Physical description

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.

Self Test

The faceplate of the NT1R20 OPS analog line card is equipped with a red LED. 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. See
faceplate on page 119.
