As we know, the AC ringing current supplied on an average POTS line (UK/US) is around 70-90 VAC @ around 17-20Hz. Based on this, I recall that older phones had neon indicator lamps connected across the copper pair (48V tip and ring) - I just recreated this and the single neon lamp FLASHED LIKE CRAZY!
Strangely, it didn't strobe with a "Brrr-brrr.... <pause>.... Brrr-brrr....<pause>" cadence, as per BT landlines, but basically strobed as long as there was any ringing current on the line - I don't currently own a scope capable of handling this voltage. I have 10 of these lamps and I want to parallel them all up together across the line, and knowing they draw a gnat's fart of current, would this affect the "REN" (Ringer Equivalence Number) of a BT landline, do you reckon? In fact, if anything, since they are a type of gas discharge tube, surely they would also aid in surge suppression.
In the 90s I'd not have the net and would wing it and work it out myself, but I'd like to know if anyone has some insight. I know, it's a VERY trivial circuit, but I do not want to interrupt our broadband or landline calls.
PS: Not fussed about BT's ridiculous "BABT" rules - this is a theoretical circuit for now.
Cheers me dears, and if we don't speak again, a very blessed and peaceful Christmas to you all!
