1.4.6Clear Channel Alerting

If a call is attempted and no trunking channels are available, the subscriber will get a busy signal. The subscriber can try to redial over and over until the call is processed but this is very frustrating. Clear Channel Alerting Mode eliminates this problem.

If Clear Channel Alerting Mode is enabled and all channels are busy when a call is attempted, a busy signal will be generated by the ST-865M3. After the busy signal, the ra- dio will continue to scan all trunking channels looking for a free channel. The radio will chirp every 10 seconds while in this mode. When a channel is free, the radio will generate a double beep ( low then high). The subscriber can then at- tempt to place another call or use the Redial feature (press- ing * twice). The ST-865M3 will not automatically redial. If other subscribers are using the clear channel alerting mode at the same time, the first subscriber to attempt a call will capture the channel.

Once a clear channel is detected, the Clear Channel Alerting Mode is canceled.

The subscriber can cancel the Clear Channel Alerting Mode and return to the Trunking Mode by pressing any key on the radio front panel numberic keypad. Clear Channel Alert- ing is a dealer programmable option.

1.5Call Termination

A subscriber ends a call by pressing the pound key (#) on the radio front panel keypad. The ST-852M will disconnect and release the channel. For group calls, all of the subscribers in the group will be disconnected.

Call termination will also occur if the subscriber exceeds the call limit time, or if the subscriber unit activity timer expires at the ST-852M. See the ST- 852M SmarTrunk II Digital Trunking Controller manual for details about setting these times. In addition, if a subscriber unit loses the signal from the ST-852M for 5 seconds, the subscriber unit will return to the idle state.

A disconnect signal is indicated with a beep. After the beep, the sub- scriber unit returns to the idle state.
