[ale] OT Looking for telephone connectors.

[Jim Lynch]

Sorry it's not Linux but I know some of you have worked around the 
telephone industry and might be able to help.

Take a look at these two connectors.  http://k4gvo.com/con.html
They are part of a phone system used by a call center.  The first one is 
a 3 wire circuit, headset with mike/ptt/earphone.  The second is just a 
handset.  I would very much like to be able to use the headset plugged 
into the jack that the handset goes to.  I'm hoping the elements are 
compatible but if they aren't I can work around that, but I need to find 
a 2 wire plug, like the ones shown.  I can use a pair of standard 1/4" 
phone plugs, but if the whole plug is available somewhere I'd rather use 
it.  I also need a jack for the 3 wire circuit.  That's the kicker.  I 
haven't been able to find anything like it.  The old Collins radios used 
one similar, but it was a slightly smaller diameter and besides, 
cannibalizing old Collins gear is almost sacrilegious, not to mention 
expensive.

If someone can identify that jack and/or refer me to somewhere I might 
pick those parts up I'd sure appreciate it.  I don't know what to call 
that type of jack so I can't really do a search on it.

Obviously I'd rather have an inexpensive solution, like perhaps a 
surplus/used equipment dealer.

Going to the dealer of the phone system is out of the question for 
economic reasons.

Thanks,
Jim.
