1.4 NETWORK APPLICATION
The equipment can be used in the following operating modalities:
Trunked Mode
The Peripheral-Peripheral and Peripheral-Fixed connections take place through
the Network (Air Interface Protocol).
Call Control manages the activation, maintenance and release of voice/data calls
and is capable of managing up to four calls simultaneously.
The calls can be Individual or Group.
Direct Mode
The Peripheral-Peripheral connection takes place directly. In this case the
Peripheral-Network connection is not possible unless supported by Gateway which
constitutes the connecting element.
Dual Watch Mode
The radio unit shall support Dual Watch Mode and than it is able of operating both
in Trunked and Direct mode although not simultaneously.
Dual Watch Mode enables the user to monitor the trunked mode control channel
while operating in Direct Mode and to monitor the channel in Direct Mode while
operating in Trunked Mode. This allows the user to switch from one operating
modality to another, but only when the radio is in IDLE status or when the call is
not active.
