553-3001-306 Standard 10.00 January 2002
DID calls which terminate on an Attendant Console result in either a
Multifrequency Compelled IDLE or IDCT signal being returned, depending
on the customer option. This applies to both direct and intercept calls.
When an Attendant Console is in Night Service, the signal being returned is
determined by the customer option and not by the classification of the night
DN, unless a DID call comes into a night DN.
When a DID call is diverted prior to termination, either by Call Forward,
Hunting, or Call Forward Busy, the signal being returned is determined by the
called party extension classification.
If a DID call terminates at a Multiple Appearance DN in which at least one
station has malicious call trace allowed Class of Service, then a
Multifrequency Compelled IDCT signal is returned to the Central Office. If
all stations sharing the DN have Malicious Call Trace denied Class of
Service, a Multifrequency Compelled IDLE signal is returned.

Recorded Announcement for Calls Diverted to External Trunks
DID calls to a busy Recorded Announcement (RAN) trunk group are queued

returned.
Trunk Supervision
Once a Multifrequency Compelled IDCT signal is returned, the disconnect
trunk supervision is limited to the called party.
