5.13.6 P25 Conventional Telephone Calls
Telephone calls can be placed and received on P25 conventional channels. Telephone
calls to be placed and received over the public telephone system using your radio require a
Network Interface Unit (NIU). 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 keypad on the HHC.
All models 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.
5.13.6.1 Access / De-Access Codes
P25 conventional telephone calls use an access code 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, 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).
5.13.6.2 Placing a Telephone Call
To recall from list:
1 Select the conventional channel that is programmed to select the desired access and de-
access codes.
