This Article will Focus primarily on the standard Western Electric
|
||
single-slot coin telephones (aka fortress fone) which can be divided into 3
|
||
types:
|
||
|
||
* Dial Tone First (DTF)
|
||
* Coin-First (i.e. it wants your money >before< your recieve a dial tone)
|
||
* Dial Post-Pay Service <PP> (You pay after the person answers)

Depositing Coins (Slugs)
|
||
---------- ----- -----
|
||
Once you have deposited your slug into a fortress, it is subject to a gamut
|
||
of tests. The first obstacle for a slug is the magnetic trap. This will stop
|
||
any light-weight magnetic slugs and coins. If it passes this, the slug is then
|
||
classified as a nickel, dime, or quarter. Each slug is then checked for
|
||
appropriate size and weight. If thses tests are passed, it will then travel
|
||
through a nickel, dime, or quarter magnet, as appropriate. These magnets set
|
||
up an eddy current effect which causes coins of the appropriate characteristics
|
||
to slow down so they will follow the correct trajectory. If all goes well, the
|
||
coin will follow the correct path (such as bouncing off the nickel anvil) where
|
||
it will hopefully fall into the narrow accepted coin channel.
|
||
|
||
The rather elaborate tests that are performed as the coin travles down the
|
||
coin chute will stop most slugs and other undesirable coins, such as pennies,
|
||
which must then be retrieved using the coin release lever.
|
||
|
||
If the slug miraculously survives the gamut, it will then strike the
|
||
appropriate totalizer arm causing a ratchet wheel to once for every 5 cent
|
||
incriment. (e.g. a quarter will cause it to rotate 5 times)
|
||
|
||
The totalizer then causes the coin signal oscillator to readout a dual
|
||
frequency signal indicating the value deposited to ACTS (a computer) or the
|
||
TSPS operator. These are the same tones used by phreaks, in the infamous Red
|
||
Boxes.
|
||
|
||
For a quarter, 5 beep tones are outpulsed at 12-17 pulses per second (PPS).
|
||
A dime causes 2 beep tones at 5-8.5 PPS while a nickel causes one beep at 5-8.5
|
||
PPS. A beep consists of two tones 2200 + 1700 Hz.
|
||
|
||
A relay in the fortress fones called a 'B' relay (Yes...there is an 'A'
|
||
relay!) places a capacitor accross the speech circuit during the totalizer
|
||
readout to prevent the 'customer' from hearing the Red Box tones. In older 3
|
||
slot fones, one bell (1050-1100 Hz) for a nickel, 2 bells for a dime, and 1
|
||
gong (800 hz) for a quarter, are used instead of the modern, dual-frequency
|
||
tones.
