 NT5D11 and NT5D14 Lineside T1 Interface cards

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.

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
