5.16.6 P25 CONVENTIONAL TELEPHONE
CALLS
General
Telephone calls can be placed and received on
P25 conventional channels if equipped with firmware
2.6 and 4.2 or later. This feature is not available with
1.xx (ARM) or 3.x (UCM) software versions. This
feature allows telephone calls to be placed and
received over the public telephone system using your
radio. Telephone calls are programmed to operate in
one of the following modes:
•
Disabled
•
Answer-only capability
•
List only - Telephone numbers can be selected
from a preprogrammed list only (direct entry as
follows is not allowed)
•
Unlimited - Telephone numbers can be selected
from a list and also dialed directly entered using
the front panel controls or the HHC keypad.
All models with the above firmware or later have
the capability to place telephone calls by recalling the
number from a list or dialing it using the front panel
controls or using the Handheld Control Unit (HHC)
telephone keypad. More information on how to do this
follows.
Access/De-Access Codes
P25 conventional telephone calls utilize an access
to access the system when placing a telephone call,
and a de-access code to terminate the call when it is
finished. These codes are preprogrammed in pairs by
the Access/De-Access Code list selected on the
conventional Per System screen, and up to 16 pair can
be programmed. Each conventional P25 channel can
be programmed to automatically select one of these
code pairs. They must match the system codes, and the
default code is *1P# (the P represents a pause).
