Green Box Plans by the Jolly Roger
|
|
|
|
Paying the initial rate in order to use a red box (on certain
|
|
fortresses) left a sour taste in many red boxers mouths, thus the
|
|
green box was invented. The green box generates useful tones such as
|
|
COIN COLLECT, COIN RETURN, AND RINGBACK. These are the tones that
|
|
ACTS or the TSPS operator would send to the CO when appropriate.
|
|
Unfortunately, the green box cannot be used at the fortress station but
|
|
must be used by the CALLED party.
|
|
|
|
Here are the tones:
|
|
COIN COLLECT 700+1100hz
|
|
COIN RETURN 1100+1700hz
|
|
RINGBACK 700+1700hz
|
|
|
|
Before the called party sends any of these tones, an operator realease
|
|
signal should be sent to alert the MF detectors at the CO.
|
|
This can be done by sending 900hz + 1500hz or a single 2600 wink (90 ms.)
|
|
Also do not forget that the initial rate is collected shortly before the
|
|
3 minute period is up. Incidentally, once the above MF
|
|
tones for collecting and returning coins reach the CO, they are
|
|
converted into an appropriate DC pulse (-130 volts for return and
|
|
+130 for collect). This pulse is then sent down the tip to the
|
|
fortress. This causes the coin relay to either return or collect the coins.
|
|
The alledged "T-network" takes advantage of this information.
|
|
When a pulse for coin collect (+130 VDC) is sent down the line,
|
|
it must be grounded somewhere. This is usually the yellow or black wire.
|
|
Thus, if the wires are exposed, these wires can be cut to prevent
|
|
the pulse from being grounded. When the three minute initial
|
|
period is almost up, make sure that the black and yellow wires are
|
|
severed, then hang up, wait about 15 seconds in case of a second
|
|
pulse, reconnect the wires, pick up the phone, and if all goes well,
|
|
it should be "JACKPOT" time.
