RTU-292 Operations Manual

If the number is busy, the busy tones will be broadcast for approximately 5 seconds before the RTU-292 terminates the call attempt.

Once the RTU-292 detects ringback, the RTU-292 begins a 30 second timer and waits for the call to be answered. If this does not happen before the timer expires, the call attempt is terminated.

7.5.6After the Call Begins

The RTU-292 now enters its "Command Mode", meaning that the phone user may enter any of the available DTMF commands from Table 3-1. The Inactivity Timer will now begin to run. If this time expires (due to a lack of speech or other audio activity), the RTU-292 will give a series of 3 short beeps as a warning. The radio caller or the phone user may initiate activity within 5 seconds of the warning beeps to reset the timer. If neither user does so, the unit will then terminate the call.

To terminate the call at any time, the radio user may enter * # at any time. The phone user may also enter * # to hang up.
