1. INTRODUCTION This EMoP details the steps required to implement the VTN 40G Expansion & Upgrade, Ring 1. This project consists of the following activities:

1. DWDM backbone reconfiguration: a. Convert of Thanh Hoe site from LineAmp to Regen site. b. Increase the capacity of Ring-1 LH backbone with 2x10G lambdas. c. Decrease the capacity of Ring-1 LH backbone by 8x2,5G lambdas.

2. 2x10G 2F--BLSR/MS-SPRing deployment. 3. Migration of traffic from the in-service 8x2.5G UPSR/SNCP rings to the new 2x10G 2F-

BLSR. These activities will be executed in three maintenance windows (MW) as follows:

1st MW, Pre-checks: a. Validation of network status. b. Validation of I&C practices. c. Inventory of equipment and material required in this reconfiguration

2nd MW, Main Activities: d. LH reconfig. e. 2x10G 2F-BLSR line up. f. Traffic Migration.

3rd MW Post-Checks. g. Verify the in-service network status h. Submit the Service Completion Notice

In summary, the main procedure shall start with a path protection switch between Hanoi-NE20000 and Vinh-20001 against all circuits provisioned in the 2.5G circuit packs (CP) connected the Upper DWDM link (Hanoi-NinhBinh ThanhHoa-Vinh). At this point, traffic will be active in the Lower DWDM link (Hanoi-HungYen-NamDinh-ThanhHoe2-Vinh). Next, LH-10003 will be converted to a TERM site and connected to a new DX bay (NE 20007-G0/G10 e/w 1554.94nm optics) and a new LH Regen bay (NE 10063-G2/G3 e/w 1547.72nm optics). This reconfig will result in the splitting of the upper link into two links: (a) Hanoi-NinhBinh ThanhHoa and (b) ThanhHoa-Vinh. After equalizing both of the resulting upper links, the 2x10G 2F-BLSRs will be provisioned (a Lockout of Protection (LoP) may be required on each 10G CPG). Subsequently, traffic from the 8x2.5G UPSRs will be rolled over the newly provisioned 10G 2x2F-BLSRs (previous release of the LoP). After traffic continuity is verified by the customer surveillance team (NOC), the existing Lower DWDM link will be reconfigured in a similar manner.

b. The new LH RPT bays in Thanh Hoa (NE10063 and NE10055) must be already installed, commissioned, and provisioned.

c. LH NE10063 and NE10055 must be running at the same SW release as the OPC to have control over it.

d. Thanh Hoa NE10003 OTR CPG G5 must be equipped, provisioned, and, if possible, connected to their respective DWDM couplers and DSCM modules, etc. This OTR CPG may be set to OOS (both equipment and facilities) afterward.

i. Tx/Rx power as per Nortel specification.

ii. Zero PM events reported in a monitoring period of 30 minutes.

f. The passive bays in Thanh Hoa site must be already installed.

g. The insertion losses of the DWDM couplers and DSCM modules, etc., must be already verified to comply with Nortel specifications.

h. All ports in the new DWDM couplers must be equipped with optical terminators.

i. All optical patchcords must be properly installed and tested.

j. All optical connectors and attenuator pads must be inspected, insertion-loss tested, cleaned, and protected with plastic caps.

2. The in-service DWDM links affected by this reconfig must meet the following pre-requisites:

a. Span losses shall not be greater than 0.3% of the estimated in the OPNET reports.

b. Minimum span losses must be 17 dB.

c. MSA losses must obey the 10 dB rule. No MSA loss outside the range (8, 11) dB shall be considered acceptable.

d. Every DWDM link must be properly equalized.



e. All LH amplifiers and repeaters must be free of unexpected alarms.

3. The in-service DXes and OM4Ks affected by this reconfig must be:

a. Running at the same SW release as the OPC/EMS that controls them.

b. Free of unexpected alarms.

c. Free of unexpected protection switches.

d. Zero PM events for at least half an hour before the reconfig starts.

4.2 General Engineering Rules

1. All installation, commissioning, and provisioning activities must be performed in accordance to Nortel Networks specifications as documented in corresponding NTPs, EDPs, and EMoPs.

2. Non standard traffic migration shall be performed by Nortel trained personnel only.

3. All DWDM link reconfigurations shall be implemented via an Out-Of-Service (OOS) mode. Note: A protection switch will prevent traffic impact during the OOS procedure.

4. Nortel Optical Networks Engineers shall consider their services completed successfully if the following criteria is met:

a. Traffic continuity is established for all circuit involved.

b. Zero facility PM events shall be reported by any circuit pack affected by this reconfig for a 30 minute monitoring period following the end of the main procedure.

c. Every DWDM link shall be equalized and their amplifiers provisioned (e.g., thresholds and general parameters) according to Nortel design documents and general technical recommendations.

d. The network shall be free of any unexpected alarms and protection switches.

4.3 System Impacts and Network Information

1) Path Protection Switches: < 50 ms.

2) Ring Protection Switches: < 50 ms.

3) Traffic Migration (best effort):

a) Expected in the order of hundreds of milliseconds (< 1 sec) per connection.

End of Procedure



8. APPENDIX

8.1 Back-Out Procedure

In the event an unexpected and persistent or alarm is observed in the network, the present reconfiguration should be aborted, and performing a back out procedure may be required in order to restore the network to its original condition.

1. If before traffic is migrated to the 2x10G 2F-BLSRs, Nortel ONE determines a back-out is required:

a. Re-provision the Upper link back to its original state. Use the data contained in the original network diagram and the information collected during pre-checks (see section 5.1.1).

b. Set the primary states of the facilities shown in section 7.1.2.7 to IS.

c. Reconnect the 2.5G CPs shown in 7.1.2.13 to their respective Mux/DeMux.

d. Re-equalize the Upper Link.

e. Monitor PM count for 15 minutes on all facilities referred to in step (8.1.4).

f. Release the path protection switch operated in step 7.1.1.2 and 7.1.1.5.

2. After traffic is migrated to the 2x10G 2F-BLSR, and before the Lower Link is reconfigured, if Nortel ONE determines backing out is necessary:

a. Re-provision the migrated cross-connects to their original 2.5G source and sink endpoints.

b. Perform steps 8.1.1.a to 8.1.1.f.

3. After traffic is migrated to the 2x10G 2F-BLSR, and the Lower Link is being reconfigured, if Nortel ONE determines backing out is necessary:

a. Re-provision the Lower Link back to its original state in a similar manner as in steps 8.1.1.a to 8.1.1.f.

b. Reconnect all 2.5G CPs transmitting and receiving through the Lower Link.

c. Monitor PM for 15 minutes on each 2.5G CP.

d. Operate a force switch against the 2.5G CPs that will interface the Upper Link.

e. Migrate traffic back to the original 2.5G CPGs.

f. Re-provision the Upper Link as per steps 8.1.1.a to 8.1.1.f.
