For the SSM-32, SW1 to SW6 are used to set the frame ID. SW7 and SW8 are not usedand must be set to OFF. The frame ID is denoted by 6-bit binary number. The frame IDand DIP Switch setting are similar to those in the SSM-256 frame. The difference is thatthe frame ID of the SSM-32 frame is denoted by 6-bit binary number. That is, the frameID = (SW6) (SW5) (SW4)(SW3)(SW2)(SW1).The appearance and structure of the SSM-256 frame and SSM-32 frame are the same whilethe backplanes are different. Distinguish the two frames as follows:– Observe the silkscreen on the backplane.
The silkscreen is located below slots 9 to 12 on the backplane. It is on the side wherethe OMU/MPU is located, rather than the side where the NET is located. The silkscreenmark of the SSM-256 is MBKP, while that of the SSM-32 is BAKP.
– Observe the slot on the backplane.There are 16 slots respectively on the front and back of the backplane of the SSM-256frame. The width of the slots is the same. Each OMB/MPB/TNC board occupies twophysical slots in the SSM-32 frame. Therefore, their corresponding slots on thebackplane also occupy two slots. That is, there are 14 slots respectively on the front andback of the backplane of the SSM-32 frame, and the two slots in the middle are widerthan other slots.
2.4 BackplanesThis describes the SSM frame and backplanes.
SSM-256 FramesFor the SSM-256, the backplane (MBKP) is a standard 9 U central backplane. Its dimension(height x width x thickness) is as follows (The bracket shows the absolute error range):
390.7 (–0.3 to 0) mm x 412.2 (–0.3 to 0) mm x 4.5 (–0.4 to 0.4) mm, that is, 15.4 (0.01 to 0) in.x 16.2 (0.01 to 0) in. x 0.2 (-0.02 to 0.02) in.

The MBKP provides the following signal interconnection channels for the boards in the SSMframe:
l Control signal channel: 100 Mbit/s fast Ethernet (FE) channels and maintenance bus(MBus) from master and slave MOMUs/MMPUs to other boards. The MBus implementsenvironment monitoring, alarm, power-on/off, hot-pluggable and version control. The FEbus implements data configuration, log, performance and management.
l High-speed TDM data channel: 777 Mbit/s high-speed low-voltage differential signaling(LVDS) channel from the MTNB to other TDM service interface boards.
l High-speed packet data channel: 1.25 Gbit/s or 2.5 Gbit/s high-speed LVDS channel fromthe MNET to packet service boards.
l Cascading signal channel: High-speed LVDS channel and low-voltage transistor-transistorlogic (LVTTL) state identification signal channel from the MFLU and MBLU to theMNET and MTNB.
l Clock signal assignment channel: Channel for distributing clock signals provided by theMCLK from the MNET to service boards.
l The backplane provides service boards with –48 V power supply and 5 V MBus powersupply. The pins for power supply, grounding and signals in the backplane are designed indifferent lengths to avoid mis-plugging boards.
SSM-32 FramesFor the SSM-32, the backplane (BAKP) is a standard 9 U central backplane. Its dimension(height x width x thickness) is as follows (The bracket shows the absolute error range):
390.7 (–0.3 to 0) mm x 412.2 (–0.3 to 0) mm x 4.5 (–0.4 to 0.4) mm, that is, 15.4 (0.01 to 0) in.x 16.2 (0.01 to 0) in. x 0.2 (-0.02 to 0.02) in.
The BAKP provides the following signal interconnection channels for the boards in the SSMframe:
l Control signal channel: 100 Mbit/s FE channel and maintenance bus (MBus) from masterand slave MTNCs to other boards. The MBus implements environment monitoring, alarm,power-on/off, hot-pluggable and version control. The FE bus implements dataconfiguration, log, performance and management.
l High-speed TDM data channel: 147 Mbit/s high-speed low-voltage differential signaling(LVDS) channel from the MTNC to other TDM service interface boards.
l High-speed packet data channel: 1.25 Gbit/s high-speed LVDS channel from theMOMB/MMPB to packet service boards.
l Cascading signal channel: the MTNC provides the TDM and control plane cascadingchannels.
l Clock signal assignment channel: the MCLK or CKMB clock subboard sends the clocksignal to the MTNC, and the MTNC distributes the signal to the other service boards.

