Microcom says that its new QX/2400t modem with MNP 10 is the
highest-performing V.22bis unit on the market. It uses the data
compression of MNP 7 to achieve transmission speeds up to
12,000 bps (bits per second) under optimal conditions, Microcom
says, and, with the added features of MNP 10, can accommodate
dirty phone lines, signal fading, and other interruptions.
 
The latest in a series of Microcom Networking Protocols, MNP 10
works with the compression features of the widely-used MNP 5 and
7 standards, which provide double- and triple the data rate
through software.
 
Class 10 adds what Microcom calls ACE, or Adverse Channel
Enhancements, that automatically change transmission speed and
packet size depending on the line quality. These improvements are
especially useful when signal clarity fades in and out, as in
cellular links, or for international transmission using outdated
analog switching equipment, Microcom says. A feature of ACE
called Robust Auto Reliable also provides backward compatibility
with non-MNP modems.
 
Price: $699.
