This paper examines the potential of satellite systems to carry synchronous digital hierarchy (SDH) transmissions and proposes a possible earth-station architecture capitalizing on the benefits that SDH equipment offers. It is shown that a range of SDH multiplexing rates are viable over satellite and that multi-destination operation of satellite systems is facilitated by using the inherent features of the SDH. The use of STM-1 (155 Mbit/s) and sub-STM-1 transmission rates as transmission sections along with appropriate integration of the multiplexing and modem equipment would:. (a) enable SDH path continuity between earth-stations, allowing the satellite network to be integrated with managed terrestrial networks to form global managed transmission platforms. (b) provide bandwidth and equipment savings at earth-stations. Several technical issues relating to SDH operation over satellite systems are considered and SDH pointer corruption is examined in some detail. [ABSTRACT FROM AUTHOR] |
