AC14 (2280Hz) Signalling Demo Progress…
The wiring between the relaysets is done with the exception of the connections that go to the #phone end, the #phoneExchange end, and the 4-wire circuit between the two ends of the link.
So, 9 wires remaining then I can start powering it up… but first, I need to find a suitable method of terminating those connections that allows me to add in annamplifier/speaker so you can hear the tones.
It’s back to the sketchbook and eBay searches!
