摘要
介绍了边带通道原理和边带通道保护原理,SDH微波通信系统利用微波帧中RSOH和MSOH预留比特,提供2个双向的2.048Mbit/s容量的边带通道,可在中继站和端站直接提供分/插复用的E1业务,为地处偏僻的微波站提供传输通道。
This paper introduces the principle of both sideband channel and sideband channel protection. By using the reserved bytes of RSOH and MSOH, SDH system can provide two bidirectional sideband channel of 2.048 Mbit/s and add-drop multiplexing E1 traffic between terminal and repeater stations to provide transmission channel, for unattended microwave stations in remote areas.
