SSH ETS 300 417-6-1:1998 ed.1

Transmission and Multiplexing (TM); Generic requirements of transport functionality of equipment; Part 6-1: Synchronization layer functions

Scope

This ETS specifies a library of basic Synchronization Distribution (SD) building blocks, referred to as "atomic functions" and a set of rules by which they are combined in order to describe a digital transmission equipment. The library defined in this ETS forms part of the set of libraries defined in ETS 300 417 series. The library comprises the functional building blocks needed to completely specify the generic functional structure of the European digital transmission hierarchy. Equipment that is compliant with this ETS should be describable as an interconnection of a subset of these functional blocks contained within this ETS. The interconnection of these blocks should obey the combination rules given in ETS 300 417. The generic functionality is described in ETS 300 417-1-1 [1].
