Sessions

A DSC session (or automated procedure) 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 17.
