That setup looks to be mostly 1980's tech. The round "Bell Cells" in plastic racks is a dead giveaway, as well as the light blue racks themselves. In the 70's and earlier the cells were rectangular and sat on rubber mats on heavy steel racks, and the equipment racks were all "Telco Gray". The blue Bell System symbol on the wall is from the 70's and the AT&T logo is from the 80's.

Ahhhh yeah, now we’re talking lol!!

That’s mean.

Well I have a few of those cards, now I know I have pieces of an AT&T longlines installation

Please work on your microphone

Gusto Sana mam ser paupa lupa ko Gawin o cellsite

Ako poh si carmelita Reyes Timoteo Taga Apalit pang

glad they got rid of this brain melting garbage

That’s gigahertz. With a z. The z is never silent. Cause his name is Hertz. With a z.

Thank You!

in nov im taking my 4x4 group to check out the long lines equipment bunker on razor rd near barstow ca. there is also a unmarked att microwave antenna close to anza borreigo. down town LA has an interesting building next to the Japanese embassy, similar to that spooky building in New York.

I was told, after I hired in as a systems tech for SWBT, in 1999, that those big old batteries were the same batteries they use on submarines. Even though I was a U.S. Navy submariner for 6 years, I can’t confirm that. Our batteries were hidden away in the battery compartment in the forward bottom part of the sub, which the interior communications (“IC men”) guys took care of. (I worked on ballistic missiles.) They’ll definitely hold a charge for a while. They were full of clear sulfuric acid, and the containers were clear as well. So when that site gets gutted out, that’ll be a big hazardous ⚠️ waste issue for them.

This is the first mention of frequency bands used on this system. Crazy to think that today, the 1-6 GHz band is the most valuable part of the entire radio spectrum. I would have expected that the 80-120 GHz band would have been used, as this range is unusable for satellite communication but is still in a range where atmospheric attenuation is not enough to block focused signals. But also thinking that we didn't have the electronic equipment at the time to reliably generate that frequency.

I've been doing work for various cell carriers in Canada for almost two decades and i gotta admit I always enjoy entering a new shelter and seeing its layout. Nice vid!

It would be interesting if one of these Long Lines sites in fairly good condition could be restored for use as a museum so visitors could go and see intact original equipment (doesn’t have to be operational, but would depict what is was like back in the day. It should also have an original tower with the horns in place (again, not necessarily operational, but intact). These sites are extremely historic and some which are in good condition, preserved. I know that in downtown Los Angeles, there is an AT&T Long Lines site with a mid-century style concrete tower that holds the horn antennas. I think it is still there today!

I can’t get the ctcss code to save.

Those square ceiling braces, need to have 45 degree cross beams in the 90s to make them reliable and load bearing

“Curvature of the Earth” haha what a joke. Why is it that when a boat disappears “over the curvature”, you can bring it back with binoculars or a zoom lens?

It's not all forever silent. There may be a day with grid down situation these site's come back on line. Old technology is not dead... from a amateur radio operator. Nice my uncle worked for pack bell. There's a reason some of these old sites sit quietly. It's when the shit hits the fan it comes back on line.

You NEVER EVER air condition an uninsulated building ‼️You mentioned I believe that it never got above 87° with the windows open and the AC off. That is NOT acceptable for electronic equipment OR people❗️Can you imagine working in an office building all day in an 87° environment❓ The fact that you’ve focused all your attention on your equipment instead of a proper building environment makes me question your basic thought processes. This video gets an automatic 👎

Great video, but I would not do any ethernet patch cables less than 1 foot because of attenuation.

I would like to see the software! I also want to see how you are able to program the quantar with XP and possibly where one might find the software for one's self.

7:17 Port 1 is only a v.24 port. The later version of the Quantar had IP connections for system release 6.x and up. I'm going from memory, but I believe one visual difference was that the serial port on the IP Quantars were labeled CSS, not RSS. Port 1 was definitely available for v.24, but I don't think they ever enabled Port 2 for dual v.24 inputs. That right slot in the Quantar could also accommodate an internal UHSO module which for a very long time was used on UHF stations in support of NTIA specs for federal users. You're right though, that 2nd receiver module option was pretty slick.

