Benefit

Being able to deploy Connect DX nodes on existing DWDM (OC-192/TN-64Xbased) or OPTera LH networks (re-using same regen and line amp sites)

A to Z ring wide provisioning/connection management, so rings composed ofmixed NE type could be supported (e.g. OPC-192 4-F ADM and Connect DX 4-FADM). It is key to be able to deploy a 4-F Connect DX in an existing 4-F ring atkey locations where additional Add/Drop or hub functionality is required.

OPTera Connect DX1Network Level Traffic Switching in 2FR

One half of the 10G bandwidth available between adjacent nodescan be used for working traffic, with the remainder reserved for

protection.

The bandwidth partitioning is accomplished by mapping trafficinto channels (time slots) 1 through 96/SONET or 1 through

32/SDH ( the working channels) for OC-192/TN-64X applications.

If a Ring Protection Switch needs to be performed, traffic gets re-directed by looping back time slots away from the fault. The

working channels, 1 through 96/SONET or 1 through 32/SDH, get

mapped onto the protection channels, 97 through 192/SONET or

33 through 64/SDH, respectively on the fibers going in the

opposite direction.

Time slot bridging only occurs at the nodes adjacent to the faultwith intermediate nodes simply passing through the re-directed

traffic back around the ring.


37/53

39



OPTera Connect DX12-FR Network Reconfigurations

Add/Delete Nodes Adding an NE to ring requires a Forced Ring Switch to be

applied to each of the adjacent nodes.

With Forced Ring Switch the protection bandwidth will be

occupied, thus some disruption to the BLSR operation of the

network will result.

As for 4-FR configuration, the NE will operate as Full

Passthrough on both the Protection and the Working lines

when in forced state. Full APS channel (K-Byte) Passthrough

is also forced.

Synchronization Status Messaging

I d i B i T i l


39/53

41



Introduction: Basic Terminology

BITS: Building-integrated timing supply provided to the NE froman external clock source. The external source is 1.544Mb/s DS-1

for SONET, or a 2MHz for SDH.

ESI: Circuit pack located in the Control Shelf, (a) provides a DS1or 2 MHz reference output (b) provides an output timing signal to

Switch card based on available timing references. Two ESI cardsprovide 1+1 redundancy.

SSM: Synchronization Status Messaging, providing timingreferences based on quality of available timing sources.

TG: Timing Generation group CLUI menu in NE, indicating state ofBITS and line timing sources.

TD: Timing Distribution group provided from line optics to SATTfor timing output references (G1OUT & G2OUT). Provisionable at

CLUI level.

Wh t i SSM?


40/53

42



What is SSM?

Software functionality within NE that extracts/inserts S1 byte ofincoming/outgoing OC-N/STM-N and DS-1 signals.

Bits 5 to 8 (S1 byte) of the SONET overhead are read andmanipulated according to GR-253-CORE

Provides automatic switching to the most suitable timing referencebased on reference quality and priority.

Offers timing intelligence, reliability in network synchronization.

At NE1 and NE5, BITStiming produces ST1

transmission on all line

As shown in building

blocks, a line-timed NEtransmits ST1 away from

the source, and transmits

DUS back to the source.

If the ADM ring is 4-FRinstead of 2-FR, the same

QC is transmitted on thewest/east bound direction

and discovers there are

none available. NE2 switches timing mode

NE3 compares ST3 fromNE2 to DUS from NE5, and

Provisioning Requirements

Q: Are timing loops now eliminated? A: NO.

The user may still inadvertently provision a QC override that

prevents the ESI from selecting the best timing source.

The user may also provision a BITS-timed NE to include both

BITS and line timing (currently done on OC-192/TN-64X !).

Q: Can timing loops be prevented entirely? A: NO !

If there is lost BITs sources in the network or fiber cuts, it is

possible to get timing loops.

Q: What is the best way to prevent timing loops?

A: Keep QL override for Rx & Tx to AUTO, so that SSMis allowed to work.

User Considerations for DX1 SSM

Engineering Rules:

SSM is only supported on DX and TN-64X bays.

- OC-192 bays will not support SSM. Mix of OC-192 bays with DX will need to

have SSM disabled.

- Mix of DX and TN-64X bays supports SSM.

Both SONET and SDH SSM are supported but not at the same time.

Upgrades:

Upon NE upgrade to software which supports SSM, the NE will begin to

read the incoming S1 byte, employ the SSM algorithm and writing the

S1 byte.

QC will take precedence over TG priority.

SSM may be disabled by setting QC override to STU (forcing the NE to

use priority levels).

Tributaries:

The OPTera DX cannot receive timing from tributaries (under

consideration for a future release)

NEs which exist in a configuration, but which are not part of the OPCs

SOC, will be assumed to be OC192/TN64X NEs, and their G-numbers

will be displayed as such, regardless of the actual type of the NE.

Each OPTera Connect DX SOC can manage either SDH

or SONET types, but not both The OPC Connection manager will allow the user to provision, modify,

and delete cross-connects on OC-192 and STM-64 ring and chain

systems.

MCS supports different NE loads on one OPC for multipleNE types Selection of Catalog file is based on NE type

OPTera DX1 SOC Deployment Guidelines

Primary OPC and backup OPC are required for each SOC

Primary and Backup OPCs should be in differentlocations

Network size beyond the 150 node limit will require Level

2 routing Maximum of 34 elements within same SOC

Maximum of 30 datacomm hops between primary OPC toa managed NE

Maximum of 4 concurrent INM workstations

OPTera Connect software OPCs may be located inexisting 10Gb/s bays (OC-192/TN-64X).
