Jan 2025: FYI PeriscopeFilm channel just released this old film on step-by-step: ua-cam.com/video/wSylaHLIzYE/v-deo.html

5:50 imagine hearing this while trying to call 911 at night

I was wondering. If you had call forwarding on your home phone on a 1ESS. And you forwarded your phone to another number. Can you still make calls on your line even if the incoming calls are forwarded to another number

Just gotta say the "Chicken Delight Remix" is a real banger as the kids say today. I'm sure Jerry Reed would even dig it.

Sounds of my childhood. Strangely comforting.

13:45 - how did they get Frank Zappa to read the intercept tape??

For an hour every day this was the soundtrack to my dad's work on his bench and from the bank of 5-6 TVs he repaired on the back wall of his shop at Sears that were "cooking" to ensure his fixes took. Thanks for reminding me of that association.

And somehow in the middle of it all, the phone got knocked off the hook, and twenty seconds later I heard a familiar voice. And you know what it said? I'll tell you what it said! It said, "If you'd like to make a call, please hang up and try again. If you need help, hang up and then dial your operator."

Wow a new Evan Doorbell video

In 1986 I had two lines of ComStar II in Van Nuys, California out of a 1A office. At that point in time, the official name of call transfer “out of Centrex incoming to out of centrex outgoing and release”was DID-DOD. Pacific Telephone would not allow incoming non-Centrex calls to be transferred to outgoing non-Centrex calls. Provisioning of DID-DOD was not permitted with the small Centrex product for residences and small business. BTW! I have been and continue to be a huge fan of Evan’s network sounds for the past several decades. I am an old school phone freak. I grew up with GTE SXS switching in West LA and had the fortune of being able to “click the directors (the only intelligent part of step-by-step in your own central office, also the billing logic) off line” to go crazy with the raw trunks to most other central offices in the area code of 213. I could really Dive deep into the network with the unsophisticated Automatic Electric step-by-step offices.

Long distance might not have been great, but local was much better quality than what we hear today. Yes on modern calls, the quality is good, but in the past we had true full-duplex and low latency. Even on the best HD quality cell phone call, you still have more latency and can't really talk at the same time. Add in Bluetooth headset and you're adding even more delay. On the old POTS, you could literally talk and listen at the same time and both of you would hear each other. But over VOIP or just cellular, you essentially have to take turns talking. You're probably thinking, well that's how conversation should go anyway, but it isn't. Being able to interrupt when someone says something silly, or absurd, or funny, etc. is incredibly useful.

Besides Bill and Joybubbles, were there a lot of phone phreaks who worked for the phone company?

About 12 minutes into this video. You mentioned that the call goes to TSP. And you hear the MF tones as the operator is keying the numbers. When I used to have TSPS operators dial numbers. You only heard the MF tones after the operator was done keying the number.

I remember that crazy sound if you layed the receiver off the phone after a couple of minutes it would come on.

We used to get on the busy signal to get girl's numbers and call them, we called it the beep line here in Anniston, Alabama, late 1960s and 1970s, fun times.

Did the exact same thing with a Heathkit GR-64 my dad built in 1969 I would tune that thing up and down the band all night long, would listen to all kinds of things. Was amazing to hear DX AM radio , SSB, CW, foreign stations, BBC, WWV, My brother and I are Amateur Radio Operators, no doubt that Heathkit was a huge influence. After listening as late as my mother would allow it was bedtime. That’s when I would climb in the top bunk and pull out the AA penlight and read Encyclopedia Brown until my eyelids would give out.

Great listening to this. Those were the days. Would like to thank Doorbell for the great entertainment.

4:24 I've tried my best to transcribe the Canadian French here. "Désolé (not quite sure here,) n'y il (a) aucun service, n'y pour le numéro que vous avez composé."

This was the first phone trip tape I heard a very long time ago. I don't remember when this was produced, but I know I was a kid. I'm 32 now, and this is the recording that started my lifelong obsession with NX1s, and electromechanical switching equipment in general. The off-frequency dial tone always stuck out to me. Never get tired of it.

Interesting, I've never heard it called the "vacant level" tone. Apparently it also has variations in pitch and patterns? I've only ever heard two, both low pitched and the same sine wave up/down pattern (as well as the one in your vintage sounds video/programme.) I've also heard the nickname "crybaby" in some instances. This tone also seems a bit elusive, there's not an awful lot of info available about it.

...battery cutoff?

