Supplemental Conceptual Design Study of an Integrated Voice/Data Switching and Multiplexing Technique for an Access Area Exchange.

摘要

The overall Phase I SENET-DAX study was directed towards investigating the concept of an integrated voice/data switching system based on dynamic allocation of variable-sized increments of a flexible time division multiplexing transmission system. This permits a unified transmission and multiplexing structure that exhibits a high level of transmission efficiency not obtainable by separate voice and data systems, while supporting widely disparate types of communications. The purpose of this supplemental report is to analyze further the integrated voice/packet/data transmission concept established in the Phase I effort, and to determine how it may be realized from generally available hardware, software, and firmware processing modules. Alternate conceptual system designs for an access area exchange model were investigated and an experimental approach to examine the integrated voice/data switching and multiplexing technique for access area application was formulated. In contrast to Phase I, the conceptual designs developed in this report emphasize processor architecture and software structure for an experimental model whose primary purpose is to demonstrate the workability of the basic SENET-DAX transmission concept in a realistic environment.
