atcomsystems.ca/forum Forums Other TDM Phone Systems 1A2 and Comkey Telephones & Systems Beginning my 1A2 Project

I am beginning my 1A2 install using an ITT 601 KSU equipped with 5 lines using 400E KTUs and a combined intercom.

I'm laying out the 66 blocks and mushrooms and would welcome advice on properly mounting everything. My plan is to run 25 pair from the KSU to a 66B block which is next to the KSU. I will cross connect from there to the adjoining 66M blocks.

At the top right of this picture is a Cat5 block so I can bring in two C*Net lines from my cable modem/router and a connection to Xlink which supports bluetooth to my cell.

I was planning to use the biscuits below the 66B to connect the CO lines into either the KSU or 66B.

Thanks for taking the time to look. I have greatly enjoyed looking through the archives.

I have a ground wire ready to go as well.

I would offer up using colored backboards as well as backboards for the mushrooms. I realize that ILECS didn't really use backboards, but, there is something satisfying about a neatly cabled backboard.

Red for keysystem cables.
Blue for station cables.
White for mushrooms.

I posted some pictures of my Church's installation on my website.

Thanks Paul! Wow, your church install looks fantastic. The colors certainly make the whole thing look better then a plain white piece of plywood!

I searched for other backboard colors, but only found blue. I did find a source for mushrooms on a white board. Where did you find red?

Paul, thanks so much for the kudos on your site. I don't know how I missed that before. I'm glad that you are one of the few who takes pride in doing it the right way.

Thank you for the complement

Ed Vaughn provided me with some really nice Western Electric vintage purple 1/2 field backboards, Suttle jacks & 66 blocks. One of the backboards is used in the Church install and the other is safely tucked away.

There is a company that lists quite a bit of telecom hardware on his site. Ed tipped me off to the outfit, but, when I spoke with the owner, he sells strictly wholesale, and, wouldn't sell to me...which I understand and have no hard feelings.

I did find a listing for a retailer that lists metal 66 block backboards.

This is a link to the 1/2 field backboards. The site shows 1/4 and full field versions as well.

With the decline of traditional telephone service, color coding isn't observed as closely as it was in the past. Most of the time, a blue backboard is mounted and 66 blocks...if used...are left uncovered...or...a clear snap-on or orange swing cover are used.

The matching swing covers and bridging clips are Siemon brand and were ordered from Graybar.

Thanks Ed!

Well...1 guess who planted that "bug" in my head a few years ago.

Excellent. Thank you!

I've been known to set up a company just because I never buy retail if I can help it or I can't get what I want any other place. My tax ID has my name on it so I can call a company anything I want since they only look to see that you have a tax ID- if they want anything at all. Go to Vista print and have some cards printed up for a few bucks. House is going to need a new paint job, hmmm, where's my painting contractor card.

Just remember the plywood is supposed to be fire rated painted with fire rated paint. Although I don't remember the last time I actually saw it done.

Hal, is this your card?
