Title: Request for Payphone Project Help (Ph.D Student)
Post by: Payphone_Guy on April 24, 2016, 11:55:57 PM
Hello Everyone,

I'm new on the forums and I'm hoping some people might be able to help me.

I'm a Ph.D history student currently completing a material culture study on the payphone.  I have found a wealth of fantastic information through the Internet, message forums, and various sources, however I have two questions I am very much hoping people can help answer.  Help with the first I fear is unlikely, however the second I hope will be more accessible!

First, does anyone know anything about the payphone that was situated at 6377 Quarry Road, Spring Valley, CA, 91977?  This location is a large parking lot known primarily for hosting the weekly "Spring Valley Swap Meet."  I have managed to obtain some information from local newspapers, and I have posted on the Facebook pages for the event asking for any stories or recollections of the phone.  However, perhaps unsurprisingly, I have not received any replies.  Any information on the payphone or the event would be hugely appreciated, however small it might seem!

Second, would anyone be willing to contribute some general stories about payphone use?  I am looking to engage with as many oral histories as I can, and I am searching for any information regarding the industry, or personal stories of using payphones.  If anyone would be interested in providing such information, I would be hugely grateful.  I am of course very happy to discuss these stories on the forum, via email, phone, or via Skype/Google Hangout if this would be preferred.  Anyone who would wish to contribute would obviously receive full credit and acknowledgement (unless they wish to remain anonymous of course).

Thank you very much for any help at all, I hugely appreciate it. :)

Welcome!
I suppose you have visited the place already, haven't you?
Just like in archeology, visiting the place might be a good continuation after education.
What is this structure by the road side?  It seems to be a likely candidate for the location.  Is it supposed to be on the south side of the road?
There are parking lots everywhere around.  Wondering, who needed so much parking space? There are no large buildings there anymore.

Next I would to try to narrow down the telephone numbering plan for the area.

The numbering plan area (NPA) history of southern California is as follows:


1947   1950  1951   1957  1959   1982  1984    1991  1997 1998 1999  2004   [overlays]

                                                     760___________________2009:[760,442]_



This shows that the entire southern part of California was assigned area code 213 in 1947.  In 1951, area code 714 was split off and from that 619 was split in 1982.  Today, Spring Valley is still located in area 619, although 760 and 858 were split off in 1997 and 1999.

So, now you need to asked yourself which time frame this pay phone may have been at that location and the answer tells you the area code that the phone would have used, either 213, 714, or 619.

Next you can research the central offices that could possibly have been the wire center for this telephone.  My guess is there are only a few candidates, either in La Mesa or another eastern outskirt of San Diego.  This will provide you possibilities to determine the central office code, i.e. the next 3 digits of the 10-digit telephone number.  You probably want to consider only central office prefixes that are still in control of the incumbent local exchange carrier, e.g. Pac Bell.

From data bases, such as www.telcodata.us, you can find central offices.
The few that pop up as primary candidates are those in National City (to the west), La Mesa (to the north), and perhaps in Chula Vista (south).

Here is a map, but I didn't extend it far enough to include Chula Vista.
La Mesa is about 4.5 miles north, and the National City rate center is even closer to the west.

National City: 2228 Saipan Dr, San Diego, CA
Building code: SNDGCA05
Prefixes:  267 470 472 475 479 731

La Mesa: 4711 Spring St, La Mesa, CA
Building code: LAMSCA01
Prefixes: 337 460 461 462 463 464 465 466 469 589 644 667 668 697 698 740


There is another very valuable tool, the Telephone Exchange Name Project which lists the old central office names from the time when telephone numbers consisted of letters and digits (up to the 1960s).

Searching for Spring Valley, I found this entry by Hugh Hamilton:

47   GR   GReenfield   Spring Valley   CA   USA   Personal knowledge   Hugh Hamilton <hamilton

This tells us that the central office (exchange) name was Greenfield, and telephone numbers would be written as GReenfield X-XXXX, and  dialed as  47X-XXXX.  GR stands for the digits 47.

