Current and medium term developments in switching
David M. Leakey · Philosophical Transactions of the Royal Society of London Series A Mathematical and Physical Sciences · 1978
Abstract The current and medium term developments in switching are characterized by the extensive use of stored program control, digital switching and common channel signalling. In implementation terms, integrated circuit silicon semiconductor technology dominates. From the user’s viewpoint, these developments should result in large reductions in equipment size and procurement times, improved operational, maintenance and subscriber facilities, and an enhanced ability to cope with the evolving needs of both public and private telecommunication networks.
