10.12 DIGITAL VOICE OPERATION

Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and

private (encrypted). The voice modes are programmed on a per-group basis within each trunked system

and on a per-channel basis within each conventional system.

10.12.1 Clear Mode

The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice

signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be

monitored easily by unauthorized persons.

Groups or channels programmed for clear operation cannot transmit or receive digital or

private messages.

10.12.2 Digital Mode

The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide

improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and

channels programmed for digital operation transmit only digital signals. Message trunked group calls and

individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the

call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the

digital mode is disabled or inoperative.

1. If receiving an analog message trunked call, the radio responds in the analog mode during the hang

time on the working channel.

2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time.

3. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is

transmitted in the mode defined by the system mode as programmed for the current system if the ID

being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined

by the I-Call mode programmed in the list for that ID.

The overdial DTMF tones are not available while in the Digital Mode.
