Page 1922 of 3156 Lockout, DID Second Degree Busy, and MFE Signaling Treatments
553-3001-306 Standard 10.00 January 2002
Direct Inward Dialing (DID) calls to a telephone set in Second Degree
Busy (i.e., a set that is busy on a call, and has another call waiting or
camped-on) state are either disconnected, receive busy tone, or routed to
the attendant. If the Second Degree Busy Disconnect (DSTD) option is
defined, the call treatment depends on the Class of Service of the second
degree busy telephone set; Forward Busy Allowed (FBA) causes the
calls to be call forwarded busy to the attendant, while Forward Busy
Denied (FBD) causes the calls to receive busy tone.
MFE signaling provides call status information for DID calls over MFE-
registered trunks. If a call tandems across an Integrated Services Digital
Network (ISDN) network, this enhancement allows the call status
information to be sent to the incoming MFE trunk from any outgoing
ISDN trunk.
