Procedure 10-1: Establish DS1 or E1 service

- Overview

Use this procedure to establish end-to-end DS1 or E1 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:

  1. Refer to Before you begin and Required equipment in this chapter.

  2. Refer to Electrostatic discharge in Chapter 1, Safety.

  3. Obtain the work instructions for this procedure.

  4. Verify that the work instructions specify the terminating nodes, pass-through nodes (UPSRs only), DS1/E1 port addresses, the DS1/E1 port parameters to provision, and the cross-connections to be established.

Steps

Complete the following steps to establish end-to-end DS1 or E1 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.

2

From the System View menu at each terminating node, select View → Equipment to verify that the proper service and protection circuit packs have been installed in the Function Unit groups (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 4-9: Install DS1/E1 circuit packs


4

At the terminating nodes of the circuit being established, determine which DS1/E1 ports are to be put into service, and what port parameters to provision using the work instruction.

Important!

All the ports on a DS1/E1 circuit pack are provisioned for either DS1 or E1; DS1 and E1 ports cannot be mixed on a single pack.


5

At the terminating nodes, select Configuration → Equipment. Expand the circuit pack details, then select the DS1/E1 port to provision for the circuit being established. Provision parameters as required.

The Bi-Polar Violations parameter does not apply to the LNW18/LNW20 TMUX circuit packs.

Bi-Polar Violations parameter value settings:

  • No - When Bi-Polar Violations is set to No (default), incoming BPVs at the DS1 port are corrected by the port unit circuitry before the DS1 is mapped into the VT1.5 payload and are not translated in the outgoing direction. This value should be used if not connected to a GR-8 compliant DLC.

  • Yes - Bi-Polar Violations should be set to Yes for a DS1 port connected to a GR-8 compliant DLC terminal. This permits the DLC system to detect LOS or LOF and switch to protection. If linecde=B8ZS, incoming bpv threshold crossings detected on the provisioned port will be translated to LOF before the DS1 is mapped into the VT1.5 payload. If linecde=AMI, incoming bpv threshold crossings detected on the provisioned port will be translated to LOS before the DS1 is mapped into the VT1.5 payload.

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.

6

Verify that the DS1/E1 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.

9

Perform the DS1/E1 end-to-end transmission test for each circuit being put into service, as required.

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 reported.

At the terminating nodes, select View → Equipment to access the required DS/E1 ports and verify the value of the Port Monitoring Mode parameter.

If required, select Configuration → Equipment to access DS1/E1 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.
