From a maintenance perspective, Option 11C DTI/PRI operation consists of
these major aspects:
• hardware and software states
• near-end and far-end status
• link and/or span integrity
• clocking status
• frame alignment
Option 11C PRI operation is monitored and reported on through maintenance
messages, out-of-service alarms, and circuit card faceplate LEDs. Bantam
monitor jacks are located on the faceplate of the NTAK09.
Option 11C maintenance provides several tools, either manual or automatic,
for maintaining effective PRI operation. These tools are service change and
maintenance commands that are accessible through the software overlays and
resident diagnostic routines.
The following sections describe the maintenance messages that may appear
on the Option 11C maintenance TTY as a result of DTI or PRI operation.
D-channel status and error conditions are reported as DCH messages. PRI
status and error conditions are shown in Table 8. (Additional information on
PRI and DCH messages can be found in the X11 System Messages Guide
(553-3001-411).
