Tie trunks terminate on the attendant console, at station sets, in hunt groups, or on night bells. They may also be arranged as dial-in tie trunks or tandem trunks. Like CO trunks, tie trunks are arranged in groups. Dial-in tie trunks are assigned a Class of Service in the same manner as stations, and they can be given access to selected features.
Tie trunks are subject to Interconnect Restrictions.
Incoming tie trunks override Do Not Disturb and cannot be forwarded from the station.
