What is a DSC session
A DSC session is a collection of DSC calls (transmitted and/or received) that are
related to the same event (e.g. a distress event) or established call (e.g. an
individual call request followed by an acknowledgment).
A session can be either active or on hold. The active session has control over the
radio transmitter. A session can have a purpose. For example if the purpose is to
establish communication on a working channel.
The non-DSC VHF communication is considered as a session that can be active
(engaged) or on hold (dis-engaged). See also Engagement status on page 19.
Display for active DSC session
When a DSC session is active, the
display shows the type of session,
the current state, MMSI number
of the other party and elapsed
time since the reception of a call
request or an acknowledgment.
The session category text (in this example DISTRESS) is for the
active call. The session category icons show the category of the
other ongoing sessions