Comparing this with our exchange list above, we have a match on the National City rate center:

470, 472, 475, and 479

These prefixes are owned by Pacific Bell, which is indeed an incumbent local exchange carrier (ILEC).
So, with some degree of likelihood,   SNDGCA05 is indeed our central office building of interest, responsible for any pay phones in that area.

Now, you could simply look up the telephone number for that central office and explain your project. [hmm, not sure whether that can indeed be obtained... more research...] Perhaps they can help you locate that pay phone and perhaps even the telephone number.

Here is a picture of that central office.  Looks like someone is parking in the lot, so perhaps someone might indeed be there to answer a telephone call, of course if you are close, you could just make it a field trip, but it doesn't look terribly inviting, I don't see any door bells.


We have some of the best pay phone history experts on this forum, I am sure you will locate them shortly with a bit of searching.
I am sure many here would be interested in your pay phone research, and I am sure it would stimulate many good discussions.

Some small business establishment just down the road has the telephone 475-1005 at 6301 Quarry Rd.
The self storage place has a number in the 479 prefix, 479-1977.

So that should be good enough to confirm the central office assignment.


So, what is so special about that pay phone ?

I would try to call that number 475-1005 and ask if any one knows anything about that pay phone.  Seems like that shack has been there long enough.

PS:
the number belongs to:
Ervin Rubey
Sweetwater Auto Wrecking
6301 Quarry Rd
Spring Valley, CA 91977
Phone: 619-475-1005


I have also found addresses with the  267 prefix on Quarry Rd, but it is the same CO.

You're enjoying the hunt, aren't you Unbeldi? ;D

Welcome to the forum, Payphone Guy! As Unbeldi said, it all depends on timeframe. If it were installed in the '80s or '90s, it was most likely a 1D or 1C-style touch-tone single slot phone (probably the most likely guess). If it were installed in the late '40s to mid '60s, it would probably be either a Western Electric 3 slot or an Automatic Electric 3 slot payphone.

The difference between being manufactured by Automatic Electric or Western Electric mostly depends on the telephone company each manufacturer had contracts with; AE built most of their phones for General Telephone Co (GTE), and WE built most of theirs for Bell System, a much larger company who probably had territory in that region (each company had their own territories, and didn't share service, or overlap, in any areas of the US, unlike cell service today).

Chances are, if it was around by the '90s or so, it's very likely a single slot payphone, similar to the 1st picture attached. The 2nd picture shows a basic 3-slot payphone design (WE) that could have been built anytime between 1945 or so until about 1975, and 3-slot service was gone by the late '70s; someone help me if that's incorrect.

Do you have a picture of it? That would really help us out in determining which type it is, when the picture was taken, etc. I'll let the real payphone guys help you out in the technical department! ;)

Wow!  Just Wow!

I'm not quite sure what to say other than a huge thank you to everybody for such great help (and humor!).  I apologize for the delay in replying (I'm finishing all sorts of essays right now, so my work schedule is rather, well, chaotic).

The information here is fantastic and I'm going to try and contact the central office tomorrow.

In answer to the other queries...

I'm interested in that payphone, simply because I actually have it!  I was able to purchase it for relatively little money and part of my coursework is to write its history.  I have attached an image of the phone which I hope is helpful!  From other documentation I've looked at I believe the phone is Western Electric 1D2 model.  I know the location as it is printed on the phone itself (which one of the reasons I decided to purchase that particular phone).

In terms of my examination of the phone itself, I am trying to understand how the payphone (which, at this stage in the project I am essentially using as a broad representation for other payphones), functions within four networks of experience:

• Ergonomic exchange (how people physically interacted with the phone and what this means)
• Socio-cultural exchange (how the phone has influenced the behavior across the variety of its users, and how the phone has been appropriated as a social and cultural node by those users)
• Capital exchange (how the phone works a node of capital exchange including payment, protection of funds, collection of funds, etc.)
• Spatial exchange (how the phone might collapse notions of space and time in unique ways such as altering the notions of private and public space)

Such analysis is of course a long-term project, and at this stage I am starting with the basic factors of payphone operations, identifying who the users might have been, and the environmental factors of its existence.

