Hi guys/dolls I have the following 3Com ISDN modem and whenever I configure it to use both B-channels, I can't get onto the AS5300, but whenever I have one B-channel configured, I connect perfectly. Any ideas?? 3COM OFFICECONNECT ISDN LAN MODEM Product # : 3C891 Model: ISDN LAN Modem Connection: ISDN/ST. Analogue and Ethernet __________________________________________________ Do You Yahoo!?
