Title:
DISTRIBUTION CONTROL EXCHANGE NETWORK WITH RESPECT TO MULTIPLEX LINE TELEPHONE COMMUNICATION
Document Type and Number:
Japanese Patent JP3605121
Kind Code:
B2
Abstract:
PURPOSE: To attain mutual connection at a position at an addressable designation by receiving and processing a destination logic address code and selecting a proper switch port to designate a data path toward an address corresponding to the code.
CONSTITUTION: To three access switches(AS) 24, 14-sets of I/F switch I/FS 22 of a terminal unit 20 are connected, and the three AS24 are coupled with four different sets in 6 switch planes 30. Furthermore, 19 select switches 26 on the planes 30 are coupled with two of the three AS 24, to connect each plane to 95 sets of units 20. Furthermore, 9 reflection switches 28 of each plane 30 are connected to other switches 26 for allowing each independent processor to control each switch element. Thus, each processor decodes a destination logic address code from a system center 15 to allow each switch element to attain mutual connection at an address designation position by each switch element.
