShold-off timer value should be raised (~100 ms) to allow the generally faster MSP orSNCP protection mechanisms to react before the LCAS undertakes any repair attempts.In this way less packets are lost.

Link Pass Through (LPT)...................................................................................................................................................................................................................................

LPT

The Ethernet interface supports Link Pass Through mode. The Ethernet port transmitteris disabled in case of failures in the upstream network. For example, a remote Ethernetcable or optic fiber failure, an SDH/SONET network failure or any equipment failure.The downstream equipment, a LambdaRouter or an IP router, will observe the absenceof the Ethernet input signal and use it as a fast trigger to perform its native protectionscheme. The remote failures are transported in-band via the GFP-Client Signal Failmessage. The LPT is only supported on ports that operate in a one-to-one associationwith a WAN port. The option cards EPL4_E14, EPL4_E132_75, and ESW4_E14support the LPT mode.

Metropolis® AMU provides one external timing input and output per main card forITU-T compliant 2048 kHz / 2048 kbit/s timing signals. The timing output is realizedas RJ45 connector suitable for symmetrical twisted pair cables with an impedance of120 Ω or coaxial cables with an impedance of 75Ω.

2 Mbit/s tributary retiming

The user can choose whether individual 2 Mbit/s tributary outputs operate in“self-timed” or “re-synchronized” mode. In the (standard) self-timed mode, the phaseof the outgoing signal is a moving average of the phase of the 2 Mbit/s signal becausethe signal is embedded in the VC-12 that is disassembled. In the re-synchronized modethe 2 Mbit/s signal is timed by the SDH Equipment Clock (SEC) of the networkelement; frequency differences between the local clock and the 2 Mbit/s signalembedded in the VC-12 to be disassembled are accommodated by a slip buffer.

There is also the following option: whenever the traceability of the local clock dropsbelow a certain threshold, the re-timing 2 Mbit/s interfaces automatically switch toself-timing. When this fail condition disappears, these interfaces return to re-timing.These changes do not involve any hits in the traffic.

Important! Re-timing should only be applied when the network element whichperforms the re-timing and the network element which generated the 2 Mbit/ssignal have traced back their SECs to the same synchronization source. Otherwise acontinuous stream of 2 Mbit/s frame slips or skips will occur at the re-timing pointwhich is indicated by a FCS threshold crossing alarm.

The user has the option of operating individual 2 Mbit/s outputs in the“re-synchronized” mode. In this mode the 2 Mbit/s output signal is timed by thesystem clock of the network element.

Remote maintenance, management, and control...................................................................................................................................................................................................................................

First maintenance tier

The maintenance procedures of theMetropolis® AMU systems are built on two levelsof system information and control. The first maintenance tier consists of the LEDs onthe equipment. There are six LEDs on the front of the main board ofMetropolis®

AMU: Two are for unit level indications and four for failure indications related to eachindividual SFP. Additionally there are LEDs on option cards and near to the SFPs. TheLEDs indicate basic alarms or basic operation states.

Second maintenance tier

The second maintenance tier employs the Lucent Technologies network managementsystem. Detailed information and system control are obtained by using the ITM-CIT(Craft Interface Terminal), which supports provisioning, maintenance and configurationon a local basis. A similar facility (via a Q-LAN connection or via the DCC channels)is remotely available on the element manager or through Lucent’s NetworkManagement Systems or Lucent NMS, which provides a centralized maintenance viewand supports maintenance activities from a central location.

Lucent Network Management Systems

Lucent’s Network Management Systems or the Lucent NMS fully support themanagement ofMetropolis® AMU.

Fan Management

A fan is available for mounting below the 2m/4o version, below the vertically mounted1m/1o version (1 per shelf) or next to the horizontally mounted 1m/1o version (1 pershelf). The same fan can be used in all cases. The fan is in-service replaceable,provided that proper care is taken with the cabling. The fan is powered and managedvia the USB interface on the front of (one of the) Main Units. For more details, referthe Metropolis® AMU User Operations Guide.

