I have a project to do for a commercial business, which is basically installing a DMARC extension from the 66 block to a jack, and running a patch cable to a DSL router.

The problem is obviously on Qwest to fix, but I thought that I could at least get some insight to how this works so that I can fix it in the future if I need to.


Qwest came in and connected the DSL line to an existing CO line in this facility. The existing line supports a dataline which is used for an external 56K modem, which from there is daisey chained to a phone jack.

The 66 block is a mess. From the pins that the installed the DSL on the 66 block, they then daisey chained that to another pin on the 66 block, and from there daisey chained it onto another part of the block. So off 1 CO, there are 3 terminations on the block, and 2 jacks off just 1 of the terminations.

I tried to tone out the other points of connection for the other pins, but I couldn't find anywhere that they were connected.

So does anyone have any advice on how to clean this mess up? Besides calling Qwest and having them fix their mess...

It seems like this should have been terminated on its own pin, with a dry pin on the connecting side of it.

Anyway. Im just frustrated, and Qwest pisses me off. Maybe this is just a rant.

I would install DSL filter After CO in, and before going to jacks and phones. And use unused pair for DSL to where you need. I Like Quickport, you can have RJ 45 for network,
RJ 11 for phones, I use Brown for DSL. Can be any color.

Sorry I didn't answer better first time, You should have 2 wire in from CO
4 wires out, 2 for phone(voice) and 2 for DSL(Data). You should be able to tone out from there, and with ANI, you know you are on correct line.

I never knew why the big companies went through unnecessary "66" blocks.
I thought they got paid by the block.
I like the new? "66" blocks that have 12 RJ11 jacks or 6 RJ45 jacks on side. Bridge clips make it easily to isolate.
