Have you been using synchronous modems to connect two synchronous DTEs, even though the distance between them is negligible? If so, the Patton Model 1200 synchronous modem eliminator can save you lots of money! Installing between the DTEs, the Model 1200 synchronizes their clocking and matches the wiring.
