Abstract

A method of performing errorless switching in a ring network having one or more rings and a plurality of transmitting routes. The transmission delays or lengths of at least predetermined sections of the routes are compared, and the comparison is used to determine the value of a first delay added to one of the routes. Another delay is added to enable phase alignment of signals so that errorless switching can be achieved. The delays are then adjusted to reduce cumulative delays which could degrade the quality of data transmission.
