Abstract

The present invention relates to semi-custom circuit and method to introduce a frame compounded by a certain number of order wires, in a PCM signal flow, wherein signal are multiplex signals as envisaged in the second and third USA level. Each order wire has a transmission capacity of ca. 64 Kb/s, said capacity value depending on the capacity of very multiplex signal flow.The present method can be implemented keeping the order wire frame and multiplex PCM flow completely independent; moreover the frame of the order wire and 64 KB/s PCM Codec - used either according USA standards or European level standards - can be provided with direct interface.
