ENERAL
ECTION
The SV9100 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/DT800 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/DT800 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 SV9100 can provide legacy line/trunk interfaces to support the
existing Time Division Multiplexing (TDM) based infrastructure, such as
analog telephones, digital telephones (DT300/DT400 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.
The 19" Base and Expansion (Combined) chassis provides 104 total ports
(80 digital terminals) and can be expanded, using three additional
combined chassis, for a maximum of 416 ports (368 digital terminals).
Through IP connection and four additional combined chassis, the system
can be expanded to a maximum of 960 ports for SV9100 (refer to
2 SV9100 Maximum System Capacities – Trunks/Ports/Channels on page
2-5).
Communications between legacy stations/trunks and DT700/DT800 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