In light of this any information (obviously including that above) is hugely appreciated.  I've been able to obtain sales cards, operations manuals, and various internal company documents from online archives which people have so thoughtfully assembled, and I have gleaned a lot from the Payphone Project and similar sites, but getting to the real exact details is always hard!  I've also done some analyses on local newspaper stories relating to the Spring Valley Swap Meet, and used historical census data to estimate use of various demographics.  Once I've pulled this altogether into some more coherent assessment, I'd be very happy to share it if people wish me to do so!!

Thank you so much again to everyone!

Welcome to the forum:

Other than how did I use the phone, I am afraid I don't much understand the other three bullet points, but let me try to answer if I can.

Interaction:  Pay phones used to be everywhere.  I don't think many people gave them much though unless they didn't work or if there was a waiting line.  I would say that the experience was about as fulfilling as when I currently use the office vending machine to buy a candy bar or soda.  Ergonimically, they were  cramped and for all but the real older ones you had to stand and use the phone.  In my earlier life, you did not see a pay phone that was friendly to disabled people.  Often times they were so noisy that you could not hear the other person if you were on a busy street somewhere.  It also wasn't until later models that they used amplified handsets.

Socio Cultural.  I am afraid I don't know what you mean by "how the phone has been appropriated as a social and cultural node by those users"  What I do know is that the payphone made it possible for people "on the go" to remain in contact with the world and to have access to the phone system usually wherever and whenever they wanted.

Capital exchange?  Unless I am totally misuderstanding what you are asking, the pay phone was set up to collect money for the call, and the coins collected were held in a vault in the base of the phone and then a person would physically go out to the phone and collect the money and take it back to the phone company periodically.  There were many security measures built into that activity.  Phones were built like tanks because people would try to break into them and steal the money.  Repairmen (yes "men") who serviced the phone itself only had access to the upper housing and had no access to the vault.  Those who had access to the vault were under much scrutiny and dual control.  There has been much written on the security aspects of pay phones.  There were also measures built into the way the phone initiated a call in order to keep people from getting free calls.  When I was probably 12, someone told me how to take the cover off the subset of a payphone that was usually screwed to the under side of the shelf that held the directory.  Once the cover was off, a 1,000 ohm resistor from the tip side of the line to ground would give dial tone and a free phone call.   I successfully did this often from one particular phone that was in the parking lot of a shopping center along my paper route.   It seemed that many people knew how to do that, but the phone company let that "freebie" go on for a long time before they did something about it.  At least where I lived.  It probably cost them more to solve the problem than the problem was costing them at the time.  They were probably busier trying to catch the Captain Crunch guys.  (Another topic).

Spatial Exchange - I don't recall any collapse of space and time.  I do know they were cramped.

There was a certain level of seediness and desperation associated with using a payphone.  People with no fixed address, or who conducted business on the street (drug dealers, prostitutes), or didn't want their call traced (bomb threats, anonymous tips, etc) and people who were stranded and needed a ride would use pay phones.  In order to use a payphone you needed to have change, in order to sustain a conversation longer than a few minutes you needed more change.  It wasn't like today when people just casually call or text one another without a second thought.  You used a payphone out of necessity, not for fun.  In order to use a payphone you needed to have change, in order to sustain a conversation longer than a few minutes you needed more change. There is another reason payphone were armored other than to protect the cash: desperate people would take out their frustrations on the phone in the form of violence. 

You would always check the change return, however, because you might find a dime.

Just to clarify, many places did not require additional coins to be deposited for "overtime" for local calls, regardless of the length of call. This would include many cities (Atlanta, for example) and all areas wirh Western Electric CDOs (Community Dial Offices).

Yes, they were. And they were also used for legit commerce.

Having had the privilege to be in sales and having to cover first the nation by flying and then 5 wholes states by driving, all in the 80s and early 90s, payphones were essential to commerce. I remember the 80s and being at major trade shows or conventions halls or hotels with conference rooms and at each break, the room would run to a bank of phones, a large room with 10 to 20 payphones lining the wall, to call the office for messages, a customer or a lead for an appointment. Would have to wait in lines 3 or 4 deep to make a call.

