1. The CNG signal is monitored over a 4-second silent period following reception of the incoming call. If
the CNG signal is detected, the Fax Reception mode is set. If the CNG signal is not detected, the TAM
OGM is played back to the caller. Subsequently the ICM recording mode is set.
If a busy tone is detected during ICM recording, the line is disconnected.
If a silent period is detected for 6 seconds, the Fax Reception mode is set.
Note that the Remote Control Code is monitored from the time the call is answered until the start of
ICM recording. When the Remote Control Code is detected the unit awaits for the input of command.
This procedure is illustrated in the diagram below.
