Abstract
A method of selecting information usable by a local unit connected to a digital transmission system includes cyclical scanning at fixed frequency of a list of programmed conditions stored in memory, acquisition of information on the transmission channels and activation of a selection process each time that the selection information of a message has been acquired. The selection process comprises a synchronization stage which waits for the scanning process to cross the start of the list of conditions. In a comparison sequence the selection information is compared with the conditions of the list. A selection variable is produced indicating if the message being received is of interest to the local unit or not. The method may be implemented through the use of a highly integrated interface.
