Transmission and Multiplexing (TM); Generic Frame Structures for the Transport of Various Signals (Including Asynchronous Transfer Mode (ATM) Cells) at the CCITT Recommendation G.702 Hierarchical Rates of 2 048 kbit/s@ 34 368 kbit/ s and 139 264 kbit/s
This European Telecommunication Standard (ETS) specifies generic frame structures for the transport of various signals at the CCITT Recommendation G.702 [1] hierarchical rates of 2 048 kbit/s@ 34 368 kbit/s and 139 264 kbit/s. The support of Asynchronous Transfer Mode (ATM) cells and Synchronous Digital Hierarchy (SDH) Tributary Units (TUs) in the Plesiochronous Digital Hierarchy (PDH) bit rates is covered in this ETS. Functions specific to the support of ATM cells performed in the transmitter and receiver are not part of this interface standard but are given for information in annex A.
