General Information - NEC Univerge SV8100 System Configuration Manual

1. General Information

The SV8100 is a full-featured IP based communications system providing a rich feature set of
existing system, with pure Voice over IP (VoIP) communications, across corporate Local and Wide
Area Networks (LAN and WAN).
DT700 series telephones are designed to provide a converged infrastructure at the desktop, with a
10/100BASE-TX connection to the LAN and built-in hub for a PC connection to the telephone itself.
The SV8100 can provide peer-to-peer connections between DT700 series telephones with voice
term
compression, offering existing D IP telephone features with enhanced user interface. On the
WAN side, the system can provide peer-to-peer connections over IP networks with the voice
compression, on a CCIS basis (CCIS over IP).
Besides, the SV8100 can provide legacy line / trunk interfaces to support the existing Time
Division Multiplexing (TDM) based infrastructure, such as analog telephones, digital telephones
(DT300 series), analog networks and digital networks.
The new compact 19" KSU provides 104 (u-law) /111 (A-law) timeslots (80 digital terminals) and
can be expanded, using three additional 19" KSU, for a maximum of 416 (u-law) /444 (A-law)
timeslots (368 digital terminals). Through IP connection and four additional 19" KSU, the system
can be expanded to a maximum of 512 ports.
Also small compact 9.5" 3 Slot KSU (CHS2U GW-xx and CHS2U B-xx) provides 48 total ports (32
digital terminals) and supports any combination of existing stations and trunks between this
number. 9.5" KSU requires over version 2.0 software. CHS2U GW-xx does not have expandability
to use Expansion chassis. When PZ-BS10 is installed to the KSU, the system will not boot up.
The other hand CHS2U B-xx (Base Chassis) has the capability to expand 3 more slots by side
connection of CHS2U E (Expansion Chassis).
Communications between legacy stations / trunks and DT700 series telephones / IP networks are
made using a VoIP board, which converts packet-based voice data to TDM-based voice data, and
vice versa. Both peer-to-peer connections and TDM-based connections are controlled by the CPU
board. The CPU incorporates a built-in Device Registration Server (DRS) and a single interface
point of IP connection to IP telephone, PCPro and OAI / ACD servers.
