Network architecture and equipment functional aspects of digital satellite systems in the fixed-satellite service forming part of synchronous digital hierarchy transport networks
This Recommendation addresses network architecture and equipment functions relevant for the design of synchronous digital satellite systems in the FSS forming parts of, or providing syhcronous interconnections between, transport networks based on the SDH. A general architectural diagram of FSS systems with SDH network transport capability is introduced. The basic requirement is transparent transport of SDH signal elements (referred to as virtual containers) through the satellite system. This Recommendation focuses on SDH functionalities in the satellite system synchronous baseband equipment (SBE) necessary to realize three different scenarios for satellite system integration in SDH transport networks.
