Enhanced Built-in Firmware Processor (FP) on MP
The Firmware Processor card (FP) provides Line/Trunk interface, Memory (RAM 768 KB), and
inter-module BUS interface. BUS interface functions as a driver/receiver of various signals,
adjusts gate delay timing and cable delay timing, and monitors I/O Bus and PCM BUS. When
the system consists of three PIMs or more, one each of this card is mounted respectively in PIM
2, PIM 4, and PIM 6.
Extended Application Processor (AP) Port Capacity
The UNIVERGE
NEAX
1020 ports for the Line/Trunk (LT), therefore, more AP cards such as T1/E1 digital link cards
can be used in the system.
Universal Slot
One PIM provides 12 card slots for Line/Trunk (LT). Also, these card slots can be used for
Application Processor (AP) cards without complicated limitation. This makes easy quotation
and installation, and more AP cards can be mounted in one PIM.
Unified Circuit Card Size
All circuit cards for the UNIVERGE
installed in the PIM. This maximizes the efficiency of slot utilization of the PIM.
High Density Line/Trunk Cards
The major line/trunk cards used in the UNIVERGE
per card. This allows the physical system size to be compact.
DC/DC Power Supply for –48V
The PIM houses optional DC/DC Power Supply for the cards which require –48V power such as
the CSI card used for interface of Zone Transceiver of wireless system. Since this power supply
is mounted in the space under the AC/DC power, no additional Power Module/card slots are
required.
Built-in DRS (Device Registration Server) on MP
The UNIVERGE
NEAX
DRS provide Log-in/Log-out management of DtermIP including Registration and
Authentication. Also, the built-in DRS can be inter-worked with DHCP server to provide easy
administration on IP address.
Office Data Backup Enhancement
The office data of the UNIVERGE
period is extended compared with previous IVS series which were using RAM with battery.
Various Installation Methods
To meet the specific needs of the customer's environment, the UNIVERGE
provides the following installation methods:
Floor Standing Installation
Wall-mounting Installation
IEC standard 19 inch Rack-mounting Installation