About This Chapter
This describes the board types, matching limitation, connection between boards, and universalfeatures of the boards.
The boards of the UMG8900 can be divided into two categories in terms of management andmaintenance, that is, logical board and physical board.
The logical board is not the actual board but the abstract concept of the board. The logical boardis composed of the actual boards whose functions are similar. The logical board is used for dataconfiguration and alarm output. This is to facilitate the operation to manage and maintain theconcrete boards belonging to the same type.
The physical board is the actual board, that is, the actual object of the logical board. Every logicalboard includes one or more physical boards. The physical boards belonging to the same logicboard are different in terms of interfaces, performance and location.
The same physical boards can back up in master and slave mode or in load-sharing mode.
For different physical boards, the backup mode differs. Some boards can only adopt the masterand slave mode; some only the load-sharing mode. Some boards can adopt either mode. Notethat only one mode can be adopted at one time.
To work in the master and slave backup mode, two boards need to be inserted in paired slots.
The following slots are paired slots: slot 0 and slot 1, slot 2 and slot 3, slot 4 and slot 5, slot 10and slot 11, slot 12 and slot 13, and slot 14 and slot 15.
Some boards whose positions are fixed do not need to be inserted in paired slots when the masterand slave mode is adopted. For example, boards such as the OMU, TNU, CLK need to be insertedin fixed slots.

NOTE
Figure 3-1 and Figure 3-2 only show the connections between backplane buses and boards, rather thanslots positions. The front boards and back boards are different in height. Therefore, front boards cannot beinserted into the rear backplane or back boards cannot be inserted into the front backplane. Some boardshave to be inserted in fixed slots. For information about board positions, see the specific description ofeach board.
3.4 Signal Streams Between Boards
Gateway Control Signal Streams
The gateway control signals are used to interact with an MGC and control various serviceresources of the media gateway (MGW). For the UMG8900, the gateway control signals workbased on the H.248 protocol.
The SSM-256 single-frame networking is taken as an example. The HRB is used for centralizedforwarding and the independent CMU is used to explain the H.248 message, extract the specificH.248 command and control the boards of the service resource and bearer resource.
Figure 3-3 shows the gateway control signal processing of the UMG8900.

The processing path of gateway control signal streams is:
The MGC sends the gateway control signals → IP interface board →HRB→CMU → mediaresource processing board (VPU) → service bearer board TNU/HRB/ASU → CMU (theexecution result returned from the media resource processing board) → HRB → IP interfaceboard →MGC

Call Control Signal Streams
The call control signal stream refers to the call control signaling used in the service connectionprocess. The UMG8900 supports the embedded signaling gateway (SG) to adapt and transferthe call control signaling. The UMG8900 supports the common channel signaling and channelassociated signaling (CAS). The CAS supported by the UMG8900 mainly includes R2, CNo.1,and No.5. The supported common channel signaling includes the SS7, DSSI, and V5 protocol.
The UMG8900 implements the adaptation processing and forwarding from the TDM to IP packetand adopts the SIGTRAN protocol.
The SPF of the UMG8900 implements the adaptation processing of the common channelsignaling. In addition, the SPF parses the messages of the transmission layer at the narrowbandTDM side and implements adaptation at the IP packet side.
The SSM-256 single-frame networking is taken as an example. Suppose that the upstream IPpacket interface provided by the HRB is used to transfer the SS7 signaling based on the M2UAmode.
Figure 3-4 shows the transfer path of the SS7 signaling.

The adaptation and transfer path of the SS7 signaling is:

Service Bearer Signal Steams
The service signal streams refer to the processing flows for bearer services in the UMG8900.The service signal streams also include the processing flows of service resources in the serviceconnection process.
The SSM-256 single-frame networking in TDM<->IP bearer application is taken as an example.Figure 3-5 shows the processing flow of service bearer data streams.

