GB/T 21645.3-2009 Technical requirements for automatically switched optical network—Part 3:Data communication network
Abstract
This part of GB/T 21645 specifies the architecture and functions of the automatic switching optical network (ASON) data communication network, including data communication network (DCN) applications, general requirements for ASON DCN, management communication network (MCN) requirements, signaling communication network (SCN) requirements, DCN function and structure requirements, and DCN network performance. This part is applicable to the synchronous digital hierarchy (SDH) transmission network defined by ITU-T G.803 and the optical transport network (OTN) defined by ITU-T G.872. DCN applications in other communication networks can also be used for reference.
