I need a cable to connect those devices. A straight-through doesn't work, nor do the two types of crossover cables. Apparently the other vendor got with comcast on the phone and they worked it out real time. Comcast is supposedly going to get in touch with me on it, but I'm wondering if anyone here happens to know what would (or have a good chance to) work. Thanks. -Frank
Never mind. It's a standard T-1 crossover cable. Comcast is a bunch of poseurs. Thanks very much to Adtran tech support, who answered the question in five seconds.
