Observe the LED on the card as it performs self-tests. The
LED should blink three times and then stay on until enabled by
software. When enabled by software, the LED turns off if card
is operational.
Install line cards in slots 1 through 8.
a Install the local MMI terminal and T1 carrier link cables to
the RMI Multi-I/O Cable Assembly (NT5D87). See
"Remote Mini-carrier Interface cabling" (page
b Pull the card locking devices away from the faceplate and
insert the card into the card guides of a line card slot.
c Slide the card into the module until it engages the backplane
connector and then push the locking device levers toward
the faceplate to insert the card connector into the backplane
connector and lock the card in place.
Repeat step 6 for each line card.
Refer to the following when installing the NT7R87BA T1 CSU
cable kit to connect the T1 carriers from the LMI and RMI to the
CSU:
•
Connect the NT7R93BA adapter to P2 (carrier 0) or P3
(carrier 1) of the LMI or RMI I/O cable.
•
Connect the 32' span cable to the NT7R93BA adapter.
•
If your CSU terminates to an RJ45 connector, directly
connect the other end of the span cable to the CSU.
•
If your CSU terminates to a DB15 connector, connect the
NT7R93AA adapter to the CSU and connect the span cable
to the adapter.
For proper operation of the Mini-Carrier equipment, the following
should be verified:
•
line build-out switches are set to accommodate a cable length
that corresponds to the approximate length to the CSU
•
CSU is configured for the same framing format as the MCR
(D4 or ESF)
•
CSU is not configured for robbed-bit signaling
•
CSU accepts B8ZS zero substitution codes
Unused carrier links should be configured as "unequipped"
(using the set configuration command from the Man Machine
Interface terminal), to avoid a constant alarm condition. The
alarm relay contacts will remain active during such an alarm
condition.
