Quote from: poplar1 on September 14, 2023, 07:14:09 PMIf this is a common battery switchboard (lift the handset or receiver to signal the attendant), then you should not be connecting magneto telephones as extensions, or, at least, not sending ring voltage from the stations (extensions) to the attendant.Magneto phones can only be connected to the trunk (outside line) ports.
Quote from: Ohliuw on September 14, 2023, 10:16:41 PMThanks!!! any explanation why? Also, is it possible to rewire the magneto phones to use them as extensions?
Quote from: tubaman on September 15, 2023, 03:07:08 AMNow I'm confused as I agree that you shouldn't send ringing voltage from a magneto on a CB system but then why would it be ok to have magneto phones on the outside line ports?
Quote from: countryman on September 15, 2023, 07:54:30 AMIt should be possible to use regular dial phones as extensions on this switchboard, just the dials have no function. As poplar1 said the LB (magneto) phones might be rewired to CB, but it's a bit elaborate.12V might work as a supply for the switchboard, but normally at least 24V were used.
Quote from: poplar1 on September 15, 2023, 05:49:52 AMBecause a local battery phone (with magneto), like an incoming trunk (outside line), provides its own talk battery and ringing current to signal the switchboard.
