INTRODUCTION

DtermIP 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 DtermIP telephones with voice compression, on a CCIS basis (CCIS over IP).

PHS cell station can also be connected to LAN with 100 Base T Ethernet as IP-BS.

IPS also provide Windows PC based softphone (Dterm Softphone SP30) to connect to LAN network and it provides IP enabled Dterm 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 (LT and AP cards) can be accommodated in the Port Interface Modules (PIM), in the same manner as the NEAX 7400 ICS M100MX*. At maximum configuration, total system capacity is 768 ports. The system can provide 512 ports for DtermIP telephones and legacy LT cards, and 256 ports for legacy AP cards. Communications between legacy station/trunks and DtermIP 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.

All Application Processor cards used in NEAX 7400 ICS M100MX* except AP01 and CC01 cards are available for the IPS system. All Business/Hotel/Data/CCIS/ISDN/WCS features are available. The following service features are now included on the MP card and do not require the AP01 card.

Authorization Code with AP01 Forced Account Code with AP01

Direct Inward System Access (DISA) with AP01 (For North America)/Remote Access to System with AP01 (For other than North America)

Call Forwarding set by DISA with AP01

*“NEAX 7400 ICS M100MX” is marketed in North/Latin America and Australia as “NEAX 2000 IVS2” and in UK as “NEAX 2000 INTEGRATED VOICE SERVER.”