Note: When two fans are placed under the 2m/4o version, 2 trib slots and 2 main slotsor 4 trib slots can be cooled effectively.

The presence of USB powered/controlled fans can be established on a remotemanagement system. Provisioning of fans is not necessary; they are auto-provisionedafter autonomous detection by the AMU hardware. Alarms will be raised if a fan failsor is removed.

Special Mounting Brackets

To use the horizontally positioned 1m/1o version in combination with a fan unit, itmust be mounted with a specific mounting bracket that allows sliding in and out of thefan unit.

• Equipment protection: A system equipped with two main cards can either operate inequipment protection mode, or alternatively, the main card in slot MAIN2 operatesas a tributary card. The latter is easier to manage, but does not provide automaticswitch over in case of equipment failures in the transmission and timingfunctionality of the main cards.

• Operations Systems: Remote management with Lucent’s Network ManagementSystems or Lucent NMS and local management with Wavestar® ITM-CIT

• Two possibilities for Power supply :

– DC (unit contains DC connector)

– AC via an external AC/DC connector.

• The Metropolis® AMU provides four miscellaneous discrete inputs (MDIs) whichcan be used to read external devices assigned by the customer. Examples aremonitoring temperature, humidity, open doors, etc.The equipment provides four miscellaneous discrete outputs (MDOs) which can beused to drive external devices assigned by the customer. Examples are signalingdevices, temperature conditioning, etc.When not assigned by the customer, theMetropolis® AMU behave such thatMDO1 has been assigned to indicate power failure (this contact is normally closedwhen no power is present). MDO 2, MDO 3, MDO 4 are respectively assigned toPrompt, Deferred, Information alarms.

Dual-homed ring application...................................................................................................................................................................................................................................

The figure below shows an example of a dual-homed ring application. Similar to thesingle-homed example in the previous chapter, access to the STM-N network isthrough two hosts. This may be preferable to the single-host application wherecompleting the STM-1 or STM-4 or STM-16 ring may be difficult due to geographicalfeatures. It also provides protection against node failure through the second host node.

IP Tunneling in the DCC channels application...................................................................................................................................................................................................................................

The figure below shows an example of the IP tunneling in the DCC channelsapplication. This feature provides a way to manage IP devices through the DataCommunication Network (DCN). An IP EMS (Element Management System) is usedto manage NEs which use IP based management protocols (IP NEs).

The embedded overhead channel (Data Communication Channel) of theMetropolis®

AMU is used to transport the management data between the IP EMS and the differentNEs.

An IP tunnel can be seen as a set of two static routing entries in nodes on the edge ofthe OSI network and the corresponding static entries in the routing table. The LANused by IP EMS can also be used by Lucent’s Network Management Systems orLucent NMS.

The figure below shows an application with AnyMedia Access equipments (AAS). TheEMS for AAS realizes the management of the different AAS equipments via theQ-LAN interfaces and using the DCC channels of the differentMetropolis® AMU.

Multi-service application with theTransLAN® option board...................................................................................................................................................................................................................................

The TransLAN® option board, enables the SDH network elements to provide Ethernetover SDH, and offers variable data applications on top of the traditional TDMapplications. This results in cost-effective, simple and reliable multi-service solutionsfor customers.TransLAN® can provide VLAN functions, and bandwidth can be sharedfor different customers.

Direct LAN-to-LAN interconnect (two LAN’s)

The most straightforward application of theTransLAN® option board is to interconnecttwo LAN segments that are at a distance that cannot be reached with a simple Ethernetrepeater, since that would violate the collision domain size rules. Both LAN’s do nothave to be of the same speed. It is possible to interconnect a 10BASE-T and a100BASE-T/X LAN this way. This application is shown in the figure below:

Direct LAN-to-LAN interconnect (Multiple LAN’s)

A next step in complexity is to interconnect multiple LAN’s, more than two, atdifferent locations. It is possible to associate a single LAN port with two or moreWAN ports. In this way, multiple sites can be interconnected, forming a fully Layer 2switched WAN Ethernet network. This application is shown in the figure below.