TDM: time division multiplexing GE: gigabit Ethernet
In the TDM<->IP mode, the processing flow of the service bearer signals is:
l For the signal stream input from the TDM side
Input of TDM signals → TDM interface board → TNU → VPU → HRB → IP interfaceboard →Output of packet signals
l For the data packet input from the IP side
Input of packet signals → IP interface board → HRB → VPU → TNU → TDM interfaceboard → Output of TDM signals
Related explanation is as follows:
l Different bearer services in the packet mode need to be forwarded through the packetswitching network provided by the NET.
l The TDM interface board can be the E32, T32 or S2L. The IP interface board can be theE8T, E1G, P1H or P4L.
l The service flow between the HRB and its back interface board is not transmitted throughthe backplane bus. Instead, the front HRB connects with its back interface board directly.
l The service resource board is the VPU.

This mainly describes the service processing flow in single-frame mode. In multi-frame cascading mode,the cascading boards are used to provide the service processing flow between frames.
Operation and Maintenance Signal StreamsThe operation and maintenance signal streams refer to the processing flows of various operationand maintenance signals during the operation, maintenance and management. The operation andmaintenance signal stream of the UMG8900 includes the OMC signal stream, alarm signalstream, and board-loading signal stream.
The OMC signal stream sent through the LMT is taken as an example. Figure 3-6 shows theprocessing flow of the operation and maintenance signal streams.

The processing flow of the OMC signals is:
Service board → MPU in the same frame → OMU in the main control frame → LMT operationand maintenance system/network management system
NOTE
For the service board in the main control frame, the OMC signals are directly reported to the OMU in thesame frame.
The previous part describes the signal streams between boards in sample service flow of theUMG8900. For details on signal streams, see the HUAWEI UMG8900 Universal Media GatewayProduct Description.
3.5 Common Characteristics of Boards
The UMG8900 boards contain maintenance bus (MBus) modules. The MBus module of a serviceboard communicates with the main control board in the same frame through the controller areanetwork (CAN) bus. The main control board is responsible for board version management, statusquery, board power-on/off control, reset, serial port communication, environment monitor, alarmmanagement and so on.
All boards are hot swappable. Each board has a hot pluggable indicator OFFLINE on its frontpanel and a hot swap switch under its ejector lever. When a board is inserted into a frame andthe ejector levers snap in place, the hot swap switch is on. When the ejector levers are removed,the switch is off and the hot swap indicator lights up. This indicates that the board can beremoved.
The power consumption of the board of the UMG8900 turns to heat, that is, the powerconsumption and heat dissipation are in the same level.

5.1 MNETThis describes the functions, panels and structures, indicators, interfaces, DIP switches andjumpers, fuses, and technical specifications of the MNET.
As the packet switching unit of the UMG8900, the master and slave MNETs are inserted in backslots 7 and 8 in the frame. The MNET can be inserted only in SSM-256 frames.
The MNET provides the following functions:
l Providing packet service switching channels in a frame to exchange service data betweenpacket service boards in the frame
l Cascading two frames to realize the cascading function between frames. The embeddedcascading module in the board enables interworking of 2 x GE service data planes andinterworking of 2 x FE service control planes
l Providing service control and maintenance interfaces for the corresponding front boardssuch as the MOMU or the MMPU to meet back cabling requirement
l Receiving clock signals from the MCLK, and sending them to TDM service processingboards after phase lock, signal driving and distributingThe internal clocks synthesized and distributed by the MNET are as follows:– 32.768 MHz clock: TDM HW synchronous clock signals for the TDM bearer processing
– 38.88 MHz clock: TDM SDH synchronous clock, including the synchronous clockrequired by the ATM and POS services in the SDH transmission mode
– 2 kHz clock: TDM SDH frame clock
The TNU, E32, T32, S2L, S1L, TCU, BLU, SPF and ECU use 32.768 MHz, 38.88 MHzand 2 kHz clock signals. The A4L and P1H only use the 38.88 MHz clock signal.For details on system clock, see the HUAWEI UMG8900 Universal Media GatewayProduct Description.
The MNET falls into two types: the UG01MNET and UG02MNET. The difference betweenthem is as follows:
l The UG01MNET provides 16 GE cascading capacity, and the UG02MNET provides 24GE cascading capacity.
l The FE interfaces on the UG01MNET board include FE0 and FE1. The FE interfaces onthe UG02MNET board include FE0, FE1&FE2, and FE3&FE4. The function of FE0interface is same as that on the UG01MNET. FE1&FE2 and FE3&FE4 interfaces arecascading network interfaces which can provide four cascading network interfaces byextended network cables.

