[comp.dcom.telecom] Box Needed to use Single Line Phone on 1A2

cjp@uunet.uucp (Charles Jay Pilzer) (03/16/91)

I have an old phone system in my home that came from my office.  I
think it is 1A2 equipment.  It has ten button phones with transparent
square buttons and uses A-A1 lines to signal the busy lights.  I want
to use some modern single line phones on the system.  I got a box from
TT Systems Corporation in NJ called a "key system adapter" which has a
sandwich plug in the 50 pair line and buttons with busy leds for the
first five lines.  They don't make it any more.  The new box they have
is a TA-50.  But when I use it it causes the bells on all other
extentions to fail when that line is selected on the box.  The phone
connected to the box rings.  I would like to use these boxes but can
not solve the problem.

I also have a box that was made by Northern Telecom which sort of
matches the phones that also has six lighted square buttons, that I
use to switch a single line phone.  This box does not have a circuit
like the T-10 to make the A-A1 connection, but I have solved that with
a small relay that senses talk current.  The questions I have are what
is this box called and where can I buy some?

Thanks for any reply.