LAN-ISP interconnect

An extension of the previous application is to have one LAN drop of a multi-pointLAN-to-LAN interconnection at the point of presence of an ISP (Internet ServiceProvider), to provide for instance Internet access to the users in the company LANs.

Multiple customers sharing a WAN connection

To increase the efficiency of the bandwidth usage, it is possible to route the Ethernettraffic of multiple end-users over the same SDH facilities. This feature is calledLAN-VPN and makes use of customer VPN tags, a tagging scheme derived from theIEEE802.1Q VLAN standard to separate the traffic of the different users. Thefollowing image displays this application.

VLAN Trunking

At the ISP premises, the aggregated LAN traffic from multiple customers (i.e. multipleVLANs) via one single high capacity Ethernet link (Fast Ethernet) to data equipmentin a Central Office or ISP POP such as an IP edge Router, IP Service Switch or ATMSwitch, can be handled by means of the VLAN trunking feature. VLAN trunking is apossible application of the IEEE 802.1Q or the IEEE 802.1ad VLAN tagging scheme.Main benefit of the VLAN trunking feature is thatTransLAN® cards can hand off enduser LAN traffic via one high capacity LAN port instead of multiple low speed LANports, thus reducing port, space and cabling costs.“VLAN Trunking” (p. 4-21) givesan example of VLAN Trunking.

DCN support with the TransLAN ® unit

The TransLAN® option board can also be used for DCN engineering purposes. Animportant application in this respect is to use the Ethernet interfaces to make a longdistance Q-LAN connection. This solution can replace the current solution that usesexternal modems or routers. It is often cheaper and easier to manage if the longdistance Q-LAN connection can be made over the SDH infrastructure (at the cost ofthe bandwidth of a few VC-12s). The DCN application of theTransLAN® option boardassumes the NMS is collocated with at least one of the NEs equipped with aTransLAN® card (e.g.,Metropolis® AMU, Metropolis® ADM (Universal shelf) orMetropolis® ADM (Compact shelf). In such a case, one can connect the Ethernet portof the Lucent NMS to one of the designated 10BASE-T/100BASE-TX LAN ports andconfigure the associated WAN port with desired bandwidth (e.g., VC-12) to carry themanagement traffic.

Point-to-point LAN connection...................................................................................................................................................................................................................................

The point-to-point LAN connection is used to interconnect two sites of a customereach of which has a LAN interface. Another application is the interconnection of thesites of two service providers that have Ethernet interfaces.

Some dedicated SDH bandwidth is allocated to the connection between both endpoints. The virtual concatenation mapping allows the operator to assign an optimizedSDH bandwidth. Such an application can effectively be realized withMetropolis®

AMU using one of the private line option cards which provide the GFP and LAPSEthernet mapping schemes and the LCAS protocol (please refer to“Ethernet features”(p. 3-19), “Ethernet mapping schemes” (p. 3-24)and“Link Capacity AdjustmentScheme (LCAS)” (p. 3-22)).

The following figure shows an example of a point-to-point LAN connection:

The ESW4_E14 option card supports point-to-point LAN connections with Ethernetswitching. This allows statistical multiplexing and as a result, higher bandwidthefficiency. TheMetropolis® AMU1m/1o version with ESW4_E14 and EPL4_E14option cards presents a very efficient way for full throughput Gigabit Ethernet access atlow costs. The Gigabit Ethernet connection can be transported using 2 STM-4 linksand virtual concatenation and LCAS distributed over both links.

Mean time between failures

The mean time between failures (MTBF) for the wholeMetropolis® AMU aredescribed in“Metropolis® AMU circuit-pack fit rates and MTBF values” (p. 5-12).

Infant mortality factor

Note: The steady state failure rate is equal to the failure rate of the system.

The number of failures that a product experiences during the first year of service afterturn-up may be greater than the number of subsequent annual steady state failures. Thisis the early life or infant mortality period. The ratio of the first year failure rate to thesteady state failure rate is termed the infant mortality factor (IMF).

