Chapter 1 Introduction
NEAX 2000 Internet Protocol Server (IPS)
NEAX 2000 Internet Protocol Server (IPS) is a full-featured IP-based
communications system providing a rich feature set of existing NEAX 2000 IVS
2
,
with pure Voice over IP (VoIP) communications (Peer-to-Peer connections), across
corporate Local and Wide Area Networks (LAN and WAN).
Dterm 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 Dterm IP telephones with voice compression, offering existing Dterm Series
E telephone features. In a WAN, the system can provide Peer-to-Peer connections
over IP networks with voice compression through CCIS (CCIS over IP).
The NEAX 2000 IPS can 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 and ISDN). The Legacy
station/trunk interface cards (LT and AP cards) can be accommodated in the Port
Interface Module (PIM), in the same manner as the NEAX 2000 IVS
2
. At maximum
configuration, the NEAX 2000 IPS supports 512 LT ports which can be 448 Dterm IP
telephones and 64 Legacy LT ports, and 256 ports for Legacy AP cards.
Communications between Legacy stations/trunks and Dterm IP telephones/IP
networks are made via IP PAD, that converts packet-based voice data to TDM-based
voice data, and vice versa. The new Main Processor (MP) card controls both
Peer-to-Peer connections and TDM-based connections. The new MP card
incorporates a built-in Device Registration Server (DRS) and single interface point of
IP connections to IP telephone, MATWorX, and OAI/ACD servers.
