ENERAL
ECTION
The SV8100 is a full-featured IP based communications system providing
a rich set of existing system features, with pure Voice over IP (VoIP)
communications, across corporate Local and Wide Area Networks (LAN
and WAN).
The DT700 series telephones provide a converged infrastructure at the
desktop, with a 10Base-T/100Base-TX connection to the LAN and built-in
hub for a PC connection to the telephone itself. The system can provide
peer-to-peer connections between the DT700 series telephones with voice
compression, offering existing IP telephone features with an enhanced
user interface. On the WAN side, the system can provide peer-to-peer
connections over IP networks with the voice compression, on CCIS over
IP.
The SV8100 can provide legacy line/trunk interfaces to support the
existing Time Division Multiplexing (TDM) based infrastructure, such as
analogue telephones, digital telephones (DT300 series), analogue
networks and digital networks (T1/E1, ISDN, etc.).
The 9.5" Gateway or Base chassis provides 48 total ports (32 digital
terminals) and can include any combination of stations and trunks below
this number. (AU Only)
The 19" chassis provides 111 total ports (80 digital terminals) and can be
expanded, using three additional 19" chassis, for a maximum of 444 ports
(368 digital terminals). Through IP connection and four additional 19"
chassis, the system can be expanded to a maximum of 512 ports for
SV8100(refer to
System Capacities – Trunks/Ports/Channels on page
Communications between legacy stations/trunks and DT700 series
telephones/IP networks are made using a VoIP daughter 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 blade. The CPU incorporates a built-in Device
Registration Server (DRS) and a single interface point of IP connection to
