Maintenance
MATWorX IPS is used as the maintenance program for the NEAX 2000 IPS. Direct connection (RS-
232C), Modem connection and LAN (TCP/IP) connections are available to connect to the MAT
(Maintenance Administration Terminal).
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 D
term
IPs and for
CCIS/Remote PIM connections with another NEAX 2000 IPS/ NEAX IPS
DM
/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 D
term
IP/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.
Built-in DRS (Device Registration Server) on MP
The NEAX 2000 IPS incorporates DRS (Device Registration Server) on MP, which provides a Log-
in/Log-out management of D
term
IP including Registration, Authentication. Also the built-in DRS can be
inter-worked with DHCP server to provide easy administration of IP address
.
Reduced Hardware with IP based Architecture
The D
term
IPs accommodated in a LAN do not require DLC card because they can be interfaced directly
with the LAN and connected with peer-to-peer basis. When D
term
IP is connected with station/trunk,
which is accommodated in TSW, the speech path between LAN and TSW is made via IP PAD under
the call processing control of MP. The number of D
term
IPs can be simply expanded by adding the
terminal itself and IP PADs if traffic volume is increased. With this system architecture, the hardware
such as DLC, PIM, Power Supply etc. is reduced and easy cost effective move, add, change is
realized.
Office Data Backup Enhancement
The office data of NEAX 2000 IPS is stored in Flash ROM.
