Communication system with physical interface and communication controller, and method

A communication system (300) comprises interfaces (311-314) at communication channels (361-364, respectively), coupled to a controller (340) by an address bus (320) and multiplexer (380). The interfaces (311-314) receive data cells and provide status signals (e.g., clav) indicating, for example, cel...

Beschreibung
Zusammenfassung:	A communication system (300) comprises interfaces (311-314) at communication channels (361-364, respectively), coupled to a controller (340) by an address bus (320) and multiplexer (380). The interfaces (311-314) receive data cells and provide status signals (e.g., clav) indicating, for example, cell availability, independently from interface addresses (ADDR) being present at the address bus (320). The interfaces (311-314) continuously send the status signals to the multiplexer (380) which receives the interface address (ADDR) at a control input (386) and forwards the status information of the currently addressed interface to the controller (340).
