I suppose you could try to create some electrical disturbance, like running
the cable near florescent lights, or wiggling the connector constantly to
create a lot of errors. It's definitely easier to do with UTP than a serial
cable. HTH.

Anything to disrupt the signal will do. Are you talking about a
crossover
cable and DSUs, or just a DCE-DTE serial cable?

Does anyone have a way of generating T1 errors with back-to-back serial
cables if I wanted to test LQM in the lab?

How about using PPP encap on the T1 with LQM.
