Applications
Periodic Pulse Metering
All trunk units on the NTCK16AX trunk card can be individually configured
to support the Periodic Pulse Metering (PPM) feature.
Note: PPM is available on the NTCK16AX trunk card. It is not
supported on the NTCK16BX trunk card.
PPM allows the user of a telephone to keep an accurate record of Central
Office calls for billing or administration purposes.
