Overview
From a maintenance perspective, DTI/PRI operation consists of these major elements:
•
hardware and software states
• near-end and far-end status
• link and/or span integrity
• clocking status
• frame alignment
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.
System 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.
