I have a point to point line between our UK and US office. I am pretty sure the config on the US side is good, however, I am not sure about the UK side. I just realized that I may have the wrong card, as British Telecom's equipment is saying that the speed is 1536. I have a VWIC-1MFT-E1 in an 1800 series router but I can't get the serial interface up. I have tried many different configs...am I missing something? Could someone shed some light on this? Thank you very much.
