  1. http://localcallingguide.com is another great resource.
  2. Yup, they're dropping like flies. Now that it's April, I bet there are less than 5 left. Wonder how we can test the remaining ones?
  3. Is that number consistent with all 1AESSes?
  4. TV Stereo used a different pilot for the L-R signal. Otherwise it was almost identical to FM Stereo. Yup, the 800 MHz band we know and love for cellular (the infamous "A" and "B" bands) were the old UHF channels 70 to 83. With the advent of ATSC (now known retroactively as ATSC 1.0), channels 52 to 69 were removed in 2009 and those are now known as the 700 MHz LTE band. With the upcoming ATSC 3.0 that's around the corner, UHF channels above 37 will be removed. That will become more bandwidth, probably for 5G wireless. In addition, TV stations are volunteering turning in their licenses, which will free up even more spectrum. With ATSC 3.0, the 6 MHz channels will handle up to 4K video and you can compress the living snot out of 1080, 720 and 480 (tons of sub-channels). So the now pretty much empty UHF band will shrink once again and will be littered with wireless.
  5. I know on the DMS-100 Centrex where I work, you use the vertical service code before dialing 9 for outside line. So it's *67 (or 1167) + 9 + number. Otherwise as TP said it could have been misinterpreted as dialing 911. (Which is why they recently changed it for us to 9+911)
  6. What's the best way to check to see if a 1AESS office has been cut over to a new switch? If I recall, there were certain test numbers you could call on a 1AESS that only existed on that platform that disappeared when it was cut over to a new packet switch. I believe that it's now early April that all of the 1AESS switches are now gone. However, I do want to check to see if there are any left.
  7. Carriers couldn't wait to get rid of AMPS. It was a spectrum hog. They could compress a lot more GSM and CDMA calls in the same channel space. In fact, AT&T finally got rid of 2G (TDMA) in January 2017. Again, lack of market share, spectrum hog, and everyone had finally moved on to GSM or LTE. In fact, 5G (actually not really a consumer standard) is on its way soon. More signals, less need for the older crap. It was pretty amazing. In 2008 AMPS went away, in 2009 NTSC (analog) television went away. And in a few years, the current digital ATSC will go away (ATSC 1.0) because ATSC 3.0 is around the corner. And that will use even less spectrum because the FCC is giving that away to the cell companies. ATSC 3.0 uses more compression than the current ATSC 1.0 does. And don't get me started on the landline side of things. I see huge changes in the next 5 to 10 years. Ain't technology grand?
  8. I'd like to hear those tapes as well. Really loved that series! One of the masterminds behind that contacted me via the website a few months ago.
  9. Not sure what they use as their platform, but it's not the traditional OSPS that we've been used to with the post paid platform.
  10. Maybe if you have AT&T as your LD carrier you can still have a post-paid card? Mine was turned off mid-October. (It was a direct billed to a credit card since I haven't had AT&T as my LD carrier for... 15 plus years!) I've had a calling card with AT&T for probably 20 years. Sad it was finally deactivated.
  11. Red Boxes only worked if you could connect to ACTS on either OSPS (5ESS) or TOPS (DMS-200). ACTS on AT&T's OSPS died about 2004 timeframe, maybe even a couple of years earlier. TOPS on DMS-200 may still be around for Intra-LATA calls. But that's really rare now. Frontier was the last company I found that had that, but that was about 2-3 years ago. I tried back in 2015 and was unable to dial a long distance call to TOPS. It may be gone by now. Bottom line - Red Boxing is pretty much D-E-A-D.
  12. Four wire trunks, local and toll switching. In other words, a tandem when a 1ESS/1AESS was a part of the hierarchical structure of the long distance network.
  13. Oh yeah, forgot those HLE switches! (1AESS high-low) I'll add that to the list. Looks like that gets replaced 1st Qtr of 2017 Thanks!
  14. I'm working on a report of the remaining 1AESS switches. Based upon what I know of at the moment, there are probably less than 20 1AESS switches in the US. The reason that I'm not sure is that according to AT&T regulatory documents, 20 of the 28 that I've researched that I believe still exist as of the start of 2016 have expected retirement dates. The other 8 I can't find, hence they either do not yet have a retirement date set or have already been sent to the scrap heap. The ones with 1st or 2nd Quarter 2016 are probably gone by now. So my rough estimate at the moment is between 13 and 21. I'll be working with a contact in the industry to help refine this list in the coming weeks, but I thought I'd share what I have found so far: Current CLLI State Ratecenter Wirecenter Expected Retirement JCVLFLRV38E FL Jacksonville Riverside 3rd Qtr 2016 JCBHFLMA24E FL Jacksonville Beach Main *2nd Qtr 2016 ATLNGAAD69F GA Atlanta Adamsville No info found ATLNGACD28F GA Atlanta Columbia Drive 3rd or 4th Qtr 2016 ATLNGAGR24F GA Atlanta Gresham *2nd Qtr 2016 ATLNGAHR79E GA Atlanta Hollywood Road *1st Qtr 2016 ATLNGAWE75F GA Atlanta West End *1st Qtr 2016 FRBNGAEB96A GA Atlanta South Fairburn-East Broad 4th Qtr 2016 AGSTGAFL79C GA Augusta Fleming East No info found CRTNGAMA83C GA Carrollton Carrollton 4th Qtr 2016 LGRNGAMA88C GA Lagrange Lagrange Main No info found SVNHGADE35C GA Savannah Derenne No info found WRRBGAMA92C GA Warner-Robins Main 1st or 2nd Qtr 2017 WYCRGAMA28C GA Waycross Main 3rd Qtr 2016 LFYTLAMACG1 LA Lafayette Main No info found LFYTLAVMCG0 LA Lafayette Vermillion 4th Qtr 2016 SHPTLAQBCG0 LA Shreveport Queensboro 4th Qtr 2016 SHPTLAHDCG0 LA Shreveport South Highland 1st or 2nd Qtr 2017 GDRPMIBL770 MI Grand Rapids Bell No info found STLSMO40CG0 MO Ladue Florissant No info found NSVLTNINCG0 TN Nashville Inglewood *2nd Qtr 2016 BUMTTXTECG0 TX Beaumont Terminal 4th Qtr 2016 DLLSTXHACG0 TX Dallas Hamilton *2nd Qtr 2016 DLLSTXWHCG0 TX Dallas Whitehall *2nd Qtr 2016 ELPSTXNECG0 TX El Paso Northeast 3rd Qtr 2016 FTWOTXWACG0 TX Fort Worth Walnut *2nd Qtr 2016 DLLSTXGPCG0 TX Grand Prairie Grand Prairie 3rd Qtr 2016 ODSSTXLICG0 TX Odessa Lincoln 1st or 2nd Qtr 2017 The ones with an asterisk are probably gone as of August 2016 based upon AT&T regulatory documents. So as you can tell, there will be most likely three 1AESS switches still around by early 2017 (Warner-Robbins, Shreveport South Highland, and Odessa Lincoln). So the countdown will be to see which one of these three will be The Last of the Mohicans, so to speak. The end is getting closer. Time to work on getting those recordings before they're gone for good!
  15. Way off topic - I still see vestiges of old phone companies everywhere I go. It's not so odd when it's when one independent got bought by another. But when a Bell area gets sold to an independent, that's where it's sometimes surreal. And Jman is right, 483 is still around and used by Verizon. Most of the old GTE area is still treated as such. Where I used to live (and where I work), we still see a lot of Contel signage. (Contel -> GTE -> Verizon)
