  1. NTS Is this the same NTS company that operated the COCOTs that Evan and Les played with in the 80s?
  2. -- Is alive and well in an office at the "Der Spiegel" magazine in Berlin (and you don't need xcoffee to see it) (reload this page to get the latest shot): ( If you're too young to remember:
  3. ==Phrack Magazine== Volume Four, Issue Forty-Three, File 21 of 27 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + + + + + The Telephony Acronyms and Abbreviations List from Hell + + + + + + by + + Crisp GRASP + + + +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Well, here it is, the list from hell. Sure beats the old lists of 100 or so three letter acronyms. The whole reason for this list is so that you can crack almost ANY bell document. This list came from a few lists (one in Phrack a while back) and a few other Telephony lists here and there. Though it must be noted (and i want to take credit for it) that well over half of the acronyms and abbreviations were typed in by me, inputed into my database (of course I am not about to give out my database). It is always a good idea to start a database, one will learn a lot faster. It is doing things scientific like, and for someone as compulsive as I, solving the puzzle of the telephone company was easy as pie. I must say that all the hackers I have meet, and talked to are all compulsive as hell <G>. I think it is just what it comes down to, who is willing to learn. Any ways here is two fields in my database, one small part, but worth it. Though i do not think it will be able to help most of you out, just gets into too much, and understanding which acronym goes where, and understanding what goes where is hard. Well good luck! Greets to Bell Northern Labs, never see too much from you press wise! and to SRI, should have come to Cal. hah (Don knows what I am talking about, his funding is short) -------------------------------------------------------------------------- 15M Fifteen minutes 15S Fifteen seconds 1CF Singal party coing first pay phone 1FAC Interface packs 1FB One party flat business rate 1OF One party official (telco) business line 2SPDT Partial dial timeout in the second stage of a traditional 2-stage international 2SPST Permanent signal timeout in the second stage of a traditional 2-stage international 2SVCA Vacant code in the second stage of a traditional 2-stage international outbound 2W Two wire (pair) (circuit) 2WAY Two-way trunk groups 300 Log command menu (SARTS command) 376 Log clear (SARTS command) 384 Write log (SARTS command) 385 Read log (SARTS command) 399 Log print (SARTS command) 3KHZ Three kilohertz 3RNGR Three ringer 3WO Third wire open 4W Four wire (pair) (circuit) 600 Test menu (SARTS command) 600B 600-ohm briged connection 611 Detail tests (SARTS command) 621 Macro command menu (SARTS command) 631 Automatic test command (SARTS command) 735T 735-ohm compromise termination ?A Action field contains an error ?D Data field contains an error ?E Error exist in the message but can ot be resolved to the proper field ?I Identification field contains an error ?T Time-out has occured on channel ?W Warning message A A side (lead) (pair) A Area A Telephone number or trunk group and member number from trouble A/B Two wire phone connection (T&R) AA Automatic answer AA Packet analog access line INTER/TRA blocal 1-26 AABS Automatic alternate billing service AAE Auxiliary access equipment AAR Automatic alternate routing AAX Automated attendant exchange AB Packet switch trunk INTER/TRA blocal 1-26 ABATS Automatic bit access test system ABATS Automatic bit access test system (DDS service) ABC Automatic bill calling (TSPS) ABF Abandon failure ABF Abandon failure (MDII) ABHC Average busy hour calls ABL Auxiliary Buffer oder word Left half ABM Asynchronous balanced mode ( -> SABME) ABME ABM extended ABR Auxiliary Buffer order word Right half ABS Alternate billing service ABS Alternative billing service ABSBH Average busy season busy hour ABT Abort ABV Above AC Administrative computer AC Alternating current AC Assembly code ACA Asynchronous communication adapter ACB Annoyance call bureau ACB Automatic call-back ACC Audio communications controller ACCS Automated calling card service ACD Automatic call distribution ACD Automatic call distributor ACDA Automatic call disposition analyzer ACDN Access Directory Number ACDN Access directory number ACE Assignment change establish ACE Automatic calling equipment ACES Aris cabs entry system ACF Advanced communications functions ACFA Advanced CMOS frame aligner peb2030 ACG Automatic call gap ACH Attempt per circuit per hour ACI Answer controller interface (IOM2 monitor command) ACIA Asynchronous communications interface adapter ACK Acknowledge ACK No acknowledgement wink ACK No acknowledgement wink (MDII) ACKDB Acknowledgement database ACM Address complete msg.

