SYSTEM CONFIGURATION

Circuit Cards

The circuit cards used for NEAX 2000 IPS are divided into the following three types. According to these card types, the mounting location of card and port allocation of the Time Division Switch are varied.

Common Control Cards

-Main Processor (MP)

-Firmware Processor (FP)

Line/Trunk (LT) Cards

-IP PAD, Line Circuit (LC), Central Office Trunk (COT), Tie Line Trunk (LDT/ODT), etc.

Application Processor (AP) Cards

-SMDR/PMS/CIS/Hotel Printer Interface (AP00)

-T1/E1 Digital Trunk Interface (DTI)

System Conditions

Conditions for Peer-to-Peer Connection

For the communication between Dterm IPs, the voice data is transmitted and received directly, without converting voice packets into PCM and voice compression in the system.

Conditions for CCIS Connection

Dterm IP to Dterm IP connection (Peer-to-Peer connection) via CCIS is available only when the destination office uses NEAX 2000 IPS or NEAX 2400 IPX.

The built-in CCH-IPT of MP card can be connected to max. 127 trunks. The system provides only Point-to-Multipoint connection.

Conditions for H.323 Connection

When connecting to the IP network with H.323 protocol, the IPT card is required.

When connecting to the IP network with H.323 protocol, the voice data is transmitted and received via the IP-PAD card.

Conditions for Legacy Interface (LT/AP)

All Application Processor cards used in NEAX 7400 ICS M100MX* except AP01 and CC01 cards are available for the system.

All Line/Trunk cards used in NEAX 7400 ICS M100MX* are available for the system.

*“NEAX 7400 ICS M100MX” is marketed in North/Latin America and Australia as “NEAX 2000 IVS2” and in UK as “NEAX 2000 INTEGRATED VOICE SERVER.”
