66/110 blocks - newbie question |
|
|
Seriously newbie ignorant question. If that offends you, read no
further.
I'm asking for help in verifying that my basic grasp of 66/110 blocks
is corrrect.
A 66 block has metal contacts arranged in 4 columns. The outer pairs
of columns are connected across. To connect ("terminate" just doesn't
set off the right thoughts in my brain) wires you punch them down on
the outer columns. To connect wires in the block horizontally you use
small metal clips on the inner columns. To connect them vertically you
punch down jumper wires right on top of the original wires.
A 110 block is just a piece of plastic with grooves/receptacles for
clips, in two columns or rows. You attach/make ready wires by punching
them down into the block. To make electrical contact to the wires
available you punch down clips on top of the wires, either with a
special tool or with multiple impacts of the simple punchdown tool you
used originally. To make any connections between wires in the block,
horizontal or vertical, you punch down jumpers on top of the clips.
Thanks for the help. |

A 66M1-50, one of the most commonly used, indeed, has 4 rows by 50
pins. The pins are paired 2x2. An M1-25 is 4 rows all wired the
same, and B blocks are 6 rows across 3x3 for the 50 and 6 across for
the 25.

No. You only get one punch per pin, but you can connect something to
the inner pins before you use bridging clips.

Yeah, that's it. A multi-punch tool does a better job of seating the
110C clips, but in a pinch a block of wood or carefully punching both
ends with a single tool will work.

Depends on which 66 block you're talking about, as their use is
not limited to LANs and single-line voice circuits. They formerly found
wide use with the older 1A2 key telephone systems. In fact, usage of 66-
series connecting blocks dates back to the 1960's.
The 66M4-25 has 50 rows of six parallel-connected (across each
row) clips. The last column of these clips faces the opposite direction
of the others.
The one you're most likely to see today is the 66M1-50. These
blocks, also known as 'split' type, can accommodate 50 pairs (100 wires
total), 25 pairs each side. Although they have four columns, said
columns are electrically split right down the middle.
In other words, the first two columns of each row on the left side
of the block are electrically parallel with each other. The second two
columns of each row on the right side of the block are likewise parallel
with each other. HOWEVER -- The rows are NOT electrically connected all
the way across unless you install bridging clips to make them so.
66 blocks can only accommodate one wire per clip. However, you can
get stack-on widgets with extra clips. I don't recommend these for LAN
use, as they can introduce quite an impedance bump. Come to think of it,
I wouldn't use 66-blocks for anything above 10Base-T, period.

Yes and no. There are different punch-blades for 66 and 110
blocks. A good-quality punch tool should need no more than one punch per
wire, assuming it's held correctly and the block itself is in good
shape.

That sounds right. The clips have connecting slots on the front
side.

You're most welcome. Are you also aware of the standard telephone
cable color code?

In all my years of experinece, I've never seen two wires punched down on
a single terminal, except by mistake. If two wires are on a single
terminal, one of them will make poor contact and be noisy or
intermittent.

You are a spammer, specializing in polluting Usenet newsgroups
with useless off-topic drivel.
The Internet in general, and Usenet newsgroups in particular, are
not your personal advertising playground. Take your spam and blow it out
a Krone block.
