<p>The invention concerns a method and a system for transmitting Ethernet frames in a SDH network. The adaptation method consists in substituting, to one Ethernet frame transporting IP datagrams or the like, delivered by a local transmitting Ethernet network, a frame consisting of NRZ-type binary data, wherein to the preamble field is substituted a 'particular word' field, the remainder of the frame being unchanged, said 'particular word' being designed to be identified. The restitution method, after an adaptation in accordance with the adaptation method, consists, after identification of the 'particular word' field of the NRZ-type binary data frame, is to restore an Ethernet frame transporting IP datagrams and deliver it to a local Ethernet receiver.</p> |
