type) telephone Administration program LD 10.
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.
