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.
Functional description
The NTCK16AX and NTCK16BX generic Central Office trunk cards support up to eight analog
Central Office trunks. They can be installed in any IPE slot.
Both cards are exactly the same except for the Periodic Pulse Metering (PPM) feature. The
NTCK16AX card supports internal 12/16 kHz PPM but the NTCK16BX card does not.
