Chapter1; Introduction to SV8100

SECTION 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).
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 or Remote Unit over IP.
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 (T1/E1, ISDN,
etc.).
The new compact 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
SV8100 Maximum 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 IP telephone, PCPro and OAI / ACD servers. Figure 1-1
shows a simplified view of SV8100 system connectivity.
