NEAX 2000 IPS General Description Page 14
NDA-24345, Issue 3
Station to Station Connection
For DtermIP to DtermIP connection (Peer to Peer connection), the voice data is transmitted and
received directly between DtermIPs on the LAN. For Dterm Legacy terminal connection, the IP-
PAD card and VCT card are required to transmit and receive the voice data. These cards are used to
control and convert the voice data. The MP card in either of the connections above manages the
control signals.
CCIS Connection
DtermIP to DtermIP connection (Peer to Peer connection) via CCIS is available only when the
destination office is NEAX 2000 IPS or NEAX 2400 IPX. The system provides only Point to
Multipoint connection.
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).
Dual MP System
The system complies with dual control system on Main Processor.
Note: Since the system employs Cold Standby processing in MP changeover, the calls in progress
are terminated as a result of the MP changeover. Also, during the MP changeover, the call
originating/receiving and service feature access are not effective. (It takes about 30 to 60 seconds to
complete the MP changeover.)
Remote PIM over IP with Survivability
The NEAX 2000 IPS can have a PIM installed at a remote site through an IP network. At the main
site, the NEAX 2000 IPS/NEAX IPS
DM
is installed and NEAX 2000 IPS/NEAX IPS
DM
/ NEAX
IPS
DMR
are installed at the remote site. The main site controls call processing and service feature
access for station users located at both the main and remote sites. When the Remote PIM cannot be
connected with main site due to the IP network and/or main PBX failure, the Remote PIM initializes
the system and re-starts operation by its own Main Processor (survival mode). In the survival mode,
almost all service features are provided to the station users accommodated in Remote PIM. When
the IP network/main PBX recovers, the Remote PIM can be restored to normal mode with a system
initialization by manual operation or automatically (Selectable by system data setting).
