1+1 Hot Stand-By Protection Less than 50 mSec switching time Switching criteria – LOF, BER, External Master/Master, Master/Slave, Slave/Slave Scalable architecture

1+1 Protection

1 + 1 Hot Standby

The system is doubled on both Local and Remote ends

One unit on each end is active (“Master”) while the other

is standby (“Slave”) Master transmits and receives data

Slave only receives data

Inter-mate UART cable allows negotiating the mastery and data exchange between units

One or Two antennas per site

On a failure in an active unit or a command from the

remote side, Master Switch will occur (redundant unit

will take over activity)

Switching time: less than 50 mSec

Protected - What From?

1+1 configuration protects the main link from a

hardware or radio failure in one of the units on Local,

Remote, or both ends

Does not protects from coincident failures in both units

on the same end

Link self-recovery once failure cleared/corrected

No protection from fading

Link self-recovery once fading cleared

Protection Triggers

Wave-guide connector – PDR84 (PDR70 also available)

Available wave-guide:

Flexible wave-guide

Provided with each ODU (1.2m, 0.6dB loss)

Elliptical wave-guide (typical loss 30dB/100m)

Diversity basic concepts

Frequency Diversity

Uses the nature of frequency selectivity of the multipath dispersive

fading

Space Diversity

Two antennas vertically separated at the receiver tower so only one

of antennas is located in a power minimum

Angle Diversity

Based on slightly different angles of arrival of the indirect delayed

waves and the direct wave

Space & Frequency Diversity

A combination of the above frequency and space diversity techniques

MHSB and SD

FD and HD

Angle Diversity

Ceragon Advantage:

Hitless System Overview

Enhancement of the FibeAir 1528 Hot-Standby

Configuration

Hitless!!!

No errors during the switch

Errorless!!!

No errors to the user before the switch

Data of better quality is delivered automatically to the user

Receiver Modem’s parameters are used as criteria for

activating the switch.

Supports Space and Frequency diversity

Switching criteria

The modems of the two IDUs are connected using the

“Hitless Cable”

Primary

FEC-based decision to determine the path with no

errors

Secondary

Mean Square Error (MSE)

If both FECs detects errors, the path with less errors

will be selected

Using 20uSec buffer, no errors even before the switch

MUTE

XMTR A RCV A

XMTR B RCV B

Data outData in SpaceSeperation

One transmitter is used, the other in MUTE mode

The receivers are connected to two antennas physically

spaced apart (100’s of wavelengths)

The spacing determines the delay between the two

receivers

The physical separation should be 3-30m (based on the

requested improvement factor

Typically, 6-15m

Space Diversity

XMTR A RCV A

XMTR B RCV B

Data outData in

F1

F2

Two transmitters are used, both in normal operation

connected to one antenna (with splitter) or two antennas

The two receivers are connected to one antenna (with

splitter) or two antennas

The frequency determines the separation between the

two receivers

DFM is frequency-dependant therefore using two

frequencies (the farther they are - the better)

Frequency Diversity

Both solutions protects against fading and H/W failures

FD is more expensive solution –

two channels are required!

SD is more effective – improvement is more significant!

Management – IP Configuration (2)

Transport element management information

seamlessly and simply throughout the network

In-Band Management

Management information is carried in the SONET/SDH

frame (over the Radio and over the Line)

Full management solution: can carry management

information of any IP-based external equipment

Topologies:

Rings

1+1 Hot-Standby

Cascaded links and more…

The Solution

Most efficient

SONET/SDH and ATM networks

Management network transparent within the OC-3 / STM-1

Line

Important! External equipment must not alter the DCCr bytes!

1. DCCr to Radio and Line

Management is transmitted only to the Radio side

SONET/SDH, ATM and IP networks

Does not rely on ADM processing of DCCr bytes

Simple cross-over Ethernet cable used to connect

management at each site

2. DCCr to Radio Only

Allows management of external equipment (such as

ADMs, Switches, other radio equipment…)

Management information to the rest of the network is

directed to the management Ethernet port and then to

the HUB

ExternalEquipment

ExternalEquipment

Managing External Equipment

The IDU checks each received IP packet:

Destination IP address of packet = IP address of IDU

IDU will pass packet to its own IP port for further Processing

Destination IP address of packet IP address of IDU

If packet arrived from within the ring Sent to the other

side of link

If the other side of the link is down, packet is returned to its

originator

If packet arrived from outside the ring or from the IDU itself

Packet is sent to the radio side

If radio side is down Forward to the line side

How Does It Work?

