Caveats
Changed Default Alarm Severities
The following alarm severities have changed for Release 4.1.x.
DDTS # CSCea81001
When a fault condition exists against a circuit or port that is in the OOS-MT or OOS-AINS state (or when
you are using the “Suppress Alarms” check box on the CTC Alarm Behavior pane), the alarm condition
is not assigned a reference number. If you were to place the circuit or port in service at this time, in the
absence of the reference number, the CTC alarm pane would display the condition with a time stamp
indicating an alleged, but incorrect, time that the autonomous notification was issued. Clicking the CTC
alarm “Synchronize” button at this stage will correct the alarm time stamp. There is no way to remedy
the lack of reference number. This issue will be resolved in Release 6.0.
DDTS # CSCea78364
Simultaneous failure of working and protect cards in 1:N protection groups may not be alarmed as
service affecting. This can occur when the working card of the protection group has been removed from
the chassis, and the protect card of the protection group is subsequently issued a Manual Reset. Since
the working and protect facilities are impaired, the Improper removal alarm should clear and be reissued
as a Critical and service affecting condition. This issue will be resolved in Release 6.0.
DDTS # CSCea61887
Terminal loopback is provisionable even if the card is in transponder mode.
To see this, in the provisioning tab for a G1000 or G1K-4 card pick a pair of ports and set them to
transpond with each other. The condition also holds true by picking one port and setting it to transpond
with itself (one-port unidirectional). Once the transponder setting is provisioned, go to the Maintenance
tab and attempt to provision terminal loopback on any of the ports that were previously provisioned for
transponder functionality. CTC allows terminal loopback to be provisioned even though the setting has
no effect due to the fact that the ports are performing transponder functions. If terminal loopback is truly
intended, you should remove the transponder settings. A warning stating that terminal loopback has no
effect if transponders are present will be displayed in Release 4.6.
DDTS # CSCeb20996
While using the orderwire capability of the AIC-I, you must not input a station number with less than 4
digits. If you enter, for example, 123, CTC will display 0123; however, you will not be able to ring the
node by dialing either *123, or *0123. This issue will be resolved in Release 4.6.
