PSTN network topology
A PSTN network topology is the switching network topology of a telephone network connected to the public switched telephone network (PSTN).In the United States and Canada, the Bell System network topology was the switching system hierarchy implemented and operated from the late 1940s to the 1980s for the purpose of integrating the diverse array of local telephone companies and telephone numbering plans to achieve nationwide Direct Distance Dialing (DDD) by telephone subscribers. It was the precursor of the world-wide interconnected public switched telephone network (PSTN).The ideas originated in the Bell System in the United States, but were soon adopted by other countries where telephone operators were facing similar issues, even when service smaller geographic areas. The system in the United Kingdom implemented by the General Post Office resulted in fewer switching levels than the Bell System.
