The relays were from WECO. Made by the millions, they were the ones used in all Bell telephone exchanged from the early 50's up to the ESS (electronic) exchanges. Remember seeing ones with less then a full compliment of contacts, but that was pretty uncommon.

Once you convert from Bell to English things make a bit more sense. One has to have a understanding of analog engineering terms but this oldie pretty much works the same as any Hayes etc modems. The Modulator takes digital 1/0 levels and converts to one of two sine wave frequencies. The Limiter,

I don't but. If there is not a connector on the back, you will need to route the signal to one. Find the erase button and look at the voltages. The "erase" signal will either be grounded to function or will be raise to a voltage level +5 or +12 for example. Once you have that, all you need is a
