System Backup and Restoral 8
The CPro-2000 Graphical User Interface (GUI) and Provisioning Tool includes a backup
and restoral feature to protect provisioning information in ring networks. This feature
saves a copy of a node's provisionable parameters so they can be restored at a later date,
if necessary.
The feature provides backup and restoral for all provisionable parameters including:
■ Network Element (NE) provisionable parameters
■ Cross-connections
■ Port and line provisionable parameters
■ Performance Monitoring (PM) threshold parameters
Refer to Section 6, “Operations Interfaces,” of this manual for more information on
CPro-2000. See also 365-576-130, CPro-2000 User Manual, Release 7.0, for more
information on CPro-2000.
ITM SNC 8
All of the above backup and restore features are also available with the Integrated
Transport Management SubNetwork Controller (ITM SNC), Release 5.0. Refer to
107-564-270, Integrated Transport Management (ITM) SubNetwork Controller (SNC),
User Guide, for additional information.
Service-Affecting Actions 8
Although the DDM-2000 OC-12 Multiplexer is designed to minimize LOS due to
equipment failure or human action, there are certain controller related actions that can
cause a loss of provisioning data and possibly LOS. These actions include:
■ Replacing a transmission circuit pack when the SYSCTL is failed or removed can
result in a loss of provisioning data and LOS
■ Replacing a transmission circuit pack in a shelf without power can result in a loss
of provisioning data. LOS 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 LOS on any channel
connected with nondefault cross-connections.
■ Failing to disable the SYSCTL circuit pack before it is removed in accordance with
TOP procedures. Failure to follow the procedure could result in unexpected events;
however, no LOS 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 data.
