How would the pros punch down two phone lines at one keystone jack? The ph= one lines in my home are run in series / serial. Phone line comes into the= wallbox (some newwork; some oldwork), then goes out from the box.
I am installing a wired network in my home including converting all phone-j= acks to keystone -- using Cat6 for data and Cat3 for phones. I tried punch= ing down a 'double-punch' of both the upstream and downstream wires to the = same slot, but that seems a kluge and some resulted in static when I pick u= p the phone. =20
Given that mine are basic phones that use no more than four wires, a keysto= ne phone coupler jack (four slots for in; four for out) would be a solution= , but found none. Plus, jacks are 110-block, and I assume 66-block clips w= on't solve this. Maybe a junction of some kind upstream from but nearby th= e jack? What would the pros do?
