Radio Access Number
(
RAN
)
RAN is a signaling system designed for digital radio
communications.
When a channel is set up with a RAN, squelch will only
open when a call containing a matching RAN is received.
If a call containing a di
ff
erent RAN is made on the same
channel you are using, you will not hear the call. This allows
you to ignore (not hear) calls from other parties who are
using the same channel.
