Introduction to ISDN-BRI MultiVOIPs
(MVP410ST & MVP810ST)
VOIP: The Free Ride. We proudly present Multi-Tech's MVP-
410ST/810ST generation of MultiVOIP Voice-over-IP Gateways. All of
these models allow voice/fax communication to be transmitted at no
additional expense over your existing IP network, which has ordinarily
been data only. To access this free voice and fax communication, you
simply connect the MultiVOIP to your telephone equipment and your
existing Internet connection. These ISDN Basic Rate Interface (ISDN-
BRI) MultiVOIPs inter-operate readily with T1 or E1 MultiVOIP units
(T1 and E1 MultiVOIP units can operate in ISDN Primary Rate Mode,
ISDN-PRI, as well).

Capacity. MultiVOIP model MVP810ST accommodates four ISDN-BRI
lines (eight B-channels) and model MVP410ST accommodates two
ISDN-BRI channels (four B-channels). Both of these MultiVOIP units
have a 10/100Mbps Ethernet interface and a command port for
configuration.
Mounting. Mechanically, the MVP410ST and MVP810ST MultiVOIPs
are designed for a one-high industry-standard EIA 19-inch rack
enclosure. The product must be installed by qualified service personnel
in a restricted-access area, in accordance with Articles 110-16, 10-17, and
110-18 of the National Electrical Code, ANSI/NFPA 70.
Phone System Transparency. These MultiVOIPs inter-operate with a
telephone switch or PBX, acting as a switching device that directs voice
and fax calls over an IP network. The MultiVOIPs have “phonebooks,”
directories that determine to who calls may be made and the sequences
that must be used to complete calls through the MultiVOIP. The
phonebooks allow the phone user to interact with the VOIP system just
as they would with an ordinary PBX or telco switch. When the
phonebooks are set, special dialing sequences are minimized or
eliminated altogether. Once the call destination is determined, the
phonebook settings determine whether the destination VOIP unit must
strip off or add dialing digits to make the call appear at its destination
to be a local call.
