Re: Need 66-block help. 1 POTS line, 8 jacks


For the uplink to the demarc, there is 1 pair of wires. From the top
of the 66 block, I ran one of these wires down the far left column and
the other down the far right column, punching down the first 8. I then
took one of the phone jack lines, used the blue and blue-white wires
to punch down to the 2 center connections on the top row. I have a
dial tone for the jack, but......

No, this is not the right way to wire up a block. You'll have a rats nest on your hands trying to get all the handsets wired into that left/right row mess.

What you should do, as Lewis suggested, is punch all the wires from each handset down along one side. Then punch a line down along the other side for each tip/ring pair needed. The use the metal bridge clips along the center to carry the signal over from one side to the other.

This will mean you'll punch the incoming line from the demarc down at one point and then run a pair of lines for each of the 8 handsets. It's not uncommon to take a wire and punch it THROUGH a connection instead of terminating it there.

If you have a real punchdown tool you'll notice it has two sides to the tip. One has a cutter blade and the other doesn't. It's that second side you use to punch down a line without cutting it.

Using that dull side of the punchdown tool you can use a longer section of wire and loop it from one post to another. If you've terminated all three pairs from your handsets you'd loop the wire to each active post and skip over the unused ones.

And make note, your DSL modem has to get a clear line directly from the demarc. But your handsets shoud NOT get this same line. The handsets should ONLY get a line that's been through a DSL filter first. You can use just one filter.

What I've done before is wire a pair of jacks near the block and put a filter in between them. They make fancier ways to do this but a plain old in-line filter and a pair of boxes is often a lot cheaper.

So bring the pair in from the demarc to the block. Run one pair to the DSL modem's jack. Run another out to the filter. Then run that pair back to the block and distribute it to the handsets. If you need to use another handset at the DSL modem then remember to put a filter on the line after the modem.
