132 Glossary
The traffic channel is the channel on a
trunking system to which the parties
participating in a call are directed to for
the duration of the call. When the call
ends, the traffic channel is returned to
the pool of channels for use in a new
call.
In trunking operation, the trunking
system manages the communications
channels used by the radio, and shares
a number of channels among a large
number of radio users.
A valid signal is a signal that the radio
responds to by unmuting the receiver.
A signal may be valid, for example,
when it is stronger than a minimum level
or has special signaling that matches
the signaling programmed for the
receiving radio.
