Native ISDN BRI S0/T0 event

The ISDN BRI S0/T0 physical events are generated by the analysis process on the PH link when the physical interface type is based on ISDN BRI S0/T0. Every transition of state of the physical interface (INFO signals, power supply) generates an event.

The binary event structure is defined in the Clarinet-API.

The edition of the ISDN BRI S0/T0 physical events without any decoding/formatting allows to display the successive states of the physical interface.
