What is a Session?
A DSC session is defined as 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
acknowledgement).
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 a 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 18.
