Metering Tones
FXS gateways can generate 12/16 KHz metering pulses towards the Tel side (for example,
for connection to a payphone or private meter). Tariff pulse rate is determined according to
an internal table. This capability enables users to define different tariffs according to the
Source / Destination numbers and the Time-of-Day. The tariff rate includes the time interval
between the generated pulses and the number of pulses generated on answer.
