A METHOD FOR TRANSPARENTLY TRANSMITTING THE MANAGEMENT INFORMATION OF MULTI-MANUFACTURER OPTICAL SYNCHRONOUS DIGITAL HIERACHY DEVICES

摘要

The invention discloses a transparent transmission method for administrative information of SDH devices manufactured by multi-vendors. First, idle overhead bytes of a frame structure of synchronous transfer mode are defined to transfer administrative information of other vendors. At each node of a transmission network, the administrative information is extracted and transformed to a uniform format. After time slot cross, transmission direction of each vendor's administrative information is defined. After format transformation has been implemented again, the administrative information of each vendor is inserted in a frame structure of a designated line. After that, the frame transfers each vendor's administrative information to other nodes, the rest can be deduced by analog, until administrative information of other vendors is transferred to a designated position. With this method, administrative information of SDH devices of multi-vendors can be transparently transmitted over SDH devices of a certain vendor. Moreover, this method is simple and reliable. IMAGE
