Hardware Architecture

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 (TDM). The pure IP switching is provided for communications between DtermIPs and for

CCIS/Remote PIM connections with another NEAX 2000 IPS/ NEAX IPS

/2400 IPX (CCIS over

IP or Remote PIM over IP). On the other hand, the TDM switching is provided for communications

between legacy stations/trunks. Connections between DtermIP/CCIS or Remote PIM 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.

Powerful, One-board Main Processor (MP) with Integrated Functionality

The NEAX 2000 IPS Main Processor (MP) is the heart of pure IP connections and TDM-based

connections. The MP employs a high-speed CPU, which is equivalent with Pentium. With this

processing power and System On Chip (SOC) technology, the MP integrates Device Registration

Server (DRS), AP01 (OAI) functions, which are provided by an additional card in the previous IVS

series. Also, by means of today’s advanced LSI technology, the MP card size is minimized and On-

board Ethernet Interface card is mounted on the MP without using an additional slot space in the

PIM. This interface card is linked with LAN for call control processing of DtermIP and inter-work

with MATWorX and OAI server.

The MP provides LAN control function, System-based Device Registration Server (DRS), Built-in

FP, Built-in OAI, Built-in SMDR, Built-in CCH-IPT, 33 MHz PCI BUS, Memory

(Basic/Expansion), TDSW (1024 CH × 1024 CH), 16-line CFT, PB Sender, Clock, PLO two ports

(Receiver Mode/Source Mode), two RS-232C Ports, two-line DAT (Recording duration: a maximum

of 128 seconds), DK, 4-line PB Receiver, Modem for remote maintenance (33.6 kbps), internal

Music-on-Hold Tone, BUS Interface. BUS Interface functions as a driver/receiver of various signals,

adjusts gate delay timing and cable delay timing, monitors I/O Bus and PCM BUS. One card is

required per system.

Reduced Hardware with IP based Architecture

The DtermIPs connected to the LAN do not require DLC cards because they can be interfaced

directly with the LAN and connected with peer-to-peer basis. When the DtermIP is connected to a

station/trunk that is using TSW, the speech path between LAN and TSW is made via IP PAD under

the call processing control of the MP. The DtermIP can be expanded simply adding the terminal

itself and IP PAD if traffic volume is increased. With this system architecture, the hardware such as

DLC, PIM, Power Supply etc. is reduced and easy moves, adds, and changes can be realized.