Basic IP Theory

IP Address : 192.168.1.139 (dec) =

1100 0000 . 1010 1000 .0000 0001 . 1000 1011 (bin)

Mask: 255.255.255.240 (dec) =

1111 1111 . 1111 1111 . 1111 1111 . 1111 0000 (4 zeros mask)

IP addresses on the same sub-net:

1100 0000. 1010 1000 . 0000 0001 . 1000 0000 (192.168.1.128) to

1100 0000. 1010 1000 . 0000 0001 . 1000 1111 (192.168.1.143)

The last 4 bits cannot be all zeros or all ones

192.168.1.128 and 192.168.1.143 are not available!

IP - Example (1)

Ring IP Address: 192.168.1.0 Mask: 255.255.255.240

IP addresses on the sub-net: 192.168.1.0 to 192.168.1.15

IP addresses that can be used: 192.168.1.1 to 192.1.14

Trouble-shooting Using Alarm Log

Check current alarm (!!!)

Identify when alarms started

Identify separate events based on time

Check correlation with other links failed

Check correlation to RSL to explain alarms

Check correlation to Radio/Line SDH PM

RSL Monitoring

Trouble-shooting Using RSL

Check current RSL

Check changes in RSL during last 24hours (5dB

change during the day is normal)

Identify rain fading, multipath/ducting

Check if RSL reached sensitivity threshold

In case of ATPC, check Transmit Signal Level

Trouble-shooting Using PM

Always check Radio and Line PMs

Check alarm log for correlation

Check correlation to RSL to explain errors

Loop-back Configuration

Trouble-shooting Using Loop-backs

If problem currently exists:

Use Line loop in case of LOS, LOF or Errors on STM-1

input of IDU or external ADM

Use IF loop in case of LOF or BER on Radio to identify

if IDU is OK

Use ODU loop in case of LOF or BER if IF loop passed

OK (available 7-8GHz ODUs only!)

Synchronization Sources

FibeAir 1500A/1528A is compliant with G.813

Synchronization Sources:• External • Aggregate East / Aggregate West• Tributary• Internal (accuracy 4.6 ppm [BER 10-6] SEC or Stratum-3)

Note: For each Network Element can be configured two possible clock sources: primary & secondary

When both sources are lost, an appropriate alarm will be reported and the ACTIVE source will be “no source” - Hold Over mode.

Synchronization Strategy (1)

SSM MODE

Utilization of S1 (Timing Marker) byte

The SSM informs the neighboring NE about the status of the clock

supply

The S1 byte is used to select the best timing source for the NE and

to prevent timing islands

Assignment of timing source quality level to each NE

Timing Generator (TG) source selection ‑ Enables the user to

configure two possible clock sources for each NE

For each timing source the user assigns a quality level

If both clock sources fail, the NE switches to Hold-Over mode

Synchronization Strategy (2)

SSM Disabled

Definition of Primary and Secondary clock sources for each NE

If the Primary clock source fails, the NE will switch to Hold-Over

mode

In this case alarm will be generated “Clock Unit Unlocked” and the

user can select and switch manually to the Secondary or Internal

clock source

With no active clock source, the NE will remain in Hold-Over mode

for 48hours, and then will switch to Internal clock source

Once the Primary clock source is restored, the NE will switch

automatically to the active clock source

Timing source quality levels

Quality Level Description

High 1 G.811 - atomic source

2 G.812 - Transit

3 G.812 -Local

4 Unknown (PDH Sync)

5 Internal G.813 clock

Low 6 Don't use for Sync

First of all - Plan!

1. Sketch the general configuration

2. Design the radio links

3. Define Radio Side direction (East or West) for each NE

4. Define the Tributaries path (physical port, VC-12, mapped

trial, transparent trail, active path) for each NE

5. Define Main and Secondary paths for protection

6. Define the synchronization sources for each NE

7. Design the in-band management and IP addresses
