Abstract: Interconnection system for attaching a maximum number n of equipment users EU (DCE or DTE) to the line adapter 2 of a communication processing unit. The user data and control bits are carried on transmit and receive serial link 4 and 6 in data and control slot entities arranged in frame of period T, comprising one entity per user. These entities are allocated to the user equipments through multiplexing/demultiplexing circuit 10, link adapters 12-1 to 12-8 and connecting boxes 30-1 to 30-8. The user equipments are connected though active remote modules which are specific to the standardized interfaces of the user equipments. Link adapters 12-1 to 12-8 add to the data and control slot entities an outband slot which is used for exchanging control information, such as the active remote module address and type which are stored in memory 42, to be transmitted to the line adapter 2. The advantage of the interconnection system is that the attachment of the user equipments is simplified.