  4. What is it with all these television sets I've suddenly been finding dumped along roadsides lately? Most of them still seem to work and some are pretty nice for what they are. Just hauled a really nice working $2000 1997-model 50" Sony 3-CRT projection set out of a road stub by an apartment complex in Vancouver a couple Mondays ago. (The red tube is a little bit misaligned but can probably be adjusted. That I got to it before the vandals did is even more surprising.) With the dozen or so TVs now in my possession I'm almost starting to feel a little bit like shango066 must.
  5. I see that Phrack hasn't put out an issue since about June of 2012 and the new "paper feed" thing on hasn't been updated since last May. Does this mean the project is effectively dead and the existing site is now just an archive? Granted most of the articles in the last 15 years or so have been way over my head (and for the most part, pretty dry and academic) but I always have enjoyed the commentaries, profiles, letter section and the Phrack World News. Maybe they'll do something special this year, for its 30th anniversary. EDIT: This guy has done a really good job of collecting all the issues over the years: Apparently he also contributed some of the newer issues to Jason Scott's site.
  6. (Intentionally posted to "General Hacking" so the searchbots will find it.) Uh...yeah. It can't POSSIBLY be because he's stubbornly clinging to an obsolete, proprietary and frankly, unbelievably shitty codec that practically nobody supports any more. Oh no. It's gotta be all these "pirates". Gee and he wonders why he's losing money and subscribers. :rolleyes: You have to wonder about some people sometimes. It takes a real man to admit they've fucked up.
  7. +1 360 696 1280 (135.125 MHz) This is the ASOS at Pearson Air Park (KVUO). I have heard this same voice and robot-like delivery on some telco time-of-day announcements as well. The name Cognitronics usually comes to my mind when I hear these ASOS machines on the telephone or the radio, but I really doubt it's that. So basically what's the make and type of this system and who's the guy who did the voice samples? I first remember hearing this machine when I bought a new police scanner at Jantzen Beach in the early 90s and there is at least one Evan Doorbell raw tape from 1986 that has his voice on a time announcement (0803Z_02). These things are installed all over this region and I don't think I've called or tuned an ASOS in the Northwest during the last 20 years that doesn't have one running at some point during the day. Now here are a bunch more from the listings on Airnav: KSEA: +1 206 431 2834 KRNT: +1 425 255 6080 (after hours) KTIW: +1 253 858 6507 (after hours) KOLM: +1 360 943 1278 (after hours) KCLS: +1 360 740 5164 ("nnniner") (this must be a really old machine) KSHN: +1 360 427 3835 KGEG: +1 509 624 4406 KFHR: +1 360 378 8491 KPDX: +1 503 284-6771 KTTD: +1 503 492 2887 (after hours) (135.625 MHz) KHIO: +1 503 640 2984 (after hours) KSPB: +1 503 543 6401 KDLS: +1 509 767 1726 (135.175 MHz) KPDT: +1 541 278 2329 (118.325 MHz) 4S2 (Hood River): +1 541 386 2386 (135.175 MHz) not the same machine but this one is probably an antique as such things go; I first heard it in the mid 1980s on my dad's Reader's Digest ("Worldstar") multiband boombox. (early digital machine?)
  8. I look forward to hearing the recording of Steve's seminar when he shows up in 2020!
  9. 510-940-0102 as of a couple weeks ago, last time I was on.
  10. Pinned! This is definitely of interest to many people and shouldn't be buried over time.
  11. Guys, you need to start posting conf number changes in here since there's no more IRC...
  12. I didn't go (couldn't make it). If the current issue is to be believed, looks like there were some real shenanigans going on and I guess this is the one time in the past 20 years I DO wish I could have been there, to sit back, grab a Clubmate and popcorn and take it all in as the shit hit the fan. That's all I'm going to say because it gets political, though apparently politics was what caused Steve Rombaum to flake. Figures.
