Question for the BIX crowd. How to you isolate pairs for troubleshooting without bridging clips?

In all my years in this industry, I've never seen a bridging clip up here, although I know what they.

To answer your question, simply pull the jumper.

With the mention of bridging clips, I have to wonder: Do Canadian standards include an equivalent to the US' RJ21X jack for the demarcation and identification of CO lines or circuits? Is there a Bix version of it?

Showing my ignorance, I guess, but Ive been in the business 43 years worked all over and dont ever remember terminating anything on a Bix.Im 71 so Im not gonna invest in a blade now.Id have to be retrained and everything.

A lot of bix questions answered here: Belden BIX catalog
I had the bridging clips on one of my installations several years ago. What was then BCTel put them between their rails and mine.

I learned something new; never saw BIX bridging clips before.

I have a few sites with existing BIX terminations, we cross-connect onto 66 blocks for the phone system. Every pair gets bridging clips.

Yes, I have a BIX tool. It's just not what we use.

Yes Ed we use both the Bix demark and the RJ21 We did when I worked here and I don't think it has changed. Here is a picture of the Bix demark. We had a clip that joined the pair.

Too many components for my taste to have to stock in order to do an installation properly.

....And off come the gloves!

All you usually need, Ed is the following:

a) Mount QMBIX10A (Backboard)(Good for 10 Blocks for a total of 250 Pair)
b) QCBIX1A Blocks (25 Pair)
c) Optional QCBIX1A4 Blocks marked off for 4 pair wiring. Optional only if you want it.
d) Label Strips

Not a heck of a lot more than you use....

To answer a question above about DMarcs. Bell will either terminate the lines on biscuit jacks or ON BIX Blocks. Up to me if I'm there.

If however I want to use "jack strips" for the DMarcs, I can use QCBIX36B Blocks (12 x 2 pair modular jacks).

For smaller installations, I'll use the the bottom 2 or 4 positions for the Data Terminations using NXXCBMC6U blocks (6 x modular Cat 6 Jacks.)

This keeps everything neat & clean.

P.S.: I always put the data jacks on the bottom so any patch cords are not dangling in front of my telephone connections.

I see your point, Dave. I guess that for a typical installation that I would do, I'd spend a comparable amount for the appropriate backboards and blocks. The problem is in situations where only a single block is needed. I can (reluctantly) purchase an 89B bracket for about two bucks and a 50 pair 66M1-50 block for another seven. For nine bucks, I have space for the termination of any variety of 25 or 4-pair cables for a small installation.

How do you justify the cost for the hardware when doing something comparable with BIX? I can't see purchasing a full mount for just one or two 1As. Besides, I'd be all kinds of pissed if someone came along and stole space on my BIX mount.
