Digital Channel Information

Function: Set digital channel parameters.

Local number: The unique unit identier used to identify an individual

radio/ radio user.

Group call timer: Maintains group call for the period of the timer for

the group call users.

Private call timer: Maintains the private call for the period of the timer

so the two units in the call do not drop out of private call until timer

expires.

Transmit pre-carrier time: The transmitter carrier period before data

or control information is sent to insure information will be sent properly.

It is to insure that other receivers have been captured before data

is sent. It should be carefully set to support the needs of the system

since it does consume channel resources. For example, time may be

extended to insure scanning radios stop on channel.

Voice delay: This parameter denes the overall voice delay when the

transceiver initiates voice communication.

Time out timer (TOT): Ensures that a channel is not used for an

extended period that may consume resources and cause damage to

the radio.

Timeout: The maximum amount of time allowed for continuous

transmit. The radio will emit a local warning tone and will stop transmit

when programmed time is met.

Early warning time: A pre-alert tone may be set to tell the user that

the timeout time is about to be met. The alert will sound locally.
