  1. 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?
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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!
  8. 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!
  9. 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)
  10. That's amazing that Nokia is now the support group for the 5ESS, DCO, EWSD and GTD5-EAX. And like you said, no longer the support for the 1AESS. Hence the big and final push to get them cut over to Genband G6 switches.
  11. I wonder how many will be left by the end of this year? Most, if not all of the ones I was aware of are slated to be replaced by the end of the year.
  12. It all depends. When I moved to a house in GTE territory, they had the system you said. While I was there they merged with Verizon. I dropped two of my voice lines (leaving one) and they left the battery on but no dial tone. But when lived at a small independent (which has been since taken over by a larger one), they had a system where when you lifted your receiver you got a recording. I recorded it at the time (late 2005) and I may still have it somewhere in my archives. If I can find it, I'll post it here.
  13. I'll have to see if I can find my card. I ordered my card back in 2004. If I can find it, I'll give it a scan (minus the number, of course.) p.s. I see you're also a ham radio operator. Plan on getting your General soon?
  14. Just got a notice today from AT&T. They are discontinuing post-paid residential calling cards effective October 1, 2016. I've had a post-paid calling card with them for a number of years, as a great way to test OSPS to see if they've programmed it correctly. (The late Mark Cuccia and I used to see which OSPS would get new area codes entered first, and which ones we needed to get on AT&T's butt to get entered!). Sad that in the era of unlimited long distance that another relic of yesteryear is about to disappear! See attached notice that I got.
  15. Does anybody have a list of the new N4E switches and the NPAs that they serve? I found one in Fort Myers, FL a while back (NPA 239). I think it's 151-T (I can't test it at home, need to do it from work where I have access to a real POTS line.)
