Establish DS3 or EC-1 service

Procedure 10-3: Establish DS3 or EC-1 service

Overview

Use this procedure to establish end-to-end DS3 or EC-1 service.

Important!

This procedure assumes that the Alcatel-Lucent 1665 DMXtend shelf and network have been properly equipped and tested. If the Alcatel-Lucent 1665 DMXtend shelf has not been properly equipped, refer to Chapter 5, Node turnup procedures. If the network has not been properly configured, refer to Chapter 9, Network configuration procedures.

Privilege level

You must login as either a Privileged or General user to complete this procedure.

Before you begin

Prior to performing this procedure:

Refer to Before you begin and Required equipment in this chapter.
Refer to Electrostatic discharge in Chapter 1, Safety.
Obtain the work instructions for this procedure.
Verify that the work instructions specify the terminating nodes, pass-through nodes (UPSRs only), DS3/EC-1 port addresses, the DS3/EC-1 port parameters to provision, and the cross-connections to be established.

Steps

Complete the following steps to establish end-to-end DS3 or EC-1 service.


1	Click the Alarm List button to obtain an NE Alarm List and verify that no alarms are present. Clear all alarms before continuing this procedure. Reference: Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Alarm Messages and Trouble Clearing Guide, 365-372-326
2	At the terminating nodes, select View → Equipment to verify that the proper service and protection DS3/EC-1 circuit packs have been installed in the Function Unit group (A/B, D, or G) used for this service.
3	If circuit packs have not been installed, install circuit packs as required. Reference: Procedure 4-6: Install DS1/DS3/16/3 circuit packs Procedure 4-7: Install DS3/EC1 circuit packs
4	At the terminating nodes of the circuit being established, determine which DS3/EC-1 ports are to be put into service and what port parameters to provision using the work instructions.
5	At the terminating nodes, select Configuration → Equipment. Expand the required circuit pack details, then select the DS3/EC-1 port to provision for the circuit being established. Provision parameters as required. If the Port Monitoring Mode is provisioned to NMON, the port is not monitored/alarmed and the port will not automatically transition to the IS (in-service) state when a good signal (not LOS) is detected. If the Port Monitoring Mode is provisioned to AUTO, the port automatically transitions to the IS (in-service) state when a good signal (not LOS) is detected, and the port is monitored/alarmed. If the Port Monitoring Mode is provisioned to IS, the port is monitored and alarms are reported. Reference: Procedure 4-8: Provision DS3/EC1 circuit packs/ports for service
6	Verify that the DS3/EC-1 cable connections have been made from the terminating nodes to the cross-connect panel or equivalent connection points.
7	Determine the necessary add/drop and pass-through (UPSRs only) cross-connections for each node from the work instructions.
8	At the terminating nodes and pass-through nodes (UPSRs only), select Configuration → Cross-Connections to access the Cross-Connection Wizard and establish the necessary cross-connections. Use the following references as examples. Reference: Procedure 10-5: Make VT1.5 or STS-n cross-connections, single OC-3/OC-12 UPSR configuration Procedure 10-6: Make Function unit UPSR, hairpin, and Main to Function unit UPSR cross-connections Procedure 10-7: Make 1+1 (linear extension) cross-connections Procedure 10-8: Make single-homed cross-connections Procedure 10-9: Make dual-homed cross-connections Procedure 10-11: Establish dual ring interworking (DRI) connections Procedure 10-12: Provision DS1/DS3 locked cross-connections on a UPSR Procedure 10-13: Configure LNW20 TMUX/DS3/EC1 applications
9	Perform the DS3/EC-1 end-to-end transmission test for each circuit being put into service, as required. Reference: Procedure 14-10: Perform DS3 transmission test Procedure 14-11: Perform EC-1 transmission test
10	Important! If the Port Monitoring Mode is provisioned to NMON, the port is not monitored/alarmed and the port will not automatically transition to the IS (in-service) state when a good signal (not LOS) is detected. If the Port Monitoring Mode is provisioned to AUTO, the port automatically transitions to the IS (in-service) state when a good signal (not LOS) is detected, and the port is monitored/alarmed. If the Port Monitoring Mode is provisioned to IS, the port is monitored and alarms are reported. At the terminating nodes, select View → Equipment to access the required DS3/EC-1 ports and verify the value of the Port Monitoring Mode parameter. If required, select Configuration → Equipment to access DS3/EC-1 ports and change the value of the Port Monitoring Mode parameter.
11	Important! If the Tributary Monitoring Mode is provisioned to NMON, the tributary is not monitored/alarmed and the tributary will not automatically transition to the IS (in-service) state when a good signal (not UNEQ, AIS, LOP, SF) is detected. If the Tributary Monitoring Mode is provisioned to AUTO, the tributary automatically transitions to the IS (in-service) state when a good signal (not UNEQ, AIS, LOP, SF) is detected, and the tributary is monitored/alarmed. At the terminating nodes and pass-through nodes (UPSRs only), select View → Equipment to access the required tributaries and verify the value of the Tributary Monitoring Mode parameter. If required, select Configuration → Equipment to access tributaries and change the value of the Tributary Monitoring Mode parameter. End of steps
