ENERAL
ECTION
The SV8100/SV8300 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/SV8300 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 (320 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
Maximum System Capacities – Trunks/Ports/Channels on page 2-4
Table 3-2 SV8300 Maximum System Capacity on page
Communications between legacy stations/trunks and DT700 series
telephones/IP networks are made using a VoIP blade, 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 is a simplified view of SV8100 system
connectivity and Figure 1-2 is a simplified view of SV8300 system
connectivity.
