The appraisal of delays in gate-type operation

IN RECENT years, increasing use has been made of gate-type lockout circuits in telephone switching systems. When such circuits are employed, a certain amount of delay occurs before service is given to any of the components connected to the gate; as a matter of fact one of the purposes of the gate lockout circuit is to provide a reasonably equitable distribution of delays where delays are unavoidable. To the writer´s knowledge there has been no analysis published on the congestion thus introduced by gate operation, and in view of its importance in present-day circuit technique a tentative analysis is attempted in the following.
