Abstract

A plurality of idle paths through a multistage switching network which are capable of establishing a connection between a particular line and a particular trunk are identified. Repeated selection of paths identified as idle, but actually out-of-service, is avoided by selecting successively different ones of the identified idle paths in a pseudorandom manner to complete the connection between the line and the trunk. The pseudorandom path selection is accomplished in response to predetermined portions of a pseudorandom pattern of binary bits.
