Issue 5
The UNIVERGE
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, ISDN etc.). At maximum configuration, the
system can provide 1020 ports for IP and legacy devices, and 256 ports for Application cards.
Communications between legacy stations/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 the Main Processor
(MP) card. The MP card incorporates a built-in Device Registration Server (DRS) and a single
interface point of IP connection to IP telephone, MATWorX, and OAI/ACD servers.
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. The innovative modular hardware and software design
allows efficient, effective growth within each module from its minimum to its maximum
configuration. The UNIVERGE
NEAX
2000 IPS software design is as advanced as its hardware. It
ensures the system will support evolving applications and have the reliability needed to compete
in today's world and into tomorrow's. The software is designed with modularity in mind.
Together, these modular building blocks allow customers to initially buy what they need and add
capacity and capabilities as the business demands, resulting in a greater degree of cost control for
new installations and for upgrades to features, capacities and the software versions.
