Covert Subject: TSPS and TOPS TSPS (the Bell system's advanced operator system, Traffic Services Position System) does handle most long-distance traffic for Step-by- Step Central Offices as well as most operator traffic for all types of Bell System (and often nearby independent) COs. However, it very rarely handles non-operator intertoll, except in the case of XBar international. Lauren, can you give me the NPA-NXX of any XBar in the US with IDDD via TSPS. I'd like to take a look at it. I'd also like to take a look at any XBar doing normal inter- toll via TSPS, if you can give me an NPA-NXX. ------------------------------ Date: 3 Sep 1981 1424-EDT From: John R. Covert Subject: Speaking Clock A good job is usually done of blocking things like the speaking clock or Dial-a-disc from incoming toll calls. It can be done in a number of ways. For example, the number Lauren gave for the dial-a-disc recording is too short to be dialed from the North American Network. Numbers in the UK must be at least 9 digits long (counting the country code). Thus 011-44-222-06 is two digits too short to be dialed. It is also possible to class mark certain things so they can't be dialed. In Step, you do this by not building out the switch-train. In more modern offices it is done with hardwired or software "attri- butes". Certainly we can find some numbers that do work. However, if they don't go off-hook, and don't charge, then the Federal Authorities may consider it Toll Fraud, especially if Bell Security tells them to. If they do go off-hook, it's an awfully expensive way to get the time. ------------------------------ Date: 3 Sep 1981 1435-EDT From: John R. Covert Subject: Learning about telephony I recommend doing what I did years ago. Go to a good tech library and read every copy of the Bell Labs Record you can get your hands on. Then go to the Bell Sys Tech Journal for more detail. I also subscribed to the Record for a few years. ------------------------------ Date: 3 Sep 1981 1803-EDT From: Gene Hastings Subject: SMB's question in V1,#8(Wed. 2 Sept) It's always been my impression that pushbutton phones are preferred for pay stations because of their greater resistance to vandalism (such as no finger wheel to be pried off). I suspect that they may also be more reliable in general. Has anyone heard of any operating company installing ersatz PB phones (i.e. ones that have a pushbutton face but put out pulses) for whatever reason? For that matter, what do such dials do when you press "#" or "*" ? Gene ------------------------------ Date: 3 Sep 1981 1617-PDT Subject: TSPS From: GILLIGAN at USC-ISID Folks interested in learning about TSPS should have a look at the July-August 1979 issue of The Bell System Technical Journal (part 1). This is a special issue dedicated entirely to TSPS and includes photos and and diagrams of the operator's console in enough detail to make out the legends on the keys. Also in this issue are a few articles describing the Automated Coin Toll Service. ------------------------------ Date: 1 Sep 1981 1127-PDT From: Ian H. Merritt Subject: Re: [Bob Knight] Bill paying by telephone - a demo. I called that thing last night (I wonder if they are noticing a huge influx of users (from this list, little do they know...) suddenly calling that thing at all hours of the night) and found it interesting, however not unfamiliar. I have seen uses of votrax and other tape-patched speech systems (which I believe this is), used interactively with touch-tone input from users. How many readers of this list are familiar with the so-called 'District Data Processing System' in Michigan. This system was used by phone freaks for many years, since its access codes were almost anything 3 digits long. 123, 111, 222, 333, 321, etc were valid user idents. This system was done with tape-patching, and I think it still exists, however the old phone numbers (800-521-8530, Admin at 313-322-3405) have long been defunct. There is an order-entry system, using Votrax speech on 800-638-8927, which requires a *LONG* identification string, which provides for selection of one of several special services. At 800-631-1146, there is another Votrax system, however I have no idea what it is used for. A little over a year ago, someone showed me a system at Ralston Purina to which the numbers have been changed, using interactive speech or tones. If you talk to it, it talks back; if you tone to it, it signals you with tones. This system is the first commercial application I have seen of speech input in which there was a reasonable hit ratio. The dialog was something like the following: [User calls system] [Long pause, during which time, if a touch-tone is received, tone mode is then selected for the duration of the call] System: [In a sexy female sounding, but synthesized voice] Authorization number, please... User: [Speaks as clearly as possible, annunciating each syllable] Five System: Five User: Seven System: Seven User: Five System: Nine User: NO! System: Sorry. User: Five System: Five User: Three System: Three User: END! System: Thank you. Destination number, please... [Dialog continues until the numbers are all in, then the system when operating under normal conditions, will proceed to place the call the user entered with the 'Destination number'] If the system receives 3 errors, while trying to read the same digit, it responds with 'Sorry: Were having difficulties' and goes to reorder tone. Know of any others like this?
