Physical description

The NTCK16AX and NTCK16BX generic Central Office trunk cards uses
eight units. Each unit connects to the shelf backplane through an 80-pin
connector. The backplane is cabled to the I/O panel which is then cabled
to the cross-connect terminal. At the cross-connect terminal, each unit
connects to external apparatus by Tip and Ring leads.

Switch settings

There are no option switches on the NTCK16AX and NTCK16BX generic
Central Office trunk cards. All settings are configured in software.

Self-test

When the NTCK16AX and NTCK16BX trunk cards are installed and power
is applied to them, a self-test is performed on each card. The red LED on
the faceplate flashes three times, then remains continuously lit until the card
is enabled in software. If the self-test fails, the LED remains lit.