Very nice.. I'd love to have a setup like that !

Your Windex bottle isn’t on the network?? 🤦 Great video, appreciate the share!

Interesting

I really enjoyed this video. Thank you for sharing!

what if you mount one of those unifi instant cams in front of the rack so you can get a live view in case there's a fault? maybe you can see some of the status LED's. and to take it a step further, make it so that there is audio coming out of the speaker and put a link to your livestream on the unifi instant cam so we can watch the lights flash and occasionally listen to some repeater audio :) 73 from austin.

Great video as always, I think it would be a cool video to show the software that you use for the Quantar.

Seems to be going well for you, suggest you remove IP address on controller. 73's G8WOF

I just bought one after seeing this video lol 😂

So the antennas had been removed already?

Hi. Great video. I get an error message when I go to upload to the radio. It says can't upload to radio without advanced system keys. How do I rectify that? Also the radio has a lot of trunk freqs in it that I don't need. How do I delete them? Thanks 73 Joe W2JJT

Fellow scoper here. Keep up the good work buddy

Nice tutorial and intro!

Harris - better radios with out motofailing price tag…. Better audio too

Great Video, love the content.

Love my 100p unity. I just wish the battery life was better

How much there is Nokia equipment in use in USA? Nokia used to make digital switchgear and such as DX200 from the late 70's and now of course 5G and such

You’ve got a squad car too? Lucky!

That old C band network was 4/6 GHz. The network handled what ever the phone company did. While telephone and TV were certainly a large part of it, they also handled data, though not to the level of today. I recall working on the multiplexing equipment. Starting at the bottom was what was called "Voice Frequency Carrier Telegraphy" (VFCT) which connected the old teletype and similar circuits over a voice channel. Then the voice channels were grouped and carried over either microwave, open wire lines or the new fangled digital T1 system. In microwave the channels were bundled into groups and super groups, to be carried over the radio link. Back in those days, a modem, which might be as fast as 2400B, required a dedicated, conditioned circuit and when carried over microwave were not placed on channels near the edge of the group, as the filter roll off would reduce the bandwidth of the voice channel. Also, those towers did not "broadcast". Broadcast is a specific term in telecom, which means from one point to many, as with radio broadcasts. Microwave links are point to point, with the signal focused on the other end. In fact, broadcast is one thing they did not want to do because a) it's a waste of signal and b) it might interfere with something else. A lot of telecom gear is -48V and if you have 3 power supplies, you likely need only 2, with the 3rd for redundancy, in case of failure. You should be able to pull out 1, without affecting anything. You say that equipment is old, but in fact looks fairly new. The stuff I used to work on was a lot older. For example, the batteries were in glass, not plastic. It sounds like you're confusing hard line with wave guide. You had shown wave guide earlier then started talking about hard line. Hard line is essentially rigid coaxial cable, but those microwave sites usually used wave guide as even hard line coax had too much loss. Anything with an 8 bit CPU is no older than 1974 or so. That shelf you were leaning on, near the end, appears to be a DSX panel. where DS1 (T1) 1.544 Mb circuits were cross connected.

'Nother day older and deeper in debt.

PEnn 6-5000! Some say it's the oldest continually operating landlline number in New York City.

"Southwestern Bell Long Lines" never existed.

Dang it, I AM NOT showing this to the wifey! 😊. I bought and installed a one tuber!

You can get ones that pump the condensed water out of the window. No bucket to drain which gets to be a hassle. A generator of sufficient wattage will run them during power outages, so you can cool whatever room you are in. Consider a generator which runs on propane which you can store forever, and which won't gum up your generator's carburetor in storage. All you need to do with a propane powered generator is change the oil every couple of days of run time, since the smaller ones don't have oil filters.

You need to put your exhaust hose above your intake hose. Otherwise, the hot air will rise from the exhaust and get sucked into the intake.

nice video, thank you. Does that one have a BTU rating?
