Foreword

The standard reference International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) Recommendation G. 707/Y. 1322.2007 "Synchronous Digital Hierarchy (SDH) Network Node Interface, "Section 6.2, 9, and Chapter 11. Writing rules using the relevant provisions of the work of standardization. This standard replaces GB/T 15409-1994 "frame structure for synchronous digital hierarchy signals." This standard GB/T 15409-1994 specific amendments are as follows. ITU-TG. 841 Corrigendum 1.2002 "and type and characteristics of SDH network protection architecture" Corrigendum 1 ITU-TO. 181.2002 Determination of STM-N interfaces error performance equipment

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 SDH is set can be synchronized digital transmission, digital transmission multiplex standardized grading structure and cross-connect for physical Transfer medium transport payload through adaptation. 3.2 Synchronous Transport Module (STM) is a particular information structure, the STM-0, STM-1 basic modules and higher order modules STM-N (N = 16, 64), wherein the specific information structure STM-N by this standard, STM-1 and STM-N rate by the relationship GB/T 14731-2008 requirements. 3.3 It indicates that the network node interface part of the bit stream can be used for telecommunication services. Signaling should be included in the payload. 3.4 Network Node Interface (implements end, multiplexing, cross-connect and switching functions) between. 3.5 For specifying a virtual container with respect to the support frame offset its transport entity frame reference points.
