CHAPTER 2 SYSTEM CONFIGURATION
NEAX 2000 IPS General Description Page 33
NDA-24345, Issue 3
IPS System Conditions
2000 IPS is an IP communication system that integrates voice terminals through Peer-to-Peer
connection to the IP network. The system is a hybrid system to accommodate both IP multiline
terminals (DtermIP) and the Legacy PBX’s terminals (Legacy terminal). Line/Trunk cards and
Application Processor cards can be mounted in the system to provide the Legacy PBX features that
use the Time Division Switch (TDSW).
Station-To-Station Connection
Station-to-Station connection is available on the LAN. For DtermIP-to-DtermIP connection
(Peer-to-Peer connection), the voice data is transmitted and received directly between
DtermIPs on the LAN. For DtermIP-to-Legacy terminal connection, the IP-PAD card is
required to transmit and receive the voice data. This card is used to control and convert the
voice data. The MP card manages control signals in both types of connections.
Public Network/TIE Network Connection
The system can be connected with a Public Network or Tie Line Network. When the
DtermIP communicates with the DtermIP/Legacy terminal in the destination office via Public
Network or Tie Line Network, the IP-PAD card and the trunk card are required to transmit
and receive the voice data.
CCIS Connection
The system can be connected with the IP network by No. 7 Common Channel Inter-office
Signaling (CCIS) via the Virtual IPT, when the destination office is 2000 IPS or 2400 IPX.
For DtermIP-to-DtermIP connection via CCIS (Peer-to-Peer connection), the voice data is
transmitted and received directly between DtermIPs via the IP network (CCIS via IP). For
DtermIP-to-Legacy terminal connection via CCIS, the IP-PAD card is required to transmit
and receive the voice data. This card is used to control and convert the voice data. The MP
card has a built-in Virtual IPT and the Virtual IPT manages control signals in both types of
connections.
H.323 Connection
The system can be connected with the IP network by ITU-T recommendation H.323
protocol. The system can be connected to the terminal and network equipment according to
H.323 protocol. For DtermIP-to-DtermIP connection via the IP network with H.323
protocol, the IPT card and IP-PAD card are required to transmit and receive the control
signal and voice data. For voice compression, the 4VCT card is required. For Legacy
terminal connection via the IP network with H.323 protocol, the IPT card is required. For
voice compression, the 4VCT card is required.
