ENERAL
ECTION
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.
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 104 total ports (80 digital
terminals) and can be expanded, using three additional 19" chassis, for a
maximum of 416 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 and a maximum of 1024 for SV8300 (refer to
2-2 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.
