Abstract
In the telecommunication transport network, network management provided by a manufacture is only capable of managing a zone formed by equipment of the manufacture. However an operation management department needs to operate on a management interface in a management center to quickly establish a passageway across a plurality of zones respectively provided by different manufactures, at the moment the operation department can only inform maintenance crews in each zone to operate one section of the passageway built by the network management provided by different companies, and then each border endpoint of the zones are informed to connect each section of the passageway manually at distributing frames. By means of the transmission resource scheduling system covering the whole transport network, dedicated cross-linking equipment (4, 5, 6) are arranged between borders of every two zones. Passageways are opened in each zone and run through the zone, and the passageways are connected to an interface of dedicated cross-linking equipment. The passageways in each zone can be communicated by only operating the cross-linking equipment on the management interface in the control center, and thereby a passageway which runs through the whole network and crosses each zone is established quickly. Massive investment and construction are not necessary, and fast scheduling is achieved.
