	Automatic number announcement circuit - Wikipedia, the free encyclopedia
		An automatic number announcement circuit (ANAC) is a special telephone number that is meant to be used by phone company technicians and other telecommunications technicians to determine the phone number of a particular line.
		This number connects to a computer at a local central office which uses a voice synthesizer or digital samples to "speak" the phone number of the line calling in.
		Because this system is based on automatic number identification (not caller ID) and meant for phone company technicians, the ANAC system works with unlisted and even numbers with caller ID blocking.

		Automatic number announcement circuit (ANAC) is a special telephone number that is meant to be used by phone company technicians and other telecommunications technicians to determine the phone number of a particular line.
		The way ANAC works is fairly simple: A technician will call a local ANAC's phone number (in Connecticut, they would dial 970) this number connects to a computer at a local central office which uses a voice synthesizer or digital samples to "speak" the phone number of the line calling in.

		Automated coin toll service or ACTS, the automated operator you get with a 1+call, is also made possible by accessing these line information data bases or LIBDs.
		The other grounds the circuit itself.(2) Thus, a coin deposit is represented by a grounded circuit with, supposedly, a certain amount of resistance.(3) The CO, possibly tone, opens the ring lead on its own end.

		The bottom line is that, for a reasonably large, complex source module, you can get the compiler to produce a number of different object modules simply by changing your optimization switches, so your decompiler will also have to be a deoptimizer which can automagically recognize which optimization strategies were enabled at compile time.
		The operator will give you the number and then you will hear a message similar to "Your call can be completed automatically for an additional 35 cents." When this happens, you can then use ACTS tones.
		The reason is simple, even though I was initiating my call to an 800 number from a different exchange (Class 5 office, aka Central Office) in each case, when the 800 call was routed to the toll network it would route through the New Haven #5 Crossbar toll Tandem office.

		But, I have found that if you get the ANI passed by the PBX by dialing an ANAC (Automatic Number Announcement Circuit, which will say back the number you're dialing from), then use the VM system's PBX to dial the PBX's area code + 700-1212, you'll hear who the local service provider is for them.
		That local number is the number "behind" the toll free number, as It's said to be.
		Since, most toll free numbers are nothing more than numbers that forward your call to some standard 10 digit phone number somewhere.

	The Alt.Phreaking FAQ
		Numbers receiving realtime ANI are connected to their CO or toll center via digital trunks which send data packets back and forth.
		If this were a name-and-number Caller ID data stream, the number would be followed by a delimiter (01h) and another message length byte to indicate the number of bytes in the name.
		This is calculated by adding the value of all the other bytes in the data message (the message type, length, number and name data, and any delimiters) and taking the two's complement of the low byte of the result (in other words, the two's complement of the modulo-256 simple checksum of the CID data).

		If you see a number which looks like a phone number, but has one of those leading codes, it is actually a TWX machine.
		To get the actual number is free (there are qualifications that I don't deal with), but to get it 'turned on' in a LATA costs you money, depending on (1) How many prefixes you're getting, (2) whether it's 800 or 900 service, (3) How many Tandems/End Offices are in the LATA.
		Most telephone users from the United States are quite familiar with 800 service: a number that they dial and incur NO charge (not even message units in most [all?] areas).

		Since most payphones are now connected to outgoing-only phone lines, one might wonder what use a list of payphone numbers is. The answer is simple: with a complete payphone directory you can locate calls from payphones with Caller ID just as you already can from residences and businesses.
		Just send email to dethmeow@artofhacking.com with the phone number, exact location (including the floor of the building, address, cross streets, if it's in a bank of phones, and so on), and if known, the kind of phone.
		In most cases, the number is printed on the instruction card on the phone or on a little phone number card under the handset cradle.

		The audio circuit uses AGC and a voice bandpass circuit from 300 Hz to 3000 Hz for normal telco voice, and 100 Hz to 10 kHz for hi-fidelity voice.
		A digital conversion circuit or command capture circuit is also be helpful, but really isn't required unless you dealing with higher threat situations.
