This chapter provides an overview of the maintenance tools available for 2.0
Mb PRI or ISL features:
• commands used to maintain PRI, DDCH, DCHI and clock controller
hardware
• tests for 2.0 Mb PRI operation
• error detection for 2.0 Mb PRI, including the various thresholds found in
the 2.0 Mb PRI loop timers in LD 73.
To enable an NTAK79 or NTBK50 PRI circuit pack, follow one of the
appropriate procedures which follow.
1 Software enable all 2.0 Mb PRI cards using LD 60 (command ENLL N).
The DCHI will enable automatically from the enable PRI command.
2 Software enable the clock controller using LD 60 (command ENL CC 0).

command: TRCK PCK.
Within about 30 seconds the D-channel layer 3 should be established.
4 You can request the current status of the D-channel by issuing the
command STAT DCH. The system should respond DCH N EST in
LD 96 (meaning that the D-channel is established and operational).
