Foreword
This European Telecommunication Standard (ETS) was produced by the Transmission and Multiplexing
(TM) Technical Committee of the European Telecommunications Standards Institute (ETSI) in order to
provide inter-vendor and inter-operator compatibility of SDH equipments.
This ETS has been produced in order to provide inter-vendor and inter-operator compatibility for transport
functionality of equipment.
This ETS consists of 8 parts as follows:
Part 1: "Generic processes and performance" (ETS 300 417-1-1);
Part 2: "SDH and PDH physical section layer functions" (ETS 300 417-2-1);
Part 3: "STM-N regenerator and multiplex section layer functions" (ETS 300 417-3-1);
Part 4: "SDH path layer functions" (ETS 300 417-4-1);
Part 5: "PDH path layer functions" (ETS 300 417-5-1);
