But finding a transformer with one primary and many secondaries (*Don't try one big transformer, BAD things will happen to your modems involving smoke) to power your non-rack-supported modems is really tough. the time I spent dealing with electronics suppliers and the prices I was quoted; well, I could have just bought a few Ascends... The Courier solution sounds really nice for 50-ish modems; one could even put big PBX connectors on the back to tidy up the phone lines, and Xylogics now has optional cables that keep the 6 RS232's together and just terminate in another PBX-style connector. A handy person could make a neat cabinet with alot of spare time. But I still like the idea of a rack that can "take care of itself" and busy lines when a modem fries. None of the individual modem solutions offer this, and while the Couriers that we have perform extraordinarily well (only one has bit it in 2 years), they are pretty pricey when compared to an all-in-one, plug-some-T's-in-the-back-and-go solutions. Used equipment can be a good thing. Charles
