Is this true, > or just rumor? I send all of my night Southern California uucp traffic over Sprint using Telebit modems. There began to be major throughput problems and even conversation failures. Many calls to Sprint finally netted a response that the company was now using CCITT-compliant echo suppression and that they were aware that certain Telebit firmware releases did not adequately cause the echo suppressors to drop off. After reading my many postings on the topic, Telebit contacted me and offered to upgrade my modems. They sent new firmware and since then there has been no more trouble of any kind on Sprint. To my knowledge, the HST modems never had any problems; this was strictly a Telebit Trailblazer+ phenomenon. In no case is this a bandwidth problem, or even a "slippage" problem. John Higdon | P. O.
