Hi,
I have a router which dials a central site with 2 ISDN lines (4 B channels). If the highest interface (BRI 1/1) becomes disconnected/faulty the other wont connect at all.
When the two lines are plugged in and working OK I notice that the dialer starts with the highest BRI first and works its way down the interfaces. If the first one doesn't come up neither do any others. How can I make this happen so I at least get 128K in a possible fault scenario. If I admin down the bri1/1, 1/0 come up no probs. Its only when the line is at fault or the cable is unplugged I see this problem.
IOS 12.2(8)T4
Thanks.
