Abstract

PURPOSE:To improve the processing efficiency of the entire exchange by assigning a packet processing unit at every logic channel on a packet multiplex communication line so as to decentralize a load finely. CONSTITUTION:When a connection request between the logic channel line #11 of a packet multiplex communication line 2a and the logic channel line #21 of a packet multiplex communication line 2b exists, a connection controller 5 selects a packet processing unit 3a having the least load at this point of time. Then a command is given to a line exchange switch 1 so as to connect the logic channel lines #11, #21, accommodated in the packet processing unit 3a and lines #a2, #a3 in the logic channel unit. Thus, an optional packet multi plex communication line is connected finely in details.
