摘要

A method for searching a composite path for virtual carrier signals in a multi-stage clos - the switching network, with:Managing use state of connections between each stage,Search for possible tieable on the basis of the fluid paths use state of compounds and specifying a selected path of the possible paths according to the search for andManaging a channel connection state of the predetermined path,characterized in thatthe administration of the use of compounds between each step of a concatenated list and a bit map is used, wherein the bit map having:a vc3 - state - and - counting signal, including the condition of use of compounds, where the abbreviation vc referred to a virtual container,Tug - 2 - group - pointer, a channel state of the seven tug - 2 - groups as a hybrid ds3 - mode of the compound to be used, wherein the abbreviation tug a tributary unit group and the abbreviation ds a digital signal, andTug - 2 - transmit use information, which is a condition of the seven tug - 2 - groups reproducing.
