Pure IP switching provides communications between IP Dterms and also provides CCIS network connections with other NEAX 2000 IPS systems. TDM switching provides for communication between legacy stations and trunks. Connections between IP Dterms / CCIS-over-IP and legacy stations / trunks are made via IP Pads, which convert packet-based voice/data to TDM-based voice / data and vice versa.

The NEAX2000 IPS functions as a standalone telephony system supporting both IP and traditional circuit switched connectivity. Yet it can also be networked with other NEC telephony devices such as the NEAX IPS-DML, the NEAX2400 IPX and, of course, other NEAX2000 IPS units. In this case, the NEAX2000 IPS supports node-to-node peer-to-peer connectivity or node-to-node circuit switched connectivity. Each host can accommodate up to 255 nodes networked together.

The UNIVERGE NEAX2000 IPS supports a maximum of 952 IP stations, 512 TDM stations and a combined total of 980 stations. Up to 952 peer-to-peer IP stations and 64 legacy TDM stations are available in a single modular chassis. Up to eight chassis can be stacked together providing a maximum capacity of 512 TDM stations. Each host can accommodate up to 30 UNIVERGE NEAX IPS-DMR remote systems and up to 30 ISDN PRI links.

UNIVERGE NEAX 2000 IPS users have access to hundreds of service features that are used in building unique telephony applications that enhance productivity, reduce operating costs and improve communications efficiently.