Appendix A: An SDH overview

Overview...................................................................................................................................................................................................................................

Purpose

This chapter briefly describes the Synchronous Digital Hierarchy (SDH).

Synchronous Digital Hierarchy

In 1988, the ITU-T (formerly CCITT) came to an agreement on the SynchronousDigital Hierarchy (SDH). The corresponding ITU-T Recommendation G.707 forms thebasis of a global, uniform optical transmission network. SDH can operate withplesiochronous networks and therefore allows the continuous evolution of existingdigital transmission networks.

The major features and advantages of SDH are:

• Compatibility of transmission equipment and networks on a worldwide basis

• Uniform physical interfaces

• Easy cross connection of signals in the network nodes

• Possibility of transmitting PDH (Plesiochronous Digital Hierarchy) tributary signalsat bit rates commonly used at present

• Simple adding and dropping of individual channels without special multiplexers(add/drop facility)

• Easy transition to higher transmission rates

• Due to the standardization of the network element functions SDH supports asuperordinate network management and new monitoring functions and providestransport capacity and protocols (Telecommunication Management Network, TMN)for this purpose in the overheads of the multiplex signals.

• High flexibility and user-friendly monitoring possibilities, e.g. end-to-endmonitoring of the bit error ratio.

Purpose of SDH

The basic purpose of SDH is to provide a standard synchronous optical hierarchy withsufficient flexibility to accommodate digital signals that currently exist in today’snetwork, as well as those planned for the future.

....................................................................................................................................................................................................................................365-312-847R4.0Issue 4, November 2006


A-1

SDH currently defines standard rates and formats and optical interfaces. Today,mid-span meet is possible at the optical transmission level. These and other relatedissues continue to evolve through the ITU-T committees.

ITU-T addressed issues

The set of ITU-T Recommendations defines

• Optical parameters

• Multiplexing schemes to map existing digital signals (PDH) into SDH payloadsignals

• Overhead channels to support standard operation, administration, maintenance, andprovisioning (OAM&P) functions

• Criteria for optical line Automatic Protection Switch (APS)

SDH signal hierarchy...................................................................................................................................................................................................................................

This section describes the basics of the SDH hierarchy.

STM-1 Frame

The SDH signal hierarchy is based on a basic “building block” frame called theSynchronous Transport Module 1 (STM-1), as shown in“SDH STM-1 frame” (p. A-5).

The STM-1 frame has a rate of 8000 frames per second and a duration of 125microseconds

The STM-1 frame consists of 270 columns and 9 rows.

Each cell in the matrix represents an 8-bit byte.

Transmitting Signals

The STM-1 frame (STM = Synchronous Transport Module) is transmitted seriallystarting from the left with row 1 column 1 through column 270, then row 2 column 1through 270, continuing on, row-by-row, until all 2430 bytes (9x270) of the STM-1frame have been transmitted. Because each STM-1 frame consists of 2430 bytes andeach byte has 8 bits, the frame contains 19440 bits a frame. There are 8000 STM-1frames a second, at the STM-1 signal rate of 155.520.000 (19440 x 8000) kbit/s.

Three higher bit rates are also defined:

• 622.080 Mbit/s (STM-4)

• 2488.320 Mbit/s (STM-16)

• 9953.280 Mbit/s (STM-64)

• 39813.120 Mbit/s (STM-256)

The bit rates of the higher order hierarchy levels are integer multiples of the STM-1transmission rate.

SDH STM-1 frame

The following figure illustrates the SDH STM-1 frame.

365-312-847R4.0Issue 4, November 2006

Section overhead (SOH)

The first nine bytes of each row with exception of the fourth row are part of the SOH(Section OverHead). The first nine byte of the fourth row contain the AU pointer (AU= Administrative Unit).

STM-1 payload

Columns 10 through 270 (the remainder of the frame), are reserved for payloadsignals.

SDH path and line sections...................................................................................................................................................................................................................................

This section describes and illustrates the SDH path and line sections.

