Handling multiple calls — DSC and voice
The SAILOR 6300 MF/HF DSC can control multiple DSC sessions
simultaneously with a voice communication session. All sessions can keep
track of their session state and the communication channel used. They are
handled in their respective sessions, in the order as they are started up.
A call — or session — can be on hold (
HOLD
) or
active (
ACTIVE
). If there are several calls
ongoing, they are shown as tabs in the display
with their state (active, on hold, requiring
attention). The DSC sessions on hold can
receive calls that are pertinent to the session,
even when the session is not displayed.
To close a session, the session must be active, then press the soft key
QUIT
.
In case there are simultaneous alarms, they are sorted according to their
priorities, the most important ones are shown first. In some cases alarm or
pop-up messages terminate automatically, then the display messages and
audible alarms also disappear automatically.
Geographical area calls
When making a DSC area call, you must
enter the position of the ship (x,y) and the
radius of interest r. This information is
transformed to a square with a corner
point (a,b) and the length of its sides,
a
and
b. Then the DSC message is
transmitted. The illustration on this page
shows the relation between the user
input — the white circle — and the
information transmitted —the grey
Note
Note that there is one active call or session at a time. Use the soft
key
to switch between the ongoing calls/sessions.
