The efficiency analysis of the swiching fields of an ewsd v.15 digital switching system
Because of wide introduction of EWSD digital switching system on modern telephone networks, the problem of the economic efficiency of its operation is highly compelling. For the solution of this task at the stage of the digital switching system design it is necessary to select an optimal switching field structure. In this work the structures of single-, three- and five-link switching fields of digital switching system EWSD V.15 built on two standard time and three spatial modules at five capacities have been simulated.