Then, while traveling, a payphone at a gas station just off of a major interstate was the only link to call the the office for messages, a customer or a lead for an appointment. Pull up next to it, roll down the window, grab the receiver, dial the number and roll the window back up to cut out the road noise, and on some days the rain or snow.

And airports would have multiple payphones in one area for the same reasons but without the waiting lines and many of these had seats. Making a connection from one flight to another always included a stop at a payphone to check in or make appointments.

It wasn't until about 1991 that cell phones came into being, the floor mounted car types which came with very costly roaming charges when out of home area. Initially so costly that pay phones along the road were till the first choice to do business. I got my first Motorola flip phone with extra batteries in about 1993 or '94. From that point on, it seemed, in retrospect, to be downhill for the payphone.

Highway and hotel payphones were rotary and required a small handheld DTMF device to get into ones tape driven answering machine for those messages. Eventually, they converted over to touch tone payphones.

That's about all I remember from my days of being a road warrior, except, yes, you would always check the change return because you might find a dime, or more. Call doesn't go through, the caller rushed off, and whatever was deposited for a long distance call was returned, and sat there waiting for the first coin return checker to hit the jackpot.

In some places, Touch-Tone payphones were converted back to rotary, in an attempt to prevent drug dealers and others from being able to call pagers. Or, at least those dealers not smart enough to have a pocket DTMF dialer.

Other places, such as Québec (City), restricted the lines to outgoing calls only. Other than semi-public phones (where they were installed inside businesses, and listed as the business number in the directory), I never understood why most pay phones were equipped for incoming calls, since, other than the rare "collect to coin" calls, incoming calls provided no revenue.

Post by: unbeldi on April 27, 2016, 10:48:09 AM
Ok,  you're most welcome.

I think, the key to the reason for that pay phone location appears to be the original use of that parking lot.
Quarry Road is relatively short, a connector between other, more major roads in the area.  The name suggests that the road may have served as access to sand pits.   What else, other than sand, could be found there in the desert? :)  The only reasonable location for such pits would be the location of those parking lots on both the north and south side of the road.

Continuing the speculation... When the pits were no longer needed they may have been filled in, and the terrain leveled.  As San Diego expanded farther and farther out into the desert eastward, This may have become a valuable location at the intersection of two major road ways.  Perhaps there was a small mall on the triangular plot on the west side of the parking lot, that is now a barren tract?  Pac Bell must have had an incentive to place a pay phone, a place where many people would go and likely where they could park.  I doubt they would have placed a coin station at the private parking lot of a corporation, most people who would park there, would likely rather use a more convenient phone in the offices, or a private pay phone in the lobby.

Given the type of coin collector that you found, it is likely that it was installed from the late 70s or early 1980s onward.  I am not sure of the exact introduction of the D series of pay phones.  The 1D1 was the rotary version, and 1D2 touch-tone.  The 2D1 and 2D2 were the corresponding panel types, rather than the box form.

I suspect that the central office switching system was probably either a No. 5 Crossbar, or a No. 1AESS system, although by ca. 1974 AT&T did not list an 1AESS installation there.  Today it is a No. 5ESS system. These became available in 1982; the roll-out of these systems was very slow, leaving the market open for competitors, especially to Northern Telecom, and indeed another central office in National City (NTCYCA11) at 716 Highland Ave, still has a DMS-100 system installed today, serving the prefixes 292, 336, 474, and 477.

Based on these dates, it may be that this pay phone was only ever in service in the 619 area code, but perhaps there was an earlier type at that location. Perhaps it was upgraded when the central office switch was upgraded. Pay phone types have some prerequisites in terms of equipment needed at the central office.

Studying the urban development of the region would be useful to figure out what happened at this location.

Does the phone not have a label for its telephone number?  Public phones were indeed used not only to call out from that location, but often people would wait there at an agreed-upon time to receive a phone call. I don't know whether this was possible at all pay phone installations.

