Abstract

Procedure, which allows communication between digital terminals (telephones, telefax, etc.), connected to SO (S-Zero) bus, and in which the terminals do not hand the messages over to each other directly, but the messages are sent to the telephone exchange, and the terminals evaluate the reply-messages sent back by the exchange, wherein the random numbers in the element 'TEI-assignment' of the Layer 2 -message according to the ISDN-standardisation represent full messages. As standardised messages are used, no adjustment on the part of the exchange is needed.
