Hybrid System of IP (peer-to-peer connection) and TDM Switching
The
U
NIVERGE NEAX
Division Switching (TDM). The pure IP switching is provided for communications between DtermIPs
and for CCIS/Remote PIM connections with another
DML/2400 IPX (CCIS over IP or Remote PIM over IP). On the other hand, the TDM switching is
provided for communications between legacy stations/trunks. Connections between DtermIP/CCIS or
Remote PIM over IP and legacy stations/trunks are made via IP PADs, which converts packet-based
voice data to TDM-based voice data, and vice versa.
Built-in DRS (Device Registration Server) on MP
The
U
NIVERGE NEAX
a Log-in/Log-out management of DtermIP including Registration, Authentication. Also the built-in DRS
can be inter-worked with DHCP server to provide easy administration of IP address
Reduced Hardware with IP based Architecture
The DtermIPs accommodated in a LAN do not require a DLC card because they can be interfaced
directly with the LAN and connected on a peer-to-peer basis. When a DtermIP is connected with
station/trunk, which is accommodated in TSW, the speech path between LAN and TSW is made via IP
PAD under the call processing control of MP. The number of DtermIPs can be simply expanded by
adding the terminal itself, an IP Seat License and IP PADs if traffic volume is increased. With this
system architecture, the hardware such as DLC, PIM, Power Supply etc. is reduced and easy cost
effective move, add, change is realized.

Various Installation Methods
To meet the specific needs of the customers' environment, the
following installation methods:
Floor Standing Installation
Wall-mounting Installation
IEC standard 19-inch Rack-mounting Installation
Unified Circuit Card Size
All the circuit cards for
the PIM. This maximizes the efficiency of slot utilization of the PIM.
High Density Line/Trunk Cards
Major line/trunk cards used in
allows the physical system size to be compact.
