Abstract
A line-adapter of a communications controller includes, for scanning the teleprocessing lines connected to it, cyclic scanning means FES exchanging information with the lines through a serial bidirectional link on which data and control informations are partitioned into frames and slots. Since both the FES and the serial link work with their own timings, an interface FESA is provided to adapt the FES scanning to the serial link structure. This FESA includes temporary storage means for storing on the one hand, data and control information transmitted from the LICs to the FES (10) through the inbound serial link, and on the other hand, data and control information transmitted from the FES to the LICs through the outbound serial link. The access of the FES, the outbound and inbound serial link to the storage means is time-shared and granted by an arbitration logic, according to the relative priorities of operation of said elements within the line-adapter of the communications controller.
