atcomsystems.ca/forum Forums TDM Business Telephone Systems Avaya - Lucent Telephones & Systems Line protector availability

When our Partner system was installed, the installers, from Lucent, as I remember, put in AT&T 504A1 protectors where each line left a building and where it came back into a different building.

I have used up the stash I had of these things.

What does everybody use now? I can't seem to find them, or their decendants.

The numbers on the front read AT&T 504A1 protector, 106392566, ITW Linx, 708-952-8844.

Any ideas? I have repaired a few of them, soldering in new fuses. But I don't know if that's cost effective.

Steve, aka Trainwire

you have the info, ITW Lynx and the tel number right in front of you. Also chedk the ITW lynx web site.

I use a different brand but you should be able to find a replacement heatcoil from any one (Graybar, Annixter, etc.)

Hey Trainwire, I'm right down the street in Gap, I'll see if I have any of those protectors laying around for ya. I'll stop tossing them and save them when I get any.

doh, ever have a day you shoulda stayed in bed?

I do know that the phone # is no longer valid, or at least the one I tried didn't work. And for some reason ITW Linx never came up on the search till this morning. <sigh> Now I feel dumb.

Of course the ones that match what I have on the wall aren't available anymore, that I can tell anyway.

Thanks guys.

I purchased 25 of the equivalent from Graybar. I gave them the numbers off the ones I had and they crossed them and sent new ones to me.

Graybar knows how to cross-reference things?? You must have a good rep.

Don't know specifically what most of you guys are refering to without part numbers. What you are talking about is what Lucent (aka AT&T, Avaya) calls an IROB-In Range Out of Building protector. I don't remember what the part number is for it, I believe they started back in the Merlin days where they were 4 pair. For the Partner they only need to be 2 pair. Doesn't matter because I never used them.

There were very few times when we only needed to run 2 pair for one extension to another building and that's what these IROBS only handled. You needed a lot of them and they were expensive.

What we use are ITW Linx FPP4-235 5 pin protectors, these will handle 1 pair. They consist of solid state protection (235 volt)and sneak current fuses. We also use them as secondary protection on all CO lines before the system.

You plug them into a "block" that has 110 punch downs in and out and a ground lug. For up to 6 pairs we use an Avaya #110ANA1-06 (from Anixter) and for 25 pair a block from Marconi.

How do those products compare in cost to a Portasystems protector? They are who I use.

From your link, these are what I remember seeing on ATT/Lucent/Avaya stuff (see the following link). I think I even had gotten some by APC back about 6 or 7 years ago.

Porta Systems I think is a bit more. We have been paying $4 for the FPP4's and $51 for the 6 pair block from Anixter. The Marconi 25 pair block I believe is $100.00.

What's nice also is these are standard 5 pin protectors and will plug into anything made to take them. You are not limited to just one manufacturer like you are with Porta Systems and their "pogo stick" protectors.

The ITW protectors that you linked to were originally made by Panamax who recently sold out to ITW Linx. AT&T and Lucent used Panamax as a supplier who provided custom branded products for them without the Panamax name. I was not aware that the relationship continued when Avaya was formed or when Panamax was acquired by ITW Linx.

Also, probably a regional thing but I have never seen Lucent or AT&T provide those protectors you mention. They supplied Panamax power line surge supressors but the CO line protectors were always Porta Systems.
