Request for input:
I am considering purchasing Multitech's 2400 baud modems (224's) to serve on
the dial-in ports of a uVAX system (via a Micom port selector). My major rea-
son for purchasing 2400-baud units is to provide better noise "supppresion"
for our dial-in users, most of which are using 1200-baud Hayes units.
I would appreciate comments from people re: a) the quality of the MultiTech
modems themselves, b) the transparency (to software and hardware) of their
substitution for Hayes units, and c) alternatives to the MultiTechs.
Our major concern is to provide decent connections to long-distance callers,
many of whom experience noise problems. Our second concern is that we would
like to be able to replace the existing Hayes units with a minimum of effort.
thank you, greg pavlov, fstrf, amherst, ny

We are using Multi-Tech and have been very happy with them. We have over a hundred (I suspect way over, but I don't have the figures), and we have been very happy with them. They seem to be more Hayes compatible than Hayes 2400, since you have the option of not generating a bunch of "enhanced" messages. I don't know if they're the best, but they have been very good for us. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me

I recently received a flyer from American Digital for equipment including some MultiTech modems. Being in the market for a new modem, this was of some interest. They list the following external modems: 224EH 2400bps with MNP 3,4, & 5 $299 696EA 9600bps V.29 with $475 MNP 3, 4, 5, & 6 V.32EA 9600bps with Error Correction, $630 & MNP 3, 4, & 5 The questions I have are: Are these good prices for these types of modems? Would the V.32EA be a good choice for a dialin/dialout port on a Xenix/386 v.3.2.3 system? What about the 224EH? What is going to happen to MNPx protocols vs. CCITT standards? What are most peoples experence with Multitechs? Does anyone have a phone number &/or E-net @ for Multitech?

We have used Multitech for over a year now and have installed them at several client sites. We have found them to be an excellent product. They are easy to configure because help screens can be brought up to describe the various settings with your current settings along the bottom of the screen. There are many more options available to configure than I have seen previously. For example, we installed a communication system between a head office and two branch sites in different cities. Using uucp, accounting data files were to be transferred at night from the branches to HO. One branch went fine. The other one was a nightmare! Everytime we tried calling the site, the modem would answer, then garbage characters spilling all over the screen. After exchanging the modem (696EA ?) bringing the computer into Vancouver where everything worked fine, I finally called Multitech. I should have done that first. I described the symptom and the analyst researched a database and found something similar. He said it sounded like the phone system in the branch city was causing the carrier to be received too strongly and an echo was being seen by the getty. He suggested lower the dB strength of the calling modem by setting one of the S registers. This capability wasn't even documented. By lowering the dB strength of the carrier he thought that the echo would be reduced. Guess what? It worked...first time! I believe that if we had been working with any other brand of modem we would have had to do open heart surgery on the straps inside the modem, if we could have done anything at all. That branch has been transferring about 4Mb of data every weekday evening for over six months now and we haven't had one corrupt file using their auto-reliable MNP error correction. Great modems and good free support. > Does anyone have a phone number &/or E-net @ for Multitech?

We have over 100 of the 224e's rackmounted. I have recently added 8 of the 932er 9600 baud and they are working well. The reiliabilty of all of these is very. Also the tech support people are very good. They are very responsive and helpfull with problems. Even odd ones.

We use them and have had good luck. Your prices are right in the ballpark. We
get them for a little less but not that much less. I recommend that you get
the v32 if you want 9600. We have been using them for about 2 years and have
bought 50 or so. We also have been using the mt224e 2400 modems with good
results. Easy to configure, easy to use manual and extremely reliable.
REMEMBER MODEMS ARE BLACK MAGIC AND YOUR RESULTS COULD VARY DUE TO PHONE
LINE QUALITY AND WHICH WAY YOUR DOG IS POINTING AT ANY GIVEN MOMENT :)

Not to knock Multitech's support, but if you had been dealing with another brand of modem, the register you needed to set might also have been documented, which would have saved you a lot of grief. -- Alan Groupe | Data: (603) 672-9662 2 Great Brook Road | uucp: decvax!ubbs-nh!trashbin!alang Milford, NH 03055 | alang@trashbin.mv.com (603) 672-9155 | "I'm not a liberal, so I have a poor grasp of | things I know nothing about." -- P.J.
