Physical description
The line interface and common multiplexing circuitry is mounted on a 31.75
cm by 25.40 cm (12.5 in. by 10 in.) printed circuit board.
The OPS analog line card connects to the IPE backplane through a 160-pin
connector shroud. A 25-pair amphenol connector below the card is cabled to
the cross connect terminal (also called the Main Distribution Frame (MDF)).
Telephone lines from station equipment cross connect to the OPS analog
line card at the cross connect using a wiring plan similar to trunk cards.
The OPS card measures 31.75 by 25.40 cm (12.5 by 10 in.) It connects to
the IPE backplane through a 160-pin connector shroud. A 25-pair amphenol
connector below the card is cabled to the cross connect terminal. Telephone
lines from station equipment cross connect to the OPS analog line card
at the cross connect using a wiring plan similar to trunk cards. (See
Communication Server 1000M and Meridian 1 Large System Installation
and Configuration (NN43021-310) for cross connect terminations).
The NT1R20 Analog Line Card measures 31.75 cm by 25.40 cm (12.5 by
10 in.). It connects to the backplane through a 160-pin connector shroud. A
25-pair amphenol connector below the card is cabled to the cross-connect
terminal. Telephone lines from station equipment cross-connect to the
NT1R20 OPS Analog Line Card at the cross-connect using a wiring plan
similar to trunk cards.
The OPS analog line card mounts in any IPE slot. The line interface and
common multiplexing circuitry is mounted on a 31.75 cm by 25.40 cm (12.5
in. by 10 in.) printed circuit board.
The OPS analog line card connects to the IPE backplane through a 160-pin
connector shroud. The backplane is cabled to the input/output (I/O) panel
on the rear of the module, which is then connected to the Main Distribution
Frame (MDF) by 25-pair cables. Telephone lines from station equipment
cross connect to the OPS analog line card at the MDF using a wiring plan
similar to that of trunk cards. See Communication Server 1000M and
Meridian 1 Large System Installation and Configuration (NN43021-310) for
termination and cross-connect information.
The faceplate of the card is equipped with a red LED. See Figure 21 "OPS
analog line card - faceplate" (page 123) . When an OPS analog line card
is installed, the LED remains lit for two to five seconds while the self-test
runs. If the self-test is completed successfully, the LED flashes three times
and remains lit. When the card is configured and enabled in software;
then the LED goes out. If the LED continues to flash or remains weakly
lit, replace the card.
