This European Telecommunication Standard (ETS) specifies the transmission of MPEG-2 Transport Streams (TS) between two DVB interfaces as defined in EN 50083-9 [7] within Plesiochronous Digital Hierarchy (PDH) networks working at the ITU-T Recommendation G.702 [8] hierarchical bit-rates of 1 544 kbit/s@ 2 048 kbit/s@ 6 312 kbit/s@ 8 448 kbit/s@ 34 368 kbit/s@ 44 736 kbit/s and 139 264 kbit/s. The use of any of these bit rates is optional@ if however one or more rates are selected the complete specification applies. The definition of the network aspects of the transmission of MPEG-2-TSs is based to the maximum extent on existing international and European standards. The equipment considered in this ETS is the Network Adapter performing the adaptation between MPEG-2-TSs and the interfaces of PDH networks.
