Feature description
A new vintage 2 Mbps Digital Trunk Interface (DTI2) card is introduced with
this feature. The Italian Periodic Pulse Metering (PPM) feature enables this
new DTI2 card to count PPM pulses on Italian DTI2 trunks.
In Italy, a pulse on the A bit while the B bit is zero (P0UU) is considered a
valid PPM pulse. However, a pulse on the A bit while the B bit is one (P1UU)
should not be considered a valid PPM pulse.
