Note:
If the duration period is set too long, the Lineside T1 card can be slow to return to service
automatically even when the carrier is no longer experiencing any errors. The Clear Alarm
command must be entered manually to restore service promptly. To avoid this, the duration
period should normally be set to 10 seconds.
Set Clearing
Use the Set Clearing (S C) command set to enable or disable alarm self-clearing. Answer Y
or N to the question: "Enable Self Clearing? (YES or NO)". If "Enable Self-Clearing" is chosen
(the factory default condition), the system automatically clears alarms after the alarm condition
is no longer detected for the corresponding duration period.
The "Disable Self-Clearing" option causes the system to continue the alarm condition until the
Clear Alarm (C A) command set is entered. Line processing and the yellow alarm indication to
the CPE is terminated as soon as the alarm condition clears, even if "Disable Self-Clearing" is
set.
Display Configuration
The Display Configuration (D C) command set displays the various configuration settings
established for the Lineside T1 card. Entering the Display Configuration (D C) command set
causes a screen similar to the following to appear:
