Summary

This Recommendation defines basic channel associated signalling (CAS) and R1 packages and supplemental CAS packages that, in association with the H.248 Protocol, can be used to control a media gateway (MG) from an external media gateway controller (MGC).

This revision adds a new read-only property containing the current CAS state of the termination, to allow the MGC to resynchronize itself in the event it loses track of this state.

This revision incorporates an update to the optionality of the “Pulse off” and “Pulse On” events.
