I could probably work There are many such products. Most use a statistical methodolgy, and some can do dynamic load balancing over two lines if the traffic warrents. The product we use here is produced by Multi-Tech. We get 16 serial ports into the box, run it over a leased line to Austin, and have the matching box on the other end. We are not currently using all sixteen ports, but wanted the option. But most of the vendors have four line boxes just as you have shown. Mutli-Tech even lets you choose between their internal modem, or your own external modems. Shop around a little. These things are quite common, and I'm certain that you can find one in your price range. +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=+ | Honesty is in the eye of | Phil Meyer | | the creditor. | Usenet: !attctc!lodestar!phil | | | VoiceNet: (214) 991-0897 | +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=+
