PBX System Designation
PBX system is designated as “PBX” or “system” usually.
When we must draw a clear line between the PBX systems, they are designated as follows.
2000 IPS : NEAX 2000 IPS INTERNET PROTOCOL SERVER
IPSDMR : NEAX IPSDMR INTERNET PROTOCOL SERVERDMR
IPSDM : NEAX IPSDM INTERNET PROTOCOL SERVERDM
Terminal Name
The following IP terminals are designated as “DtermIP” usually, unless we need to mention the type of ter-
minal in particular.
DtermIP (IP Adapter Type) [For North America Only]
DtermIP (IP Bundled Type)
DtermIP INASET
DtermSP20
DtermSP30
NOTE 1: Dterm75 (Series E)/Dterm85 (Series i) terminal can be used as the IP terminal by attaching the
IP Adapter (IP Enabled Dterm). This terminal provides users with all features currently avail-
able in DtermIP.
NOTE 2: In regard to the China market, we have not released NEAX 2000 IPS INTERNET PROTOCOL
SERVER but NEAX 2000 is released.

SYSTEM OUTLINE
This system can be interfaced with an ISDN with the Primary Rate Interface or the Basic Rate Interface at
the reference point S/T and ISDN Terminal.
System Outline of ISDN-PRI
The system is configured with a 24/30-channel Digital Trunk Interface (DTI) for digital network interface,
D Channel Handler (DCH) for receiving/transmitting D channel signaling data from/to the ISDN ex-
change. Since the Main Processor (MP) contains Phase Locked Oscillator (PLO), the system can be syn-
chronized to the ISDN as a clock receiver office.
The figure below shows the system outline of ISDN-PRI.
