Hello,
25-pair color code attached below; from a post I had tucked
away.

Remember:
Bell Operators Give Better Service
Blue (1,6,11,16,21) Orange (2,7,12,17,22) etc. Green Brown Slate
We ride big yellow vehicles
White (1-5) Red (6-10) etc. Black Yellow Violet
Thus pair one is
white/blue
pair five is
white/slate
pair six is
red/blue
etc

I need to get the standard color codes used for 25 pair bundles of
telecom cable.
Does anyone have it handy to email to me?

This wont help anyone but I had to post it as a question to the above.
HOW THE HECK DOES NYNEX KNOW HOW TO WORK WITH A 400 WIRE CABLE ?.
They dropped 200 pair in my store for my ISP business and they went right
in and wired up the two big telco terminals like they were knitting
socks. No manuals, no charts, nothing.
Is there a way to know what wire belongs to what, how does a splicer
know how to work one of those cables?.

In a multi-hundred pair cable the zillions of wires inside it are
grouped together in what is known as "binders", ie a thin ribbon of
colored plastic that encircles 25-pr groups. If you watched closely
when they laid open the cable sheath they were careful to 'preserve' the
integrity of these binders and likely tied the bundles off in 25-pr
groups while they worked with the others, one binder at a time.
In a 400-pr cable there will be 16 binders (25pr in each). Each binder
being a different color (Blue/orange/green/brown/slate, etc., per the
established color code) The 'binders' are not a separate inner sheath,
merely a single strand of colored plastic wrapped around the 'group' at
about 2-3 wraps per foot of length. To the uninitiated novice carving
into a 400-pr cable for the first time in his life, he'll be overwhelmed
with the maze of wires. To a cable installer who makes his/her living
doing this day in and day out, it truly is like knitting socks. No
manual required.

Check this page out, http://www.hubbell-premise.com/110blkwr.htm.
Multiples of 25 pair bundles are coded individualy (blue, orange, green, brown, slate)
in their own coloured wrapping (so you break them out one bundle at a time and start
over with the same 25 pair colours).
Hope this helps...Mike

individual members of these groups are blue, orange, green, brown, slate.
So the first group of five is
blue/white Pair 1
orange/white Pair 2
green/white Pair 3
brown/white Pair 4
slate/white Pair 5
followed by
blue/red Pair 6
and so on.
So pair number twelve would be orange/black
Each 25 pair group is called a binder and around the first binder you'd
find two nylon strings (also called binders), in this case being colored
blue/white. So, the eighth binder (8*25=200) that was installed by your
RBOC had a green/red binder.

Its just second nature to someone that does it day in and day out, you don't
even think about it. I can even confuse them more, I learned how to punch
down a 25 pr cable from an oldtimer that started from the bottom -
because if you do it from the top down, everything you put down is in
your way - If you do it from the bottom up, nothing is in your way.
You just have to remember that the LAST pair is the violet/slate.
and the "backwards" color code is Slate, Brown, Green, Orange, Blue and
the groups "backwards" are Violet, Yellow, Black, Red, White.
Punching down a 66 block "backwards" ( from the bottom ) can cut 10 to 20
percent off the time to do it. 100 pr per hour from the top down and 125
pair per hour from the bottom up.
Now you know this is not going to be true the first couple times you do it,
but give it a chance.

Good idea Don, I just make sure the cable comes in from the top, even if I
have to put a loop in it. I guess it does the exact same thing. This also
leaves the "next guy" a foot or so extra just in case.
Cheers!

I agree wildly; the TOP ---> BOTTOM thing makes my back spaghetti, fingers
spoony and my head spinning. Always BOTTOM ----> TOP for me!
I usually use the KRONE connector, with that the extra length makes itself
all the way, so I don't have to think about if the cable comes from top or
bottom. The extra twenty cm (apx 8 inch) are always there for the next guy...
Where I work (Norway) we have another standard too, though: It makes groups /
binders in ten-pairs:
blue / red blue/black (pair 1 and 6)
white / red white/black (pair 2 & 7)
yellow / red ylw/blk (3&8)
slate / red slate/blk (4&9)
orange / red org/blk (5&10)
The plasticbinders follow the groups with the same colour code up to hundred.
Then the greoups are binded in fiftys (for small cables = less than three
hundred pairs) and hundreds, wich makes it really easy to pick up a 2000 -
pair and knit it like a sock...
Cheers!
Ha en god dag, / have a nice day,
Lars.

Some of the older cables (ie, paper insulated.. egads!) are a real charm to work
with. Each pair has to be individually toned-out (although, current tools make this
easier nowdays), as there are NO colours. OK, I lie.. the 100 pr groups are coded in
layers (from the core out) so you can usually ID the group easily.
As to pic cables.. after 600 pairs, we run out of binders (actually 625 would make
the violet-slate binder). Different companies seem to approach the excess in
different ways. Most seem to make the 626-650 binder white-blue-red, the 651-675
white-orange-red and so forth.
Agreed though.. it does look wild, but it's mostly just "knitting socks".