SDH layers

SDH divides its processing functions into the following three path and line sections:

• Regenerator section

• Multiplex section

• Path

These three path and line sections are associated with

• Equipment that reflects the natural divisions in network spans

• Overhead bytes that carry information used by various network elements

Equipment layers

The following table lists and defines each SDH equipment path and line section.

Path and linesections

Definition

Regenerator section A regenerator section describes the section between two networkelements. The network elements, however, do not necessarilyhave to be regenerators.

Multiplex section A multiplex section is the section between two multiplexers. Amultiplex section is defined as that part of a path where nomultiplexing or demultiplexing of the STM-N frame takes place.

Path A path is the logical signal connection between two terminationpoints.

A path can be composed of a number of multiplex sectionswhich themselves can consist of several regenerator sections.

Path, MS and RS

The following figure illustrates the equipment path, multiplex sections and regeneratorsections in a signal path.

Path overhead

The Path Overhead (POH) is generated for all plesiochronous tributary signals inaccordance with ITU-T Rec. G.709. The POH provides for integrity of communicationbetween the point of assembly of a Virtual Container VC and its point of disassembly.The following table shows the POH bytes and their functions.

Byte Location and Function

J1 Path Trace Identifier byte

B3 Path Bit Interleaved Parity (BIP-8)

Provides each path performance monitoring. This byte is calculatedover all bits of the previous payload before scrambling.

C2 Signal Label

All ″0″ means unequipped; other and″00000001″ means equipped

G1 Path Status

Conveys the STM-1 path terminating status, performance, and remotedefect indication (RDI) signal conditions back to an originating pathterminating equipment.

F2, F3 User Data Channel

Reserved for user communication.

H4 Multiframe Indicator

Provides a general multiframe indicator for VC-structured payloads.

K3 VC Trail protection.

N1 Tandem connection OH

AU pointer

The AU pointer together with the last 261 columns of the STM-1 frame forms an AUG(Administrative Unit Group). An AUG may contain one AU-4 or threebyte-multiplexed AU-3s (an AU-3 is exactly one third of the size of an AU-4). AU-3sare also compatible with the SONET standard (Synchronous Optical NETwork) whichis the predecessor of SDH (and still the prevailing technology within the USA). Threebyte-multiplexed STS frames (SONET frame), each containing one AU-3 can bemapped into one STM-1.

SDH digital multiplexing...................................................................................................................................................................................................................................

Digital multiplexing is SDH’s method of byte mapping tributary signals to a highersignal rate, which permits economical extraction of a single tributary signal without theneed to demultiplex the entire STM-1 payload. In addition, SDH provides overheadchannels for use by OAM&P groups.

SDH digital multiplexing

The following figure illustrates the SDH technique of mapping tributary signals intothe STM frames.

Transporting SDH payloads

Tributary signals are mapped into a digital signal called a virtual container (VC). TheVC is a structure designed for the transport and switching of STM payloads. There arevarious sizes of VCs: VC-11, VC-12, VC-2, VC-3, VC-4, VC-4-4C, VC-4-16C,VC-4-64C and VC-4-256C.

SDH multiplexing process...................................................................................................................................................................................................................................

SDH provides for multiplexing of 2-Mbit/s (C-12) and 34-Mbit/s (C-3) signals into anSTM-1 frame.

Furthermore, multiplexing paths also exist for the SONET specific 1.5-Mbit/s, 6-Mbit/sand 45-Mbit/s signals.

Process

The following describes the process for multiplexing a 2-Mbit/s signal. The“SDHdigital multiplexing” (p. A-11)illustrates the multiplexing process.

...................................................................................................................................................................................................

1 Input 2-Mbit/s tributary is mapped

• Each VC-12 carries a single 2-Mbit/s payload.

• The VC-12 is aligned into a Tributary Unit TU-2 using a TU pointer.

• Three TU-2 are then multiplexed into a Tributary Unit Group TUG-2.

• Seven TUG-2 are multiplexed into an TUG-3.

• Three TUG-3 are multiplexed into an VC-4.

