Abstract

1,134,459. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 16 June, 1967, No. 27786/67. Heading H4K. Auxiliary inter-exchange data links are provided between each pair of exchanges in an inter-exchange system, the data links being used to send particulars relative to P.C.M. speech paths set up or to be set up between the exchanges. The exchanges of the system employ digital switching. The data links may be provided by separate digital paths, by P.C.M. speech paths dedicated to the supervisory data transmission, or by employing spare capacity in the P.C.M. speech paths. The supervisory data may include network channel data to enable alternative inter-exchange routes to be investigated by exchange common controls. The data links may be separated from and mixed with the P.C.M. speech traffic either in the exchange digital switching array or in the inter-exchange junction circuits.
