Telephony Passed

Bruce and I worked for the same Telephone Company back in the home territory. I left the company after fifteen years to work for a Telephony manufacture. So over the years we have kept in touch. I recently called him to see how he and his wife and their two girls are doing. Everyone is doing great. As we were talking he mentioned that he found a video he had made of several Center Offices and the PBX we had both worked in. This tape is over twenty years old. It was a delight to see all that equipment again because most of it does not exist anymore. Thanks Bruce.

What is this for Dial Tone by 8:00 and 8:13

@Aurich02

The tones are trunk digit tones and he is calling a 1000 cycle tone.

I second the thanks to Bruce.

I never lived in a household served by crossbar; only SxS, #1 ESS, #1A ESS, and in recent years probably DMS-100 and 5ESS, which are no fun at all. I loved playing with a crossbar switch whenever I could, from friends' and relatives' homes. I loved the sounds it made in the phone earpiece. I loved the little "wait; I'm thinking about it" delay after the final digit was dialed, followed by the brief, ascending tom-tom riff as the call was put through.

Thanks rsp196607

sounds like large groups of relay style elevator controllers.

@mathewbailey08

Oh yes, thousands of relays and switches. Lots of maintenance.

[thecooldude9999]

@AllAmericanFiveRadio multi-frequency tones.

[rsp196607]

@AllAmericanFiveRadio Or the sudden LACK OF sound if there was something wrong, I suppose.

I like the sounds of the #5 crossbar switches. I also like the MF tones. I might have had a #5 crossbar switch where I live in Westchester County, New York.
