Re: Newbie: Punch down block 66 vs 110, how do these work?

My home has a punch down box in it installed by the phone company. It
is much smaller than those I see called 66 or 110. The box has four
rows and six columns. I can see that all the connections on this punch
box block have been used up. I want to add some extensions and wish to
replace this punch down box with a larger capacity one.

I assume you have a varient of this punchdown block.. (The Suttle
A66B63 if the page ref doesn't work).

Except only 2 pair usable instead of 3 pair usable.

This is a 66 style block. The 66 or 110 is mostly the type of pin, and
the punch down tool blade you'll use. There's specific models of 66
blocks that are very standard parts. 110 is a bit more freeform, and
is popular due to their use in datacomm connections. (I actually
prefer 110 for voice, but I'm in a minority around telco cabling
circles. Maybe its all the times I've brushed past uncoverd 66-blocks
and got zapped.. ) You see alot of 110 in structured wiring cabinets
now too.

Now my understand how this 4 x 6 punch down block works is that each
row shares the same wire connection to any of the terminals(?),
usually connected from the other ends, but I guess it doesn't matter.
I don't know if this is a 66 or 110 style punch down box, although I
don't know if this matters.

Yep you've got it, the incoming pair gets split across the first and
second rows. The home-runs will get punched down going across in
order. All the pins of the row are tied together. If you have two
lines coming into the house, then your first line will be on the first
two rows. The second line will be on the third and forth rows.

I have looked for larger punch down boxes, but all I can find in the
stores is either the 66 or 110. The 66 made by Leviton is "66 Block,
Split M, Clips Included". This one has four terminals across and 50
rows. I'm confused, how can I use this to take advantage of adding
many extensions in the home for lines 1 and 2? I see this has clips
included, but I don't understand how these work. How does this work?
Can you connect the 2 wires for line 1 to the first two of the four
going across, and the 2nd line for the next two, and then be able to
add as many as 49 extensions to this?

There's alot more out there than the home-centers carry..

The 66 block you've found works different. It expects that you
terminate both your incoming and home-run lines seperately, and then
jumper them all together with more wires. You would have to
daisy-chain your line down the block connecting your pairs together.

If you go online, with some of the other options there, you may find
more to your liking. Ie. the ETCON DD1C works much the same way as
your 4x6 block, each incoming line pair gets attached to the vertical
runs down. Your homerun stations come in and get punched down on the
appropriate line. You get twelve here, although you can bridge
together two rows and get alot more density.

If you want to learn how to wire the 66-block you saw, here's a good
webpage that explains how to daisy-chain it.

He also has a scheme for daisy-chaining 110, although I do it different.
