5.13.8 P25 Conventional Telephone Calls
Telephone calls can be placed and received on P25 conventional channels with a Network
Interface Unit (NIU). EFJohnson also supports telephone calls to be placed and received
over other vendor’s public telephone. 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
(press and hold) entered using the front panel controls or the keypad on the Digital
Keypad Microphone.
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 keypad on the Digital Keypad
Microphone. More information on how to do this follows.
5.13.8.1 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 255 pairs 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).

To recall from list:
1 Select the conventional channel that is programmed to select the desired access and de-
access codes.
