Page 1946 of 3156 Make Set Busy
553-3001-306 Standard 10.00 January 2002
Digital Private Signaling System #1 (DPNSS1) Executive
Intrusion
Executive Intrusion is not allowed if either of these features is active at the
requested party.
Flexible Feature Code enhancement
The Deactivate FFC can be used to deactivate Make Set Busy.
Group Call
A Group Call to a telephone in Make Set Busy or Individual Do Not Disturb
mode cannot be completed. The telephone will not be rung and is not counted
as part of the Group Call (i.e., if all other members in the group have
answered, the lamp next to the Group Call key on the originator’s telephone
lights steadily).
Group Hunt
Make Set Busy (MSB) has priority over Group Hunting. Group Hunting will
skip over sets with MSB active.
Hot Line
Make Set Busy is overridden by the Hot Line feature. If a Meridian 1
proprietary telephone is in Make Set Busy mode, incoming Hot Line calls still
terminate (ring) on the telephone.
Idle Extension Notification
It is not possible to request Idle Extension Notification towards an extension
that has the Make Set Busy feature activated.
If Idle Extension Notification is requested for a Multiple Call Arrangement
DN, the first extension with this DN that becomes idle will cause the recall.
This extension will also be blocked from receiving calls.
ISDN QSIG/EuroISDN Call Completion
Sets that have Make Set Busy (MSB) activated can request Call Completion
to another DN, as the free notification overrides the MSB feature. Incoming
Call Completion to Busy Subscriber (CCBS) requests do not override the
MSB feature. A set is considered busy while MSB is active. A CCBS request
is registered against a busy set, but only advances when the MSB feature is
deactivated and the set remains free.
