Procedure 25
Inserting the NTRB21 TMDI card
Step Action
1 Check for available card slots in the base cabinet and print the
configuration record to determine which slots can be used. To do
this, enter the following command in LD 22:
PRT CFN in LD 22
2 If in PRI mode, enter the following command in LD 96 to software
disable the D-channel:
DIS DCH x
where x is the DCH port number that was assigned in LD 17.
3 If the Clock Controller is enabled, enter the following command in LD
60 to software disable it:
DIS CC 0
4 Hold the NTRB21 by the lock latch, unlock the latch, and slide the
card into the cabinet.
Note: Refer to Table 74 "Shelf slot assignments for NTRB21,
NTAK09, and NTAK20" (page 202) to determine the correct slot
in which to insert the card.
5 Enter the following command in LD 96 to enable the TMDI card:
ENL TMDI x ALL
where x is the NTRB21 TMDI card number (DLOP). The card
number associated with an NTRB21 TMDI card is based on the
slot in which the card is installed.
6 Within about 30 seconds, the D-channel layer 3 should be
established. To confirm, enter the following command in LD 96 to
request the current status of the D-channel:
STAT DCH (N)
The system response is:
