Does anyone know what document describes the standards for installing STP?

Like ALL cable shields, it must go straight to the shielding enclosure at each end to be effective. I don't work in the computer networking world, but I have seen shielded CAT5/6/7 patch cables. They are terminated with connectors that have a metal surround to mate with similar female connectors.

It must be remembered that each end of an Ethernet is a potential noise source, so shielding and suppression are needed at both ends. Remember also that an Ethernet cable can also be carrying RF trash in addition to that generated by the Ethernet line driver.
