I am trying to understand how we are supposed to fit a pair from two separate shielded cables into a single plug and not have it look kludgy. Also, what do we do with the extra pairs? Also, it seems that connectors 7 and 8 are supposed to be used for grounding. When the Telco terminates it's T1 into an RJ-48X jack, does it usually ground connectors 7 and 8? If we use shielded cable, how do we go about connecting the shielding as well as wires 7 and 8 to connectors 7 and 8 in the modular plug? Can we use ordinary 8p8c modular plugs for T1?
