Instruction manual

Coverage callback
Issue 4 May 2003 211555-233-767
Coverage callback
Allows a covering user to leave a message for the called party to call back the
person who called.
Coverage incoming call identification
Allows multi-appearance telephones users without a display in a coverage answer
group to identify an incoming call to that group.
Disconnecting unanswered calls
Disconnects unanswered outgoing calls after a predetermined amount of time.
When any of the following timers expire during an outgoing local, toll, or
international call attempt, the switch disconnects the call and applies busy tone,
which may or may not be followed by howler tone:
■ Pre-dialing and interdigit timer
■ Outgoing seizure acknowledge timer
■ Answer supervision timer
■ 60-, 90-, and 120-second no-answer disconnect timers, based on ARS
call type
■ 120-second timer used for calls without a call type, such as calls to trunk
access codes
Distinctive ringing
Rings or activates alerting on your telephone in such a way that you are aware of
the type of incoming call before answering it. This feature operates in a
Distributed Communications System (DCS) environment the same as it does
within a single system.
By default, internal calls are identified by a 1-burst ringing pattern, external calls
by a 2-burst ringing pattern, and priority calls by a 3-burst ringing pattern. You
can administer these patterns, however.
