ISDN Call Logging

7-7

Troubleshooting

If both ports are busy, and Call Waiting has been disabled (i.e., S76), the third incoming call generates a busy signal to the far end.

If Call Waiting is enabled, and your telephone company has provisioned this feature on your ISDN line, you will hear the Call Waiting indicator (a click), alerting you to an incoming call. Refer to Chapter 6,“Supplementary Voice Features” for further ISDN Call Waiting assistance.

ISDN Call Logging

ISDN Call Logging displays the five latest incoming and outgoing numbers over the data and analog ports. To use this feature, your ISDN line must support Caller ID.

Conventional, or Analog Caller ID, which requires an additional external device to monitor incoming calls, is not supported by the 3C882 ISDN modem. However, you must have Caller ID enabled on your ISDN line to utilize the Call Logging feature.

To view the call log, use terminal emulation software to enter the command AT\N and then press Enter. If there had been any incoming or outgoing calls over the data (RS-232) port or analog ports, the telephone number of the caller (for incoming calls) or called party (for outgoing calls) is displayed followed by a time indicator. This time indicator shows the elapsed time between the specific incoming or outgoing call and the time you accessed the log to view the call information.

For example, if you enter AT\N and see an incoming call with a time of 7:30 logged, this indicates that call was received seven minutes and thirty seconds ago.
