METHOD, SYSTEM AND DEVICE FOR TRANSMITTING SYNCHRONOUS DIGITAL HIERARCHY SIGNALS THROUGH MICROWAVE

摘要

In the field of communications, a method, a system and a device for transmitting SDH signals through microwave are disclosed. The method includes: demapping, by a microwave source device, SDH signals received in a microwave frame period to obtain service information, values of positive adjustment states, and values of negative adjustment states, where the service information is asynchronously mapped to the SDH signals by bit by using the values of positive adjustment states and the values of negative adjustment states; generating adjustment frequency information according to the values of positive adjustment states and the values of negative adjustment states; and transmitting the service information obtained through the demapping and the generated adjustment frequency information to a microwave destination device. The microwave source device only transmits the service information and the adjustment frequency information to the microwave destination device, so that long-chain networking transmission can be implemented.
