The Green Box generates useful tonessuch 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 a
|
|||
|
|
fortress station, but must be used by the CALLED party. The tones (hz) are:
|
|||
|
|
|
|||
|
|
COIN COLLECT 700 + 1100
|
|||
|
|
COIN RETURN 1100 + 1700
|
|||
|
|
RINGBACK 700 + 1700
|
|||
|
|
|
|||
|
|
Before the called party sends any of these tones, an operator released
|
|||
|
|
signal should be sent to alert the MF detectors at the CO. This can be done
|
|||
|
|
by sending 900 + 1500 Hz or a single 2600 Hz wink (90 ms) followed by a 60 ms
|
|||
|
|
gap and then the appropriate signal for at least 900 ms. Also, do not forget
|
|||
|
|
that the initial rate is collected shortly before the 3 minute period is up.
