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?

Keystone jacks aren't designed to allow that, so that is why you are
getting static (and probably no data will work at all in that setup).

A pro would rip out all the daisy-chained wire, and wire homeruns from
the demarc out to each station. One run, end to end.

Yes, you sometimes have to creative fishing wire, or know how to redo
drywall and repaint. :)

Rewire!  That's what the pros do.

You have a problem with the punchdowns because you have an even more
fundamental problem with the wiring layout:  the phone wiring you
describe is the standard, common daisy-chain.  The NID box wired to the
first phone, then one phone to the next.  This works for analog POTS.

Data (other than obsolete coax like 10base2 and 10base5) requires
star-topology wiring (no up/downstream) -- each outlet having a
dedicated wire run to a central "head-end".  Also works for POTS
but takes 3-5x more wire.

With cleverness, it might be possible to break into the daisy chain
and reuse a run or two (max per break).  Some places can be very hard
to rewire without disturbing wall finishes.  For short residential
runs, the quality (Cat) of the wire is less important than having
the necessary pairs (one pair for POTS, two for 10/100 data).
