Chapter 12 — NTMW44 Universal Trunk Card
When the card is installed, the red Light Emitting Diode (LED) on the
faceplate flashes as the self-test runs. If the self-test completes successfully,
the card is automatically enabled (if it is configured in software) and the LED
extinguishes. If the self-test fails, the LED remains lit. The LED will also
remain lit if one or more units on the card become disabled after the card is
operating.
Each unit on the card connects to the backplane through an edge connector.
The faceplate of the card is equipped with a 50-pin Amphenol-type connector
for cabling to the cross-connect terminal.
At the cross-connect terminal, each trunk unit connects to external apparatus,
such as Central Office facilities or Recorded Announcement equipment.
The NTMW44 can be installed in any slot in the main cabinet or the
NTMW08 expansion cabinet.
