Nortel Networks Circuit Card 311 - Manual (Page 575)

Physical description 575
In Meridian 1 Option 11C systems the NT8D14 Universal Trunk Card is
installed in slots 1 through 10 of the Main cabinet, or in slots 11 through 50
in the Expansion cabinets.
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
goes out. If the self-test fails, the LED lights steadily and remains lit. The
LED also turns on and remains lit if one or more units on the card becomes
disabled after the card is operating.
Each unit on the card connects to the backplane through an 80-pin
connector, the backplane is cabled to the Input/Output (I/O) panel, and the
I/O panel is cabled to the cross-connect terminal.
At the cross-connect terminal, each unit connects to external apparatus,
such as Central Office facilities or recorded announcement equipment.
Each unit connects to external apparatus by tip and ring leads which carry
voice, ringing, tone signaling, and battery.