5.5 MTNCThis describes the functions, panels and structures, indicators, interfaces, DIP switches andjumpers, fuses, and technical specifications of the MTNC.
The MTNC is the TDM central switching unit of the UMG8900. The master and slaveMTNCs are physically inserted in back slots 7 and 9 in the main control frame and the serviceframe; however, they are logically configured in slots 7 and 8. Each MTNC occupies two slotsand all the MTNCs occupy slots 6 to 9. The MTNC can only be used in the SSM-32 frame.
The MTNC provides the following functions:
l The MTNC can manage the TDM service switching. The MTNC is the TDM serviceswitching unit. It provides 32 K timeslot switching capability and provides 1 K or 2 Kswitching capacity for each interface board.The UG02MTNC provides 96 K timeslotswitching capacity and provides 1 K, 2 K, or 4 K switching capacity for each TDM interface.The UG02MTNC supports the UG02MS2L and UG02MECU.
l The UG01MTNC2 provides one TDM cascading link and the UG01MTNC5 provides twoTDM cascading links. If the TS1C, TS2C, or TS4C subboard is installed on theUG02MTNC, the UG02MTNC can respectively provide one, two, or four TDM cascadinglinks. The interfaces connect with the corresponding frames through the optical fibers. Eachcascading interface provides 8 K timeslot switching capacity.
l The MTNC is the switching center of the control plane, exchanging the message amongall boards in the control plane.
l The MTNC provides three FE cascading links, exchanging the control message betweenframes.
l The MTNC provides 8 KHz stratum-3 clock through the stratum-3 clock subboard.
l The MTNC receives 16 KHz stratum-2 clock provided by the stratum-2 clock board andgenerates the clock required by the system.
l The MTNC can deliver 8 KHz clock through the cascading path between frames, deliveringthe system clock.
l The MTNC provides device management function. Besides the communication with all theboards through the control plane, the MTNC can also implement board informationmaintenance, power-on management and exceptional situations handling through theindependent MBus maintenance path.
The MTNC falls into two types: UG01MTNC and UG02MTNC. The UG02MTNC is compatiblewith the UG01MTNC. When the UG02MTNC and the UG01MTNC are used at the same time,

Issue 05 (2009-01-09)
all the functions of the UG01MTNC can be realized. When the UG02MTNC and theUG02MTNC are used at the same time, 96 K TDM switching capacity and a maximum of 4 x8 K TDM cascading capacity are available. Other functions are the same as those of theUG01MTNC. The silkscreen on the panel of the UG02MTNC is MTNCb.
The UG01MTNC falls into two types: UG01MTNC2 and UG01MTNC5. The differencebetween two types is that the UG01MTNC2 provides one TDM cascading optical port and theUG01MTNC5 provides two TDM cascading optical ports.
The UG02MTNC contains the UG02MTNC1, UG02MTNC2, and UG02MTNC4 and theyprovide one, two, and four TDM cascading ports respectively.

As the front cascading board in multi-frame cascading application, the MFLUs are inserted infront slots 0 to 5 and 10 to 15 in the central switching frame. The MFLU can be inserted onlyin SSM-256 frames.
The MFLU provides the following functions:
l The UG01MFLU forwards 1 x 8K TDM cascading data sent by the MTNU to theUG01MBLU in the back slot and the UG01MFLU forwards 2 x 8K TDM cascading datathrough the backplane. Therefore, the total TDM cascading capacity is 3 x 8K.
l The UG02MFLU forwards 2 x 8K TDM cascading data sent by the MTNB to theUG02MBLU in the back slot and the UG02MFLU forwards 2 x 8K TDM cascading datathrough the backplane. Therefore, the total TDM cascading capacity is 4 x 8K.
l Two MFLU provide 2 x 1.25 G GE data cascading channels for the MBLU in the back slot.
The MFLU falls into two types: the UG01MFLU and UG02MFLU.
The major differences between the UG01MFLU and the UG02MFLU are as follows:
l The UG01MFLU can work with only the UG01MBLU and the UG01MTNU.
l Functions of the G02MFLU are the same as those of the UG01MFLU; however, theUG02MFLU can work with only the UG02MBLU.
l The UG02MFLU provide one more ACT indicator than the UG01MFLU. The namesilkscreen of the front panel on the UG02MFLU is MFLUb, while that on theUG01MFLU is MFLU.
The UG01MFLU is not described.

