SMARTNET / SmartZone / P25 Trunked Features
6.4 Private (Unit-To-Unit) Calls
Private calls allow calls to be placed to a specific radio unit. Either the Enhanced Private
Conversation™ or standard Private Conversation modes may be programmed depending
on the capabilities of the radio system. One difference between these call types is that the
Enhanced type provides an indication that the called mobile is not on the air and the
standard version does not. Operation in each of these modes is described in the following
information.
Note
With P25 Trunked operation, these calls are called Unit Calls, and they function the same
as the Enhanced Private Conversation mode described in the following information.
The Private Call option switch is required to place these calls, and either that switch or the
Call Response switch is required to receive them. Private calls are programmed to operate
in one of the following modes:
• Disabled
• Answer-only capability
• List only - Unit IDs can be selected from a preprogrammed list only (direct entry as
follows is not allowed)
• Unlimited - Unit IDs can be selected from a list and also dialed directly using the front
panel controls or the keypad on the HHC.
