Architecture of Transport Networks Based on the Synchronous Digital Hierarchy (SDH) - Series G: Transmission Systems and Media Digital Systems and Networks Digital Transmission Systems - Digital Networks - General Aspects Study Group 13
This ITU-T Recommendation describes the functional architecture of transport networks including network synchronization principles for networks that are based on the SDH. This ITU-T Recommendation uses the architectural description defined in ITU-T Recommendation G. 805, the generic functional architecture of transport networks. The application of various mappings is also included.
