He told me that he had called the numbers at each end and discovered Telebit modems. Quite right. He then proceded to explain, in great detail, the problem with CCITT- compliant echo suppression and the Telebit's inability to reliably disable them. He talked frequencies, timings, and asked further questions about the difficulty. We talked for about ten minutes, and after our conversation I was convinced that the problem lies within the firmware in my modems. Of course, the immediate fix is to use another carrier (such as AT&T) where this problem doesn't occur. The long range fix is for Telebit to modify firmware so that their modems can successfully disable echo cancellation on CCITT-compliant systems. Since Telebit is in the local area, I will now direct my complaints in their direction. Sprint has finally done what I would minimally expect from a company that has aspirations to greatness: looked at a problem and discussed its solution with a customer. I am satisfied that although I may not be able, for the present, to utilize Sprint's services, the company is providing product in good faith. My only beef with Sprint at this point is that it took them a week to come through with an explanation. Maybe that will improve with time. John Higdon | P. O.
