Hi all,

I am looking for some equipment for my company. The boss likes to have the 1A2 Phone System in place, but he's tired of daisy-chaining his feed right in front of each phone/fax.

We're looking for a way to localize the splitting and hope to find something that can take 1 amphenol In and turn it into at least 6 amphenol Outs.

Speaking with parts guys, I've heard I may be looking for a Patch Panel that is a 1x6 Amphenol Splitter, perhaps a Break Out Box ...

Bottom line is I want something that uses Amphenol Ins and Outs and creates several Outs.

If anyone can help me limit my search, offer me terminology, part names, parts numbers, or has this kind of part somewhere, please let me know.

My company is called Interpage.net, you can call me at 510-315-2750 or respond to my email through the board.

Any help is much appreciated. Easy on.

What you are looking for is called a bridging adapter. I remember having some that were 1 in and 4 or 5 out but can not find them anymore. The only ones I have seen recently are 1 in with 2 out.

Amphenol makes a KS-19252L1 or a KS 19252-L3. One in and two outs and daisy chain a few together. If your using older western sets such as six buttons you will need to remove your Vl Brn and SL Pairs from the sets. I think it's time to stop watching Black and white TV and get some color on the screen. One other way would be to get an older amphenol cat 3 96 port patch panel and make modular jumpers on the ports. What a mess but it would work. You would have somthing about the size of a plastic milk box when your done. Hey, the plastic milk box will hold your wires nicely.

Ive seen what your talking about on ebay and wondred who would still be using that stuff .

you might want to check out ebay .

Suttle is about the only place you are going to find something like this. I don't know if they actually still make these items, but you might find them on Google or e-bay. Here is a place to start:

Suttle #SE-825L6-1P49 (gray) or 1P50 (beige) has one input and six outputs
Suttle #SE-825L7-1P49 (gray) or 1P60 (beige) gives seven outputs.
Suttle #SE-825L8-1P49 (gray) or 1P60 (beige) gives eight outputs.
Suttle #SE-825L9-1P49 (gray) or 1P60 (beige) gives nine outputs.
SE-825L10- yadda, yadda; 10 outputs
SE-825L11- 11 outputs
SE-825L12- 12 outputs

Remember the thing about disconnecting the violet/green, violet/brown and violet/slate pairs within the phones or you will be in for a world of trouble.

What you really want is the Suttle #899-1A2 which is a 10-station cross-connect system which allows you to change certain features via a single 25 pair connector. If you aren't using intercom, that probably wont' be an issue.

These all are probably long-since discontinued, but you might find someone who has one or two sitting in storage that they want to get rid of.

If you can't find any of these, then you are pretty much out of luck for an off-the-shelf solution. Still, there are probably ways to have a custom assembly made. Let me know if you are in a pinch and I will see what we can do for you.

Thank you everyone!

I am on a much better footing to start finding this stuff. I will be back on, especially if we start building stuff ourselves.

Thanks again.

Forgive me for asking this but what is in the mind of somebody who would want to actually use and maintain a 1A2 today?

I know there are some out there that still exist mainly because they have been there and still work but to put money and effort into them for MACs is ridiculous unless it's just for giggles.

Like somebody said, it's time to throw away your B&W TV, color has been perfected...

your going to start building 1a2 stuff ?
:toothy:

That's great Im going to build 1a2. This is what it stands for.... One sting and two cans. I like the sound quality of the maxwell house type coffee cans and for the sting I use piano wire. Better for long distance calls. 1stringAnd2cans! Number please?

These things were called CPCs or PCPs because you had a little beige or gray box that had three or more amphenol connectors or plugs.

One female cable coming out of the wall would plug into the center male plug and the printed circuit board would give you a female connector on either side to hook up two phones. Thus a CPC.

These were made in all kinds of combinations and for double 25 pair cables and tripple 25 pair cable etc.

A box to give you three 75 pair phones from one cable would be a PPP CCC CCC CCC (plugs and connectors.)

Hope you enjoy the history lesson, it is free.

I see no problem in building 1A2 equipment, hell people are still building chastity belts and the 1A2 is more reliable and more useful.

Hal:

We sold (and continue to service) two national pizza franshise holders, 18 stores total. Both insist upon 1A2 (2564/5 only). The staff was killing any kind of electronic/digital set within a month.

One of them bought 1A2 from us back in the '80s and migrated to electronic key based upon our recommendation and the chain's pressure to buy from AT&T. We were removing it and reinstalling their original equipment within two months.

The other one never let us talk them out of it. Twenty years, and with the exeption of some plastic parts, handset cords and a few dials, almost all of the very same Western Electric sets are still working in their first store.

We refurbish them with a shop vac (to remove the flour), some plastic polish and an occasional replacement part. We keep two phones on the shelf, probably their two that ever failed. We still fix and just rotate them. A helper can go out and replace the set; we just fix them over and over again.

Something to think about. Give (and keep giving) the people what they want. It only fails when it's abused.

One thing about 1a2. There were and probably still are alot of 1a2 systems down around the gulf coast (Galveston Freeport area). The reality was that the old systems were much more robust when standing up to the salty air. Yep, even with all the relays and what not the 1a2 would survive when the electronic systems were dropping like flies. Go figure?

Why do so many people make fun of 1a2? With all the bad experiences I have had with broken keysets, cheap keypads and overpriced components 1a2 is a refeshing change. Also love the choice of bell or buzzer for ringing. The only drawback to 1a2 is the cabling but I am getting better at dealing with it. Western Electric did make a box with one AMP male and six females, I have one hooked up at my parent's house. At my place I just use 66 blocks and wire up female AMPS from there. The way I see it, if you're using touch tone and not rotary there's no problem with 1a2. Personally I prefer rotary dial!

i'dd do it all with split blocks and
3 pair x connects

If there is one thing to be said about 1a2 equipment is that it was built to last and that's because it was owned and rented to the customer by the phone company. The less they had to do with it the better, they just wanted to collect the rent every month. Face it, if the stuff we sell today was as well built and reliable we would be out of business!

I feel so silly, I now rememeber how I tied 5 phones together..I used a SCSI ribbon cable with several connectors crimped on! It works great and is still in service. Let me see if I can find an extra one to send you for just shipping.

Don't feel silly. I once saw whole offices and a shop area that had their 1a2 wired the same way with ribbon cable. It was an electronics company and they wouldn't spend a dime if they didn't have to.
