This feature provides the benefits and additional feature compatibility of Key-
Common Channel Interoffice Signaling (K-CCIS) between multiple systems including
NEAX PBX systems connected together over a Data Communication IP Network
(Intranet). Voice signals and common signaling data from/to the distant offices are
converted into IP Packets and transmitted through the Data IP Network. When using
the IP (K-CCIS) to NEAX (Point-to-Multipoint) feature, both voice and data
communication lines are integrated into one network and communication costs can be
reduced.
This feature is available between Electra Elite IPK II systems and NEAX PBX
systems. When connecting to a NEAX system, IPT cards are used and must be
installed.
