The invention relates to a communication system (20) for transmission of signals between pieces of terminal equipment (28) connected to pieces of intermediate equipment (22), connected to a communications network (26) using the Ethernet protocol, said pieces of terminal equipment (28) not being master-controlled by a distributed clock, said pieces of intermediate equipment (22) each including at least one Ethernet access physical interface, at least one interface with a piece of terminal equipment and means for processing the transmitted signals, the communications system (20) including at least one reference clock generator (30). In the communication system according to the invention, a piece of reference time information is periodically transmitted by the reference clock generator (30) and distributed as data transport packets to the pieces of intermediate equipment (22) via the Ethernet access physical interface. Each piece of intermediate equipment (22) includes a local clock generator, said piece of reference time information being received and processed by each piece of intermediate equipment (22), so as to subordinate the local clock generator to the reference clock (30), the means for processing the signals being clocked by the local clock generator so as to obtain synchronous processing of the transmitted signals.
