PRCDRERR-TOPO (Invalid topology)
In this release, the system enforces a rule that a valid cross connects must terminate on
one of the following end-points:
• a port marked as "External"
• a port marked as "No-connect"
• a transponder network port
In prior releases, there were no checks in place to prevent cross connects that do not
adhere to these rules. Therefore, if there are any cross connects already in place from a
previous release that do not adhere to the rules, this condition is raised on the NE in this
release after an upgrade from a previous release.
Services that are running over invalid cross connects may continue to operate, in which
case it may be best to wait for a maintenance window before performing this procedure,
or they may be interrupted, in which case a loss of service alarm is raised.
