适用范围

This European Standard (Telecommunications series) outlines requirements for timing devices called Synchronization Supply Units (SSUs) used in synchronizing network equipment in the Synchronous Digital Hierarchy (SDH) transport network and the Public Switched Telephone Network (PSTN) network. NOTE 1: The requirements in the present document apply under environmental conditions according to one of the environmental classes defined in ETS 300 019 [1], unless stated otherwise. The manufacturer will need to specify to which specific environmental class an equipment belongs.
