Method and apparatus for telecommunications signal processing and switching

摘要

The establishment of connections between two subscriber or trunk locations or line terminating groups (TG1 . . . TGm) in a communication switching system in which the individual subscriber or trunk locations or line terminating groups are interconnected on a ring-shaped bus arrangement (BUS 0, BUS 1) are carried out through the application of two computers (SB1 . . . SBn) one of which interacts with or serves the calling subscriber location or line terminating group while the second computer interacts with or serves the subscriber location or line terminating group being called. The transmission of communications signals between subscriber locations or line terminating groups occurs through only one of the two computers.