Some databases exist that list the installation date of central office prefixes, I used to have access to one some years ago, most free services now only list these dates starting with ca. year 2000.   I think, even the official NANPA website only lists the more recent ones, but I may not have looked into that enough.

I found this listing:   https://www.reversephonenumberlookup.me/phone/619-475-1005/
It states that the NXX prefix 475 was installed on 1994-02-04.  When playing with that site, it turns out that it also lists all the other 47X prefixes as being installed at that time, as well as 267.  The prefixes of the DMS-100 system in National City were also installed on 1994-02-04, if that site can be trusted in terms of accuracy.

From the TENP database we do know that 47X was available already in the 1950/60s in Spring Valley, so perhaps these dates can't be trusted that much, who knows when these databases were created and under what circumstances.

During my little excursions into the desert :-) I learned a bit about local history (http://springvalleyca.com/history.html) as well, and it seems to relate to telephone history in one aspect.

The area was well known already in the 18th century by the local natives and the Spanish for its natural spring of fresh water, known as St. George's spring (transcribed),
In the 1800s it was settled and someone owned much of the area as a ranch. It was sold to the family of the founder of the magazine Scientific American and  named Spring Valley, although it was still known for some time as Helix, including the post office.  The ranch became one of the largest olive ranches in S.Cal.

It appears, the spring gave rise to the little lake south of the area, Sweetwater Reservoir, the name of which can be found in many places there, including the little automobile wrecking business next to the parking lot, as mentioned in an earlier post.

The spring can still be seen in arial maps in Google Earth, it is clearly highlighted by a line of trees along its bed, actually appearing to flow right south of our famous parking lot.

And this spring may also be the reason for the name of the central office and exchange, Greenfield. Surely the water may have been beneficial for anything living and green in the immediate vicinity.  GReenfield is one of the officially sanctioned central office names promulgated by AT&T in 1955 (Notes on Nationwide Dialing).  This does not mean the central office was renamed at that time, it could well have been in place before, and it would be interesting to find some newspaper articles, classified ads. or an old telephone book of Dan Diego, dated prior to 1955.

Turns out I have a personal experience from Spring Valley.  A long time ago, I was on a business trip to San Diego, and my host lived in Spring Valley. On the weekend he insisted to take me boating in the Bay. We drove out to his house in Spring Valley, it was hot and dry, it really felt like the desert out there, and we hooked the boat trailer to the car and made the journey down to San Diego Bay, to launch the boat. We actually got out of the Bay just into the open Pacific Ocean, the waves were horrendous, and I remember clinging onto the boat and in my mind to my life.  His wife was with us too, and they seemed to be doing a lot better than I was feeling.  Anyways, we turned around, and were promptly stopped by the water police patrol, who inspected the boat for safety equipment and what not.  Something was missing, I don't remember what, and he got a citation written up and they let us go.  Then we still had to haul that boat out of the water onto the trailer and haul it back to Spring Valley.  A lot of work for an hour or so on the water and having basically a terrible time, which of course I didn't mention.   I am having a better time in Spring Valley right now.

This is superb!  Thank you so much to everybody for helping out.  I really appreciate all the ideas and information.  When I first got into history I read this great book (The Historian's Craft, by Marc Bloch which is one of the landmark books of the discipline) in which, in part, he argues that historians are detectives.  I think this thread is perfect evidence of that!  What a great chase it's set up to be!

I'm doing as much research as I can on the area however, being on the opposite coast access to information has been limited - until now!  The quarry aspect is an interesting one and something which I will certainly refer to once I'm able to actually visit some nearby archives (likely next summer at the earliest).

The information on the central office is also vital as this places the payphone with an information network which fits perfectly with my method.  Should it be of interest, the telephone number on the phone is (619) 470-9728.  The listed call rate is 35 cents.  Based on some other information and the stamping on the coin return door, I believe the phone was manufactured between 1984 and 1990 (whether it was the first phone to be installed at the site, or whether the location and number existed prior to its installation still remains unclear).

