If you have a TELES S0 USB box (phantom powered) connected to your ISDN line this problem may appear now and then, disturbing outgoing B-channel data. Most likely some device is sending bytes different from 0xff to a B-channel when not in use. The HFC cards are cheap, and work well in PPP mode, and have been checked against this problem. The PCI version is not yet supported, if you are not running current, with the latest new_ihfc driver installed. > > Which hardware/driver are you using?
