satpir. PLEASE DON'T YELL :toast:

I am also confused by this...If we had to extend a T1 with Cat 5 to a biscuit jack, would we term w/b & blue,then w/o & orange, isn't that pins 1,2,4,5 on the patch cord?

In other words is the w/b and w/o still considered (tip) and my orange & blue still considered (ring) and as long as I do not terminate on my w/g (pin 3) I should have proper functionality, right?

Well like the others have said, you want to use a jack with the shorting bars, not just a standard 8p8c jack. You would just use the blue and orange pairs.

As SATPIR [not yelling] was typing...

"This RJ jack is RG48X, whAT IT HAS IS A SHORTING BAR..."

You will notice that everything typed after the letter "A" in the word what, or as typed "whAT" Let me see...what key is next to the "a" key?

Do I perhaps see a key with the letters...

Caps Lock

OMG...also know as "Oh my, God!*"

*God, god, gosh...et cetera

I think the culprit satpir is guilty of nothing more than hitting [Add Reply]

So now we should all either have a "GROUP HUG" or "DAMN HIM TO HELL"

...can you hear me now? :rofl:

I love this plaCE...i IS SO MUCH FUN!

It was also more than two years ago. :scratch:

ok, my scenario is I have a Verizon locked box or I guess it is called a smartjack with 2 CPE's. I have to extend to 2nd floor using red/blue blue and red/orange orange pairs of the 25 pair house cable. How would I wire this coming out of the verizon box in the basement? Using a "B" configured biscuit jack and how would I punchdown on the block,in the usual order? Thanks for any help guys

Wire up a jack 568-B. Punch down the White/Blue and White/Orange pairs from the jack to the Red/Blue and Red/Orange pairs on the 25-pair house cable. You won't need the Green or Brown pairs from the jack. Do the same thing at the other end. Use a Cat-5 patch cord to go from the Smartjack to the jack downstairs. Your circuit is now extended upstairs, but without the shorting bars for loopback, so you might want to use a T1 loopback plug to test back to the Smartjack (check for the RLOS light to come on with nothing plugged in, and to go out when the loopback is plugged in.

If the future, it might be best to start a new topic, instead of adding on to a contentious thread from a couple of years ago.

Thank you for your detailed answer Tony, it is much appreciated.
