Abstract:
A trunk line exchanging system comprising:line switches disposed at a front position of a trunk line exchanging system comprising a plurality of trunk lines for servicing a region, said line switches facing another trunk line exchange system, wherein the number of trunk lines for a region is varied by executing a re-distribution operation of trunk lines to cope with variation of traffic at each region by controlling opening and closing of said line switches to redistribute trunk line connections from lower traffic regions to higher traffic regions;traffic managing means for managing the traffic of each region;trunk line exchange means installed at each region for executing region trunk line exchanging; andinterface means connected with both said trunk line exchange means and said traffic managing means for receiving and sending signals for controlling at least one of activity ratio of each region, trunk line closing, and trunk line switching;wherein the number of trunk lines to be allocated to each region is re-distributed based on the activity ratio generated by said trunk line exchange means located at each region.
