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 UNIVERGE NEAX 2000 IPS or UNIVERGE NEAX 2400 IPX. The system provides only Point to Multipoint connection.

Maintenance

MATWorX IPS is used as the maintenance program for the UNIVERGE NEAX 2000 IPS. Direct connection (RS-232C), Modem connection and LAN (TCP/IP) connections are available to connect to the MAT (Maintenance Administration Terminal).
