Digital Channel Information
Function: Set digital channel parameters.
Local number:
The unique unit identifier 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 defines 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.
