Highlights
USB
Freedom. The MultiModemISDN USB model gives you
a greater level of freedom because it installs and hot swaps with
other USB devices without restarting your computer. In addition,
gaming and multimedia applications get a performance boost with
the 12M bps USB port.
Simultaneous
Voice and Data. Transmit/receive data on your computer
over one ISDN B-channel and use the other B-channel for your phone
or fax machine using the analog port.
Dynamic
Bandwidth Allocation. Use the full bandwidth and
still be able to make and take calls. The MultiModemISDN can combine
channels for maximum 128K throughput and when traffic is low or
an analog call (voice, fax, or data) comes in, one of the B-channels
can be dropped.
Easy
Installation. With MultiModemISDN serial models
youˇ¦ll be up and running in minutes with Windows Plug and Play
and an installation wizard that walks you through the configuration.
The USB model boasts the easiest modem installation on the market
today and is auto detected by Windows.
Complete
WAN Protocol Support. With support for a full-range
of WAN protocols, including PPP, ML-PPP, MP+™, V.120, X.75,
CLEAR (synchronous), CHAP, MD5 and PAP you can connect to a variety
of servers on the corporate LAN or Internet.
