5.13.9 P25 Conventional Telephone Calls
Telephone calls can be placed and received on P25 conventional channels. For P25
Trunked/Conventional/Smartnet/SmartZone/Multi-Net Telephone Calls, the Land Mobile
Radio System must be connected to a telephone system. Users should check with the
System Administrator to see if Telephone Calls are allowed on their system. 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 pre programmed list only (direct
entry using the keypad is not allowed)
Unlimited - Telephone numbers can be selected from a list and also dialed directly using
the keypad.
DTMF keypad models can place telephone calls by recalling the telephone number from a
pre programmed list as just described. However, only DTMF keypad models can directly
dial telephone numbers using the keypad.
5.13.9.1 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 pre programmed in pairs, 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).
