method and apparatus for integration of fast ethernet packets in sonet containers on a radio system

摘要

Described are a method and apparatus for mapping Fast Ethernet data interfaces (in addition to possible data interfaces of different type) into a single VC-4 Virtual Container of a STM-1/OC-3 payload transmtited to a radio-link system. The method is characterized by the steps of: packeting the Fast Ethernet signal and any other signal, mapping the packets into a single (VC-4) Virtual Container of a STM-1/OC-3 payload of a SDH/SONET signal frame, and transmitting said signal frame through the point-to-point radio-link, said radio link being a point-to-point SDH/SONET radio link. All the packets have the same format and are associated to a header for identifying the source. The interfaces of different type are conveniently grouped. Possibly, the VC-4 is filled with null packets to exhaust the maximum available capacity. IMAGE
