Tim,

You say your using 1.424M, this is not a common speed for DSU's that I have 
worked with in the past. 
What kind of line encoding does GTE have setup for you?
Is it possibly AMI?
If it is AMI and you are using HDLC, then I would suggest inverting the data
at the DSU. This will garuanty your 1's density.

The thing that bothers me the most was you said you have a cable that goes from
RS449 (39 pin D conn.) to a DB25 conn. Do you know if this is actually an RS530
interface or is it some modified hybrid?

If you are still having problems, please feel free to send email to tac@cisco.com
and a case will be opened for you. If you include the info I asked then it will
help speed the troubleshooting of your problem. Please also include "show hard",
"show int ser x" and "show cont mci".


I hope some of this helps. (-:
