Thanks for the details. Is it possible for me to get a
pair of VWIC-1MFT-G703 (one each on two different
2621) to talk to each other so that I can do some
testing?

I know it is possible to do a back to back cross over
between "normal" serial interfaces like that found on
the 2514 and WIC-2T. But what about the
VWIC-1MFT-G703? Anyone tried before using RJ45 cables
to connect routers back to back? Any special settings
to look out for?

Thanks,
