Old telephone systems.

[KA5PIU]

Hello.

Terrell Plaza shopping center has been bought by Target stores and will soon be torn down and replaced by a super Target so I was invited to come along.
I hit the telephone closets.
In one was an entire AT&T partner plus along with some VoIP ATA units as well as the usual 1a2 and executone stuff.
A pair of bogen intercom amplifiers and talephone paging interface also came home.
In the other telephone closet was the neat stuff, an entire digium asterisk cage, fully populated and with power supply, no computer.
Another pair of paging amps and an SCA receiver.
I now have well over a dozen ATAs but do not know yet if they are locked to any one carrier or not, my guess is yes.
And there are a few more phone closets to go!
Keep a lookout for this type of thing, this may all turn out to be junk but at least it is worth a try.

Sounds like a goldmine of stuff, esp if you're into phones.

When it comes to phones I'm into the old stuff. I want an old candlestick phone. I also like 1940's - 50's style black rotary phones and those vacuum tube telephone amps that were hidden in crevices in basements, closets, behind furnishings, etc.

Just a few blocks away from me. I've told the family that if the place ever catches fire, drop everything and get about 30 miles upwind. 4 levels packed from front to back, side to side, floor to ceiling with phone crap from the beginning of time. If they don't have it, it wasn't made.

You must have a lot more storage room at your QTH than I have at mine, Rudy.

Always room for plenty of air.

The Partner Plus systems are older, and firmware updates have stopped (Avaya has stopped with the Partner systems support), however, they will last a good long time.

The Bogen equipment is really good stuff. Again, should last a good long time, and can most likely be refurbed/cleaned/sold to a customer.

Asterix cage is probably useless, as Digium isn't going that route anymore, and parts are like hen's teeth. The ATA's can be put to use for a home PBX.

Hello.

Tend to agree but this is old stuff
Got the partner plus to power up and connected 2 stations, it works to the level that I understand.
The bogen equipment does not work, or at least I have yet to have success.
And, yes, the Asterisk cage is most likely useless.
The VoIP adaptors, it depends on if they are locked to a carrier or not.

What modules do you have?

The bogen equipment does not work, or at least I have yet to have success.

It's a grounded system, so you need shielded wire to get it to work (Three terminals: Signal, Ground, Shield). And, it's 70V. Enough to knock a person off a ladder (I know from experience).

And, yes, the Asterisk cage is most likely useless.
The VoIP adaptors, it depends on if they are locked to a carrier or not.

Most likely, they aren't. If they are, possible they can be unlocked.

Hello.

This has 3 of the 206 modules, one processor module and one something else.

Hello.

The 2 bogen amps are tubeless, as in no tubes in the sockets.
The other pair are transistor and the transistors in the output section are missing.
I looked at the schematic, plopped in a pair of 2n3055 and set bias, good.
I am going to put in a pair of 2n3771s in the other one, and replace all the caps in both.
The pair of tube amplifiers may not be worth the effort.
Got the Partner Plus programmed and working to 100%, not bad for an analog system.
The SCA units? SCA is obsolete around here so it is just an FM tuner under crystal control.
There is all sorts of 1a2 equipment here, everything but the sets themselves.
