Abstract
A switching unit, equipped with a plurality of port cards and a plurality of switch cards connected in a non-parallel fashion to the port cards. Each port card has a first M-way commutator and a second M-way commutator, wherein the total number of first M-way commutators over all the port cards is N and wherein the total number of second M-way commutators over all the port cards is also N. Each switch card has a first N-way commutator and a second N-way commutator, wherein the total number of first N-way commutators over all the switch cards is M and wherein the total number of second N-way commutators over all the switch cards is also M. Each switch card further has a unit for controllably time switching a plurality of signals output by each first N-way commutator and providing a plurality of switched signals to the corresponding second N-way commutator. The mth output of the nth first M-way commutator is connected to the nth input of the mth first N-way commutator and the nth output of the mth second N-way commutator is connected to the mth input of the nth second M-way commutator, for 1<=m<=M and 1<=n<=N. The commutators and the time switching units cooperate to provide non-bloc…
