the card is in the normal mode of operation.
The LED is ON if:
„
the channel capacity of the card is zero.
or

the card is in maintenance mode.
Reset switch
The reset switch on the faceplate permits you to manually reset the card
without having to power down. You typically use this switch to clear a fault
condition during setup or during non-traffic periods.
ATTENTION!
Before using the Reset Switch you must ensure that the Nortel Call
Recording Card is disabled in LD32 using the DISC command. Otherwise
some of the ports may cause an OVD error on the Meridian CPU and
become disabled when the card resets. Once the card is reactivated (the
HEX display has passed the T:21 state) re-enable the card in LD32 using the
ENLC command.
Debug terminal access
Access the Nortel Call Recording Card debug terminal using an RS-232
port. You can access this port is using the NTAG81CA faceplate serial cable.
Messages indicating the completion of each self-test phase, as well as any
detected faults, log to this serial port.
The pinouts for the Mini-DIN Connector, to which the faceplate
maintenance cable connects, are shown in Table 14: “Faceplate connector
mini-DIN Connector pin-out,” on page 58.
The terminal connected to the serial port requires these settings: 9600bps, 8
data bits, 1 stop bit, no parity, and no flow control.
