RCA, during the period from March 3, 1975 until April 1977 has been engaged in studies, brassboard development, analysis and experiments whose objectives have been to prove the feasibility of the concept of a Unified Node Employing Dynamic Channel Allocation. The unified node concept is the concept of integrating circuit switch, message switch, and packet switch functions within a single node so that the node can provide appropriate switching and processing services to a wide variety of voice and data users. The dynamic aspect of this concept deals with the composition of the internodal trunks. The internodal trunks employed are wideband trunk(s) (e.g. T sub 1 rates) which contain digitized voice time slots and non-real time data that is multiplexed in a frame structure and varied dynamically. Minimal restrictions are placed on channel data rates of voice data and the trunks are transparent to binary data transfers. See also Appendices 1 through 4.