  13. It's definitely worth scanning, once I find some time to get going on it. In fact I started doing one 4-5 years ago or so (think it was 696-9xxx) but stopped after a couple dozen lines for some unknown reason. I did post a few from that scan in one of the "some numbers" threads. My main focus back in the day was on BBSes just because that's what I was into at the time, I don't think I was really aware of infrastructure and SCADA on the open PSTN then. Fax machines, don't know about today but as I remember they were all over the place a couple decades ago. Probably aren't nearly as many as there were but there's guaranteed to be a bunch -- VANCWA01DS0 services the downtown area where several law firms, insurance offices and a hospital are based (as well as the Clark County courthouse and all the area's administrative services), and a fax of a document is still legally considered admissible in court. It would really be a trip to find a working telautograph in the wild and on the network, assuming there are still any of those left.
  14. I remember scanning out then 206-694 and -696 on a metal-geared WE 500 rotary fone in the early 90s, looking for carrier tones (this was during the heyday of BBSes and the emerging commercial ISP industry and I was sort of into BBSing back then). I also remember my right index finger getting quite sore after about 75 numbers or so. What I would have given to have had an operator's dialing tool back then. I think I only did about 200 numbers or so on either, but gave up when I found that some phreak in GTE land (probably Camas) had already done the work for me and posted a full scan of VANCWA01CG0 to a local BBS. To this day I have no idea if they did it manually or by computer and I wish I had thought to ask. I think I may still have that half a ream of tractor-fed printout somewhere even though I probably haven't looked at it in 25 years. Hmmm, I still have that fone and 360-694/6 haven't gone anywhere. There are no more dialup BBSes around here that I'm aware of but I know there are a bunch of test lines and recordings on there... Of course back then we didn't have fancy things like electricity or indoor plumbing, the train brought us our mail once every two weeks and we walked 5 miles every day in waist-deep snow to get to school.
  15. I think what they do is submit a "prototype" with full RF filter complement to the F¢¢ for approval then actually manufacture them without, to cut cost. Supposedly that's been done a lot with compact fluorescent lights. I have Cree BA19-08027OMF LEDs in use and the ballasts in those things are effectively little solid-state wideband jammers below about 350 MHz, including airband (AM). An Energizer NiMH charger I have, when it's charging I can hear pulses of static over any transmission on VHF. Really makes it a pain in the ass when I'm monitoring Gifford Pinchot dispatch on 172.225. Those LEDs aren't nearly as noisy as fluoros were (nor do they put out as much UV to discolor plastic telephone housings in the vicinity!) but they're still far from silent. I was on a 58-mile bike ride today that took me into the Van Mall area and I went by the local Comcast headend. The building looks like it hasn't had any real maintenence since TCI was in there 20 years ago. They have an antenna tower out back and there's actually a small satellite dish (looks like a 1-meter unit (a.k.a. a "Muzak dish")) hanging off it by the coax! It's really and truly Comcastic.
  17. Apparently WBAI had that in the early 2000s. Eric demonstrated it in this Off the Hook program about 11 minutes in:
  18. New users SHOULD go to the "Welcome New People" thread in Nubie HQ at some point within your first few posts or so and introduce yourself to the world (handles only; never post your real name). You don't HAVE to if you don't want to, but it builds goodwill and helps others to know you better. Seriously. Linxz0rz:
  19. Apparently you can also do KP-NPA-xxx-yyyy-ST to outdial to the PSTN from Project MF. (God, how many decades since I've last talked about actually boxing a call?) Reading through that list it's amazing how much "improvement" it could use. For example, I should send them some of my intercept recordings I've collected over the years to put on their own codes. There's also a very good DOS program, "Phreakmaster", that doesn't need NET framework at all though these days it would require somethinglike DOS Box; that could go in the description of software blue boxes. // not actually complaining there, but...
