Hi, I was hoping someone might be able to help me with the following problem. We have a customer with a rockwell modem that is unable to connect with error 645. In our RADIUS log it shows that they are authenticating ok, but the detail log shows a 300bps connection with a modulation type of Mon Jul 15 12:45:38 2002 Acct-Session-Id = "00000017" User-Name = "adams175" NAS-IP-Address = 216.169.164.167 NAS-Port = 27 Acct-Status-Type = Start Acct-Authentic = RADIUS Called-Station-Id = "2725501" USR-Connect-Speed = 300-BPS USR-Modulation-Type = ccittV21 USR-Simplified-MNP-Levels = 0 USR-Simplified-V42bis-Usage = 0 USR-Chassis-Call-Slot = 0 USR-Chassis-Call-Span = 0 USR-Chassis-Call-Channel = 1 USR-Unauthenticated-Time = 43 NAS-Identifier = "tc01-gw" NAS-Port-Type = Async Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = 216.169.164.181 Acct-Delay-Time = 0 Client-IP-Address = 216.169.164.167 Timestamp = 1026751538 Request-Authenticator = None Some more details: Total control with Quad Digital Modems and Netserver card running PRIs ...I don't have the software revisions handy at the moment but can check on it if need be. The only thing I can think of is that their modulation might be set to V.21?? I'm having someone contact them to check that out, but thought I'd post anyway, as I doubth this would be set incorrectly. Any help would be great appreciated. Thank you, Daniel S.
