7.10.4 Subscriber Unit-Originated Special Calls
Telephone - These are calls to or from a subscriber unit made through the Public Switched
Telephone Network (PSTN).
Unit/Directed Group - These calls allow a subscriber unit to communicate with any
individual subscriber unit or group at the same site or another Multi-Net site (when several
Multi-Net systems form a network). Calls to specific radios are called Unit (Unit) calls,
and calls to specific groups are called Directed Group calls.
Directed Group calls allow communication with groups that are otherwise not accessible
because no selectable system has been programmed with the home repeater or group ID of
those radios. Directed Group calls can be made to any home repeater on any group ID
code from 1-225.
7.10.5 Radio Programming For Special Calls
Telephone and Unit calls are each programmed on Multi-Net systems for one of the
following modes:
• Disabled
• Response Only
• Send and Receive
To originate and answer a telephone call, the Phone option button or menu parameter must
also be programmed. Likewise, to originate Auxiliary calls (Unit/Directed Group), the
Unit option button or menu parameter must be programmed. The Unit option button/menu
parameter is also required to answer Unit calls.
A special channel does not need to be selected to place and receive Telephone and Unit
calls. All that is required is that the selected channel must be linked to a system that has the
desired call authorized as just described and have the correct unit ID.
