GB/T 16712-2008Characteristics of synchronous digital hierarchy (SDH) equipment functional blocks (English PDF)

What this standard covers

This standard specifies the synchronous digital hierarchy (SDH) equipment functional blocks. Synchronous Digital Hierarchy (SDH) equipment functional blocks shown in Figure 1 the total. In this standard functional definition applies to SDH- user network interface (UNI) and Network Node Interface (NNI). This standard applies to transmission network system equipment, as defined in this standard are not all of the blocks are necessary for each application. You can choose the standard function blocks different subsets, according to the standard rules given in combination, in different ways to provide different combinations of device functions. Network operators and equipment manufacturers can choose to implement some applications to choose which features required. This standard applies to the use of public telecommunication SDH systems, dedicated telecommunications network may also refer to the use of similar systems.
