INTRODUCTION
D
term
IP telephones are designed to provide a converged infrastructure at the desktop, with a 100 BASE-T
Ethernet connection to the LAN and built-in hub for a PC connection to the telephone itself. The system can
provide peer-to-peer connections between D
term
IP telephones with voice compression, on a CCIS basis (CCIS
over IP).
IPS also provide Windows PC based softphone (D
term
SP30) to connect to LAN network and it
provides IP enabled D
term
features without the telephone set.
Figure 1-2 NEAX 2000 IPS System Overview
The NEAX 2000 IPS can also provide legacy station/trunk interfaces to support the existing Time Division
Multiplexing (TDM) based infrastructure, such as analog telephones, analog networks, and digital networks
(T1/E1, ISDN etc.). The legacy station/trunk interface cards can be accommodated in the Port Interface
Modules (PIM). At maximum configuration, total system capacity is approx. 1,000 ports. The system can
provide 956 ports for D
term
IP telephones, 512 ports for legacy LT cards and 256 ports for legacy AP cards.
Communications between legacy station/trunks and D
term
IP telephones/IP networks are made via IP PAD,
which converts packet-based voice data to TDM-based voice data, and vice versa. Both peer-to-peer
connections and TDM-based connections are controlled by a new Main Processor (MP) card. The new MP
card incorporates a built-in Device Registration Server (DRS) and a single interface point of IP connections to
IP telephone, MATWorX, and OAI/ACD servers.
