The intent is to achieve a single comprehensive DCME Recommendation based on the current work of various Administrations, recognized private operating agencies and recognized standards bodies. Consideration is being given to make the CCITT Recommendation on DCME applicable to all circumstances where DCME is required (i.e. cable and satellite, various signalling protocols, etc.). It will be of such detail thatequipment conforming to it, but obtained from different design sources, would work together satisfactorily within a single system.