In those connections, it's almost like you can "hear" the city you're dialing.

8:17 This is the "no such number" error siren, right? I heard versions of this at lower pitches, but nothing this high. I wonder if this is something different entirely or a variation of that tone? If anyone else is seeing this: The "no such number" error siren, as the name implies, means that the caller dialed a number that can't possibly be assigned normally. Because such numbers could be for private use, this siren effectively stops the call before it goes through. It's also exclusive to North America.

Hi Evan, no calls to 1101 (iirc) milliwatts or Test Boards?

Operator may I help you

Time to make a telemarketer trap which is just John Davis on loop with random pauses in between

If you'd like to make a call, please hang up and try again. If you need help, hang up and then dial your operator. If you'd like to make a call, please hang up and try again. If you need help, hang up and then dial your operator. IN AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAALBUQUERQUE

sound like a 1-900 number with all those lines connected and cross talk

Was the SAIS operator a TSPS operator or a cord board operator. And what did SAIS stand for?

8:59 - I wonder if that interval tune was based on a hymn? Its melodic/harmonic structure makes me think of a hymn’s structure and I can imagine it being played on an organ with the congregation singing the melody.

It is delightful to hear your recordings from Minnesota, particularly Crookston - very close to my home town 💖

IN ALLLLLBEQUERQUE!!!

HOLD on? were you engaging in espionage is that how you got all this. Speak! who did you work for USA, East Germany?

Only a true American knows Jenny's number

Hearing a lineman on the line trying to actively shut down a conference is wild. What a unique experience!

They were usually carrier telephony. And occasionally you’d end up on a channel where the carrier frequency of the channel card was slightly off and it sounded like listening to an amateur radio sideband conversation that wasn’t quite tuned in properly.

✅ Hi Evan, did you ever make a smartphone ring tone of the Tandem tones pulsing out? It would be a nifty notification sound… I can’t tell how much pleasure all your recordings are. It’s like being in or seeing a DC3 airplane which btw you can play the deep bass with the speaker on a wood table (like a piano sound board) and it literally comes alive. Best always buddy.

Back in the mid 1970's I sent a letter to the NBS asking for an autograph picture of the guy giving the time announcement. I got a letter back from the Chief Engineer of WWV saying the voice announcement is produced by a company in Atlanta, GA.

I found your video randomly, but maybe you can help me. Back around 2000 I used to work for a call center. Normally we took inbound calls, but once in a while we were asked to make outbound calls to call people back, and once in a blue moon one of the numbers we'd get to call back would have a wrong number written down because instead of going to a working line (or a busy one) they'd just sort of hang. You could hear the very quiet static/hum of a normal line, but there'd also be a very quiet whirring sound, and once every few seconds you'd hear one click. This would repeat as long as you'd let it. The thing is, I've always had a SUPER hard time falling asleep, but there was something hypnotic about these dead end lines at made me want to just stay on the line, listen to the noise, and fall asleep. Part of it was that the clicks that happened every few seconds ... they weren't random, they were definitely happening at a specific interval, but I could never figure out what the pattern was. It was almost arrhythmic. Just one click, a long pause, another click, another long pause, etc. I'd always wished there was some way to bring in a tape recorder into my job to record this, but at that time there was no cheap/easy way to record from the headsets we used, so I never got to. If you have any idea what I'm talking about, or have any recordings of this kind of thing, I'd love to get my hands on them. I wonder if they'd still make me want to sleep. I listened through your whole video, and the closest similar thing I could find happens at 27:04. That was the click noise I'd hear, but in your video there's a high-pitched whine happening in the background before and after that click that didn't happen on the lines I'm thinking of. Have any idea what I'm talking about?

It's somewhat amusing hearing 'your mother wears combat boots' in a non-joke context. But boy this stuff is really great.

Jane sounds genuinely enthused with hearing she had fans. You made her day and in turn, made ours

How old is Doorbell nowadays?

Wow! Using the outgoing line of an answering machine to get free message unit calls 🤔, when I found one of these back in the 80s we didn't have a concern for message units, however, we were able to make "courtesy calls". (To no extreme)

I am always interested in new Long Distance tapes! I wish I could hear stuff like this on my 5ESS line!

25 cents in the 1970s? In NYC it was 10 cents until the mid 1980s

18:43 What is the name of the woman reading " This is the final edition of your New York Telephone"..? I understood Helen Banks? Who is she? I LOVE her accent..

14:20... Hello, is this food stamps..? 😆
