Service-Affecting Actions 8
Although the DDM-2000 OC-3 Multiplexer is designed to minimize loss of service
due to equipment failure or human action, there are certain controller related
actions that can cause a loss of provisioning data and possibly loss of service.
These actions include:
■ Replacing a transmission circuit pack when the SYSCTL is failed or
removed can result in a loss of provisioning data and loss of service
■ Replacing a transmission circuit pack in a shelf without power can result in
a loss of provisioning data. Loss of service may continue on channels
associated with the replaced circuit pack after the shelf is powered up.
■ Executing the command init-sys:all sets all provisioning data,
including cross-connect provisioning, to default values. This causes loss of
service on any channel connected with non-default cross-connections.
■ Failing to disable the SYSCTL circuit pack before it is removed in
accordance with TOP procedures could result in unexpected events;
however, no loss of service occurs. Refer to the "Install or Replace
SYSCTL" procedure in the TOP section of this manual (Volume II).
■ Provisioning data is maintained through a software download to the
SYSCTL. Replacing the SYSCTL circuit pack with incompatible software
and intentionally overriding the software check could result in a loss of
service.
