Filed:

Dec 23, 1980

Appl. No.:

6/219547

Inventors:

Nathaniel Simmons - Phoenix AZ
Stig Magnusson - Phoenix AZ
Sergio E. Puccini - Scottsdale AZ
Donald W. McLaughlin - Naperville IL
David J. Stelt - Lombard IL

Assignee:

GTE Automatic Electric Labs Inc. - Northlake IL

International Classification:

H04J 300

US Classification:

370 63

Abstract:

A simplex time-space-time switching network is shown in which there is a crossover of voice information from one rail to another rail in a large digital switching system. The time control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information. These two rails crossover in the originating time switching stage but remain segregated throughout the space switching stage and the terminating time switching stage.

Abstract:

A duplex time-space-time switching network is shown in which there is a crossover of voice information from one rail to another rail in a large digital switching system. The time and control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information. These two rails crossover in the terminating time switching stage but remain segregated throughout the space switching stage and the terminating time switching stage.

International Classification:

H04J 300

US Classification:

370 63

Abstract:

A duplex time-space-time switching network is shown in which there is a multiple crossover of voice information from one rail to another rail in a large digital switching system. The time and control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information. These two rails crossover in the originating and terminating time switching stages but remain segregated throughout the space switching stage.

US Classification:

370 63

Abstract:

A time-space-time switching network is shown in which there is a multiple crossover of voice information from one rail to another rail in a large digital switching system. The time and control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information. These two rails crossover in either or both the originating and terminating time switching stages but remain segregated throughout the space switching stage.
