Operation
soon the current DSC session is terminated. The call with the highest priority
(importance for safety or life) is shown first.
Handling a background session
The equipment is designed with the possibility to control a DSC session
simultaneously with a VHF communication session. The sessions can keep
track of their session state and the communication channel used.
If a DSC session is put on HOLD it is automatically put in the background (VHF
communication display appears on the previous communication channel).
The soft key
is used to toggle between the VHF communication and a DSC
session on hold.
The DSC session on hold can receive calls that are pertinent to the session,
even when the session is not displayed. If the background receives updates
the icon
is shown.
Example:
An individual call request has been
sent. While waiting for the
acknowledgement of the call,
communication is engaged on VHF
(press the soft key
HOLD
on the DSC
session view). The
acknowledgement is received from
the called station (the icon
is
shown). Press the soft key
and
ACTIVE
to engage in the DSC
initiated communication.
