In evaluating 2400 bps rack-mount modems for regular dial-in and uucp dial-out use, we've narrowed the list down to the Concord Data Systems CDS-224 and the Multi-Tech MultiModem-224. Both are in the $400-500 per card price range and seem to have all the standard 212A/V.22bis features. Both claim Hayes compatability (which isn't something I would brag about myself). The Multi-Tech has optional class 3 MNP error correction. Anybody out there have experience with either of these units (good or bad) that they would like to share? I'm especially interested in hearing about the Multi-Tech because I've never heard of them before a couple of weeks ago. -- Roy Smith, {allegra,philabs}!phri!roy System Administrator, Public Health Research Institute 455 First Avenue, New York, NY 10016

Multi-Tech is a small company located in New Brighton, MN, just outside Minneapolis. They have been around for about ten to fifteen years now and have specialized in commercial and industrial modems. We bought a MT212AH 1200-bps 212A-compatible modem from them a few years ago. It is obvious from its design that they have not had much experience in the consumer market. The DIP switches all come configured so that the modem could be connected to a mainframe for dialup use, which is not always ideal for home use. They have since gained experience at building consumer-oriented modems, but this is probably irrelevant since you are looking at rack-mount stuff. Since we bought one of the first MT212AH's, we did have some trouble with the auto-answer circuitry after a few months. We took the modem back to the factory, where they not only fixed the problem, which probably only took a few minutes, but also replaced the lithium battery, updated the PROM's, replaced plug-in AC transformer, and modified the amplifier circuit for the built-in speaker to increase the volume. This was all under the one-year warranty and cost us nothing. -Ross Snyder