I'm beginning to write up the project and will definitely be using all the information everyone has provided.  Please let me say thank you so much again to everyone on the board who has helped.  This is one of the most difficult projects I've undertaken and everything here is invaluable.  If the project remains as exciting as it is currently, I think it might turn out to be the best project I've ever undertaken!

Thanks again and I look forward to reporting back as things continue! :)

QuoteI'm interested in that payphone, simply because I actually have it!  I was able to purchase it for relatively little money and part of my coursework is to write its history.

Did you get the keys for the phone locks when you purchased it? Just curious.

I thought I would share some small payphone memories:

During the 70s/early 80s, I would always carry a dime in my wallet so I could make a call.  I remember the dime would indent the leather over time, so you could easily see it from the outside.   I became interested in collectable 3-slots WE payphones, because I used one at the bowling alley to call mom to come pick us up.

As an adult, I vividly remember the trepidation one often felt with outdoor phones as you approached.  Will it work?  Is it clean enough to "risk" making a call?   One always kept the handset as far away from one's mouth as possible to avoid contact.  The cords were short, so the ergonomics weren't always the best.  And then there were all the numbers you had to enter to use a credit card to make a call.  As Teleplay mentioned you did always check the coin return.....

I also remember the sales meetings in the '90s where the hotel payphone banks would fill during meeting breaks, and then empty again.  Now I feel compelled to announce a payphone to my kids whenever I see one, (and often wonder out loud how long it will be there).   Even though most of us would not want to go back to a world w/o cell phones, I do lament the loss of all those "friendly" (and some not-so-friendly) payphones that used to be nearly everywhere......

Great, I frankly have been enjoying the journey so far myself,
but I am not planning on working on a second Ph.D. for myself yet, LOL.

Having had that telephone number in the beginning would have saved some work, but now it is a confirmation of the work.

The office code 470 is indeed one of those in that central office.

It is also interesting that the number in one of the upper 9XXX ranges, 97XX.   Starting in 1955, the Bell System traffic engineers recommended (as written in Notes on Nationwide Dialing, AT&T 1955) for new installation that coin lines should preferably be assigned numbers in the 9XXX thousand block, because it would automate the detection of calls from pay phones, so that the operator didn't have to determine whether the caller was on a pay phone.

When you look at the map, you find that previously to being a built-out road, it was just Quarry Trail, and this still extends Quarry Road today for some distance in the terrain, without pavement.

So, have you called that number ?

Have you got your pay phone to work ?    These are collectors on this forum, and we make almost all of our phones work again.

A pay phone can be made to work again too, even correctly with a pay phone controller that generates the right signals that are needed.

Sorry!  I should have thought about that! - I apologize for the inconvenience! :-[

Yes I have.  It's been disconnected.  I've not been able to find anything more as yet (at least which is reliable information).

Not yet, though I'd love to.  Part of the reason it was cheap was because the keys are inside (you can hear something which is not coins when you tip the phone up).  I would love to access the inside, however from my research I am certain this will involve drilling and I just don't have the resources or tools (yet...) to do so.  As a former band technician I'd love to get involved with the mechanics and electronics however this will have to wait until a bit later unfortunately!

Thanks so much again for the help and sorry for not providing the phone number earlier in the thread!

Since you know where the phone was installed, it's likely that you can get the correct 29A key for the upper housing, so drilling of that lock may not be necessary.

The vault locks, on the other hand, are individually keyed.

Hi again everyone,

My apologies for the delay in replying - being the end of the semester, last week was rather crazy.

I just wanted to say thank you again to everyone who helped me out.  I massively appreciate the help and the information provided was invaluable and yielded many excellent references for my paper.  Most importantly, it has made for an excellent start to a larger project which I will continue to develop.  My goal now is to refine my ideas, work out how the structure of the project will look as it expands, and then seek new information accordingly.

I will keep everyone updated as things develop and thank you all very much once again. :)

Many people that live here in Anza, Ca. Vacation or just go weekending at Spring Valley.
I will pass on this request for information.
