Suspend OC-12 1+1 to OC-48 1+1 upgrade (single-rate circuit packs)

Procedure 12-24: Suspend OC-12 1+1 to OC-48 1+1 upgrade (single-rate circuit packs)

Overview

NOTICE

Service-disruption hazard

If a node has been taken out of the Ring Upgrade Mode, the node cannot be returned to the original pre-upgrade state without affecting service.

All nodes connected to the 1+1 network using the Main slots must be in the provisioned Ring Upgrade Mode.

Important!

This procedure starts at the last node upgraded. The last node upgraded must be connected to the 1+1 network using the Main slots. Suspending an upgrade at a node connected to the 1+1 network using port pairs in the Function/Growth slots is not supported.

This procedure assumes that the last node upgraded is a Alcatel-Lucent 1665 DMXtend.

Use this procedure to temporarily suspend an OC-12 1+1 to OC-48 1+1 upgrade where the near-end and far-end nodes are connected to the 1+1 network using single-rate circuit packs in the Main slots.

To temporarily stop the upgrade at a Alcatel-Lucent 1665 DMXtend node connected to the 1+1 network using multirate circuit packs in the Main/Function/Growth slots, refer to Procedure 12-27: Suspend UPSR/1+1 upgrade at node (multirate circuit packs).

Suspending an upgrade in progress temporarily stops the upgrade.

To return all nodes in the 1+1 network to their pre-upgrade state, refer to Procedure 12-23: Back out OC-12 1+1 to OC-48 1+1 upgrade (single-rate circuit packs).

When the 1+1 upgrade is temporarily suspended before completion, one span is operating at the OC-12 line rate and the other span at the OC-48 line rate. This requires that the near-end and far-end nodes be equipped with an OC-12 OLIU circuit pack in one Main slot and an OC-48 OLIU circuit pack in the other Main slot. These nodes must be connected to the 1+1 network using the Main slots. Suspending an upgrade when a node is connected to the 1+1 network using port pairs in the Function/Growth slots is not supported.

To continue to operate temporarily with different circuit packs in the Main slots, the near-end node (starting node) and the far-end node must remain in the Ring Upgrade Mode.

Privilege level

You must log in as a Privileged user to complete this procedure.

Required equipment

The following equipment is required to perform this procedure:
