I honestly have never tried leaving the Y-Cable in on critical links... normally I do this stuff on an outside-contractor basis from the perspective of the "company" (my client). I offer outside services at a Communications company, my job is to design, install, and troubleshoot networks for many clients. As a result, I only have 1 Y-Cable V.35 for the Internet Advisor, and it always leaves with me, when the unit is no longer used. I will try to research this in a lab, and let you know what conclusion I come up with.
Now I know what I am going to fill my 2 spare hours with tomorrow morning. On October 2, 2001 01:53 pm, Dan Faulk wrote: > Hey learn something new every day on this list, good info.
