The user's modem is set to connect within a certain speed range through an init string. The speed was unable to be negotiated. If S48.0, S48.1, or S48.2 is used to disable 300(v.21), 1200(v.22/v.23), or 2400(v.22bis/v.26/v.26bis/v.26ter) and the modems could connect at any higher rate. Try fixing the user's rate, or changing the acceptable rates of the TC.
