Abstract

1431992 Automatic exchange systems HASLER AG SIEMENS-ALBIS AG and STANDARD TELEPHON UND RADIO AG 4 April 1973 [4 April 1972] 16142/73 Heading H4K In the exchange system of Specification 1,428,459 it is arranged for every highway to include a channel used for controlling one of the system blocks so that error free transmission of messages between the central control and the blocks can be taken as an indication of the operability of the highways. Signalling on the control channels utilizes acknowledgement messages and the return of an acknowledgement indicating an error, or the failure of an acknowledgement to be received by the central control results in a new control path being set up to the particular block.