• The VC-4 is aligned into an Administrative Unit AU-4 using a AU pointer.

• The AU-4 is mapped into an AUG which is then mapped into an STM-1 frame.

...................................................................................................................................................................................................

2 After VCs are multiplexed into the STM-1 payload, the section overhead is added.

...................................................................................................................................................................................................

3 Scrambled STM-1 signal is transported to the optical stage.

SDH demultiplexing process...................................................................................................................................................................................................................................

Demultiplexing is the inverse of multiplexing. This topic describes how to demultiplexa signal.

Process

The following describes the process for demultiplexing an STM-1 signal to a 2 Mbit/ssignal. The“SDH digital multiplexing” (p. A-11)illustrates the demultiplexing process.

...................................................................................................................................................................................................

1 The unscrambled STM-1 signal from the optical conversion stages is processed toextract the path overhead and accurately locate the payload.

...................................................................................................................................................................................................

2 The STM-1 path overhead is processed to locate the VCs. The individual VCs are thenprocessed to extract VC overhead and, via the VC pointer, accurately locate the2-Mbit/s signal.

...................................................................................................................................................................................................

3 The 2-Mbit/s signal is desynchronized, providing a standard 2-Mbit/s signal to theasynchronous network.

Key points

SDH STM pointers are used to locate the payload relative to the transport overhead.

Remember the following key points about signal demultiplexing:

• The SDH frame is a fixed time (125 µs) and no bit-stuffing is used.

• The synchronous payload can float within the frame. This is to permitcompensation for small variations in frequency between the clocks of the twosystems that may occur if the systems are independently timed (plesiochronoustiming).

SDH transport rates...................................................................................................................................................................................................................................

Higher rate STM-N frames are built through byte-multiplexing of N STM-1 signals.

Creating higher rate signals

A STM-N signal can only be multiplexed out of N STM-1 frames with their first A1byte at the same position (i.e. the first A1 byte arriving at the same time).

STM-N frames are built through byte-multiplexing of N STM-1 signals. Not all bytesof the multiplexed SOH (size= N x SOH of STM-1) are relevant in an STM-4/16.

For example there is only one B1 byte in an STM-4/16 frame which is computed thesame way as for an STM-1. Generally the SOH of the first STM-1 inside the STM-Nis used for SOH bytes that are needed only once. The valid bytes are given in ITU-TG.707.

Geographic Redundancy (GR)Allows protection of management for a network element by assigning the networkelement to two OMSs. The first primary OMS usually manages the Network Elementand is now in the protected domain. If the primary OMS or the link between the networkelement and the primary OMS fails, the secondary OMS will automatically take overmanagement of the network element and is now in the protecting domain. The twoOMSs are connected by a peer to peer link, which they use to pass GeographicRedundancy management information to each other. This link must be established beforeany network element can be protected by Geographic Redundancy.

ISIn-Service

IS-IS RoutingThe network elements in a management network, route packets (data) between each otherusing an IS-IS level protocol. The size of a network that is running IS-IS Level 1 islimited, and therefore certain mechanisms are employed to facilitate the management oflarger networks. For STATIC ROUTING, it is possible to disable the protocol over theLAN connections and thereby effectively cause the management network to bepartitioned into separate IS-IS Level 1 areas. In order for the NMS to communicate witha specific network element in one of these areas, the NMS must identify the Gatewaynetwork element through which this specific network element is connected to the LAN.All packets to this specific network element are routed directly to the Gateway networkelement by the NMS, before being re-routed (if necessary) within the Level 1 area. ForDYNAMIC ROUTING an IS-IS Level 2 routing protocol is used that allows a number ofLevel 1 areas to interwork. The network elements that connect an IS-IS area to anotherarea are set to run the IS-IS Level 2 protocol within the network element and on theconnection to other network elements. Packets can now be routed between IS-IS areasand the NMS does not have to identify the Gateway network elements.

Non-synchronousThe essential characteristic of timescales or signals such that their significant instants donot necessarily occur at the same average rate.
