CCIS Networking via IP (Non Peer-to-Peer Connections Basis)

IP trunk connections over CCIS (No.7 CCIS Common Channel Inter-Office Signaling) Networking via IP is used to provide telephony services between the 2000 IPS, IVS2, IPS Retro or 2400 IMX/IPX and Electra Elite IPK/IPKII on opposite side which do not support peer-to-peer connections. The IP-PAD is required for connections between IP terminals and IP trunks. A maximum of one IP trunk card can be accommodated per PIM with a maximum of eight IP trunk cards per system. Voice compression of G.729a (8 kbps) and G.723.1 (5.3 kbps / 6.3 kbps) can be provided by the IP trunks with VCT cards.

Communications cost can be reduced, by utilizing IP Trunks in the system to convert voice signals into IP packets and transmit them over the data network. All CCIS centralized and transparent features can be used connecting up to 255 NEAX systems in a network for a total of 130,560 station ports.

Point-to-Multipoint Connection

Point-to-Multipoint Connection is a connection type, which designates multiple destination IP addresses, per IP trunk, as shown below. One IP trunk can be connected to multiple opposite offices in Point-to-Multipoint connection.
