Darrell, The 19D413943G3 is a "Remote Keying Panel Interface, Option 7442" for converting a second receiver in a Mastr Pro 72 station to a voting receiver. The station must first be modified for a 4-wire tone remote control. This unit has nothing to do with telephone interconnect operation in its original application. The manual that covers this unit is LBI-4909. Product Code 72 has some information: <www.repeater-builder.com/ge/product-code-indexes/index-pc72-professional-72 -stations.pdf> or here: <http://tinyurl.com/5cthvd>

Hi all, I have here what I think is a simple telephone interconnect made by GE. The # on the front is PL19D413943G3. This came out of a GE MASTR PRO station, and I wish to use it with a different system. I'm pretty sure that I've correctly figured out the wiring, but I'd like to see if it even really is a phone patch or not. If it helps, its housed inside a 1-3/4" high rackmount case, with just a single circuit board. Any help is very much appreciated, and thank you in advance..... - Darrell/KA7BTV
