NEAX 2000 IPS
Highlights
NEAX 2000 IPS highlights are as follows:
• Hybrid System of IP (Peer-to-Peer connection) and TDM Switching
The NEAX 2000 IPS supports both pure IP switching (Peer-to-Peer connections)
and Time Division switching. The pure IP switching is provided for
communications between Dterm IP telephones and for CCIS network with
another NEAX 2000 IPS/2400 IPX (CCIS over IP). On the other hand, the TDM
switching is provided for communications between Legacy stations/trunks.
Connections between Dterm IP/CCIS over IP and Legacy stations/trunks are
made via IP PADs, which converts packet-based voice data to TDM-based voice
data, and vice versa.

Note 1: CCIS over IP using Peer-to-Peer connections is available with the NEAX
2000 IPS and NEAX 2400 IPX only.
