Transmission and Multiplexing (TM) - Generic requirements of transport functionality of equipment - Part 2-1: Synchronous Digital Hierarchy (SDH) and Plesiochronous Digital Hierarchy (PDH) physical section layer functions
The present document specifies a library of basic building blocks and a set of rules by which they are combined in order
to describe transport functionality of equipment. The library comprises the functional building blocks needed to
completely specify the generic functional structure of the European transmission hierarchies. Equipment which is
compliant with the present document needs to be describable as an interconnection of a subset of these functional
blocks contained within the present document. The interconnections of these blocks need to obey the combination rules
given. The generic functionality is described in the EN 300 417-1-1 [8].