  20. Zup.
  21. Just goes straight to reorder for me.
  22. I would like to reiterate the point, since so many people seem to be missing it. If you try to register your first name only (John, Fred, Becky, etc.), a full legal name (e.g. John Smith, Fred Meyer, Becky Thompson) or anything sounding remotely like one, your company name (especially when a corresponding URL is given), a URL/E-mail address or an alphanumeric string, you will in all likelihood be flagged as a spammer and removed due to the high volume of spammers attempting to register using such handles. Okay?
  23. This is a recording from Binrev administration: INSTRUCTIONS FOR NEW APPLICANTS - ANTISPAM GUIDELINES (TOS Addendum #69105.25F) This forum uses some pretty aggressive /dev/null style filtering. Every new user profile is scrutinized by a member of the Binrev Antispam Team. If you try to register your first name only (John, Fred, Becky, etc.), a full legal name (e.g. John Smith, Fred Meyer, Becky Thompson) or anything sounding remotely like one, your company name (especially when a corresponding URL is given), a URL/E-mail address or an alphanumeric string, you will in all likelihood be flagged as a spammer and removed due to the high volume of spammers attempting to register using such handles. (GMRS and HAM call signs fall into the category of full legal names. If you have one, don't register it.) I regret having to do this but unfortunately it's necessary. If this happens, and you are coming here legitimately (not with ill intent), please reregister using a proper handle not in violation of this paragraph. Profiles listing a postal address will be immediately considered suspect. The same goes if you enter bogus (or flat out irrelevant) things in your interests field (e.g. "Sport, friends, cooking, knitting"). If you enter the string "143040" anywhere in your profile as a new user you can expect to be permabanned. After registering your username and email address, Binrev will send you an automated E-mail post. You must use the link provided in the E-mail before you will be able to post. Please check your mail file and follow the instructions within 24 hours or your registration will be cancelled and you will need to reregister. Disposable email addresses are not permitted. If you register from Trashmail, Mailinator and others of that ilk please don't expect your account to last very long. Thank you for your full compliance.

  24. (this one's kind of old) God was fed up. In a crash of thunder he yanked up to Heaven three influential humans: Barack Obama, Vladimir Putin and Steve Jobs. "The human race is a complete disappointment," God boomed. "You each have one week to prepare your followers for the end of the world." With another crash of thunder they found themselves back on Earth. Obama immediately called his cabinet. "I have good news and bad news," he announced grimly. "The good news is that there is a god. The bad news is, God's really mad and plans to end the world in a week." In Russia, Putin announced to parliament, "Comrades, I have bad news and worse news. The bad news is that we were wrong: there is a god after all. The worse news is God's mad and is going to end the world in a week." Meanwhile, Steve Jobs called a meeting of his top engineers. "I have good news and better news. The good news is that God considers me the highest of the three most influential men on Earth," he beamed. "The better news is we don't have to fix the bugs in OSX."
  25. PG Steve Jobs Goes to Hell So eventually Steve croaks and goes to St Peter... St. Peter is embarassed. "I don't know what to do with you Steve ... you put a radio station in every pocket ... on the other hand you made OS/X. So I tell you what ... just chose between heaven and hell" Steve goes "Really, I can chose?" "Yes pick one" Peter says. Steve is very professionnal: "Ok, can I visit both before deciding?" "Ok, just go on. What do you want to start with?" Steve: "... why not start with hell?" And it came to pass that they both went to hell. Magnificient. Great beaches, plenty of sun and nude women every where, smiling at Steve. "That looks wonderful" Steve says. Now how about heaven? They then went to heaven. Magnificient. Great beaches, plenty sun, just no naked women. "Ok" Steve says, "I pick hell then." After a week St. Peter decided to visit Steve who was sent to Hell. The poor guy was on the floor, screaming, scratching the ground with his nails. He shouted at St. Peter: "No no no! I Can't stand it no more!" "What's wrong" St. Peter asked Steve goes "I don't understand, there is nothing to do with what I saw the first time. Where is the beach? The naked women?" And St. Peter: "That was just a free demo."
