Summary

The DCME Package is used for interfacing digital circuit multiplication equipment (DCME). DCME types are for instance defined by Recommendations ITU-T G.763, G.767 or G.768. There is a signalling interface defined between DCME and a so-called "international switching centre" (ISC). Recommendation ITU‑T Q.50 defines such an interface. The DCME Package scopes DCME with Q.50 interfaces.

This revision of Recommendation ITU-T H.248.42 adds new parameters for events, to allow the media gateway controller (MGC) to resynchronize itself in the event it loses track of this state.
