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.

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.

2 Momentarily press the PHONE option switch, make the menu selection, or press the 

PHONE soft button (Lightning Control Head only). The display indicates the last 
number dialed by alternately displaying “LAST NUM” and the telephone number. In 
addition, the phone mode is indicated by the 

 icon (Standard Control Head) and the 

 for the Lightning Control Head.

3 If required, rotate the Select switch to display the desired number. The alias and 

telephone number are alternately displayed.
