The utility model relates to a cross -domain communication transmission circuit - terminating of electric power is to holding route monitoring system, the system includes: gather the circuit data of the cross -domain communication transmission circuit of electric power collection equipment, adaptation machine, data storage equipment, reduction transmission circuit use quick -witted, the application mutual equipment of monitoring is carried out route end -to -end in the transmission circuit, collection equipment the adaptation machine data storage equipment the machine of using it connects gradually to use mutual equipment, collection equipment is connected with the network management system. Connect through carrying out each equipment the combinatorial sum to realize the passway by the reduction, can concentrate at the near -end the routing?information of all nodes of the professional process of cross -domain communication transmission circuit to appear, the user can through use mutual equipment in to the transmission circuit end -to -end route monitor, each is monitored the manpower and materials that result in to the route in regional and extravagant and monitor the defect of inefficiency at the distal end to avoid transporting the dimension personnel.