11.1 MS2LThis describes the functions, panels and structures, indicators, interfaces, DIP switches andjumpers, fuses, and technical specifications of the MS2L.
As the TDM service interface board, the MS2Ls are inserted in back slots 2 to 5 and slots 10 to15 in the main control frame, and back slots 0 to 5 and slots 10 to 15 in the service frame. In theSSM-32 frame, if the clock subboard of the MTNC provides the system clock, then the MS2Lcan be inserted in any slot of back slots 0 to 5 in the main control frame. The MS2L can workin master and slave backup mode or load-sharing mode.
The MS2L provides the following functions:
l Extracting clock signals and forming frames at the two 155 Mbit/s SDH optical interfaces;providing interfaces with pluggable optical modules enabling different transmissiondistances
l Processing overheads of regenerator section and multiplex section of optical signals andchecking communication over optical channels
l Implementing SDH mapping, de-mapping and processing overheads of high-order pathand low-order path
l Forming 2 x 63 E1 or 2 x 84 T1 frames and performing DS0 switch
The MS2L falls into two types: the UG01MS2L and UG02MS2L. The difference between twotypes is as follows:
l The UG01MS2L can be used only in the SSM-256 frame.
l The UG02MS2L can be used in the SSM-256 frame and the SSM-32 frame. The silkscreenon the ejector level of the UG02MS2L is MS2Lb.

l All optical fiber interface boards are identical in appearance. They use different optical modules. Youcan query the optical module type of a board with LST OPTINFO.
l The receiving power of the optical module must be greater than the maximum receive sensitivity andless than the saturation optical power. Excessively low receiving power may cause bit errors, whichdestabilizes the service. Excessive receiving power may cause damage to optical modules.
11.2 MS2EThis describes the functions, panels and structures, indicators, interfaces, DIP switches andjumpers, fuses, and technical specifications of the MS2E.
As the time division multiplex (TDM) service interface board, the MS2Es are inserted in backslots 2 to 5 and slots 10 to 15 in the main control frame, and back slots 0 to 5 and slots 10 to 15in the service frame. In the SSM-32 frame, if the clock subboard of the MTNC provides thesystem clock, then the MS2E can be inserted in any slot of back slots 0 to 5 in the main controlframe. The MS2E can work in the master and slave backup mode or the load-sharing mode.
The MS2E provides the following functions:
l Extracting clock signals and forming frames at the two 155 Mbit/s SDH electrical interfaces
l Processing overheads of regenerator section and multiplex section of optical signals andchecking communication over optical channels
l Implementing SDH mapping, de-mapping and processing overheads of high-order pathand low-order path
l Forming 2 x 63 E1 or 2 x 84 T1 frames and performing DS0 switch
The MS2E falls into two types: UG01MS2E and UG02MS2E. The difference between two typesis as follows:

Application Scenario
The 75-ohm E3/T3 trunk cable is used to transmit E3/T3 signal.
The UMG8900 adopts two types of E3/T3 trunk cable. Both of the two types are the coaxialcable with the impedance of 75 ohms and adopt the BNC connector. However, the number ofconnectors of the two types of trunk cables are different. For the first type, one end has the BNCconnector and the other end has no connector. For the second type, both ends have the BNCconnectors and T-shaped conversion connectors.
When the PIE works in load-sharing mode, the E3/T3 trunk cable with one BNC connector isadopted. When the PIE works in master and slave mode, the E3/T3 trunk cable with two BNCconnectors are used to collect the signals on the mater and slave boards. Then the E3/T3 trunkcable with one BNC connector is used to transmit the signals.
