OUTLINE OF EVENT BASED CCIS
Event Based CCIS allows a PBX customer who does not have tie lines to use the various Common Channel Interoffice Signaling (CCIS) feature by using ISDN lines as CCIS virtual tie lines. For the PBX customer who usually has low traffic, Event Based CCIS is available between NEC NEAX PBXs.
