For short runs, the use of cat5 vs proper T1 cables isn't likely to
have any impact unless there is a fair amount of induction from
electrical noise, etc. That can take the form of florescent fixtures,
transformers, older CRT monitors, etc, etc.
On longer runs, the shielded T1 cables are likely to provide better
results particularly if there happens to be any electrical noise.
Oh, and if shielded T1 cable is used, the shield at each end of the
cable must be grounded. (Let's see how many can figure out how to do
that via an rj45 plug. ;)
Totally agree with you, unshielded cables are only usable if the
distance is short. Just curious, how should one ground the shield? Do
you ground it to the ground bar in the server room? Any special
requirements?
That would be one way to do it, at both ends.
Personally, I would not try to install an rj45 on each end of a shielded
T1 cable, but rather terminate the cable on a patch panel.
