When the cable of the highest priority breaks down, the method of replacing the preference of the cable of the lowest priority

摘要

Traffic of four grades (1 - 4) being the method of transmitting two separate continents (A and B) in 3 these cable telecommunication networks which the terminal are done with four separate landing sights above, when breaking down you can replace the traffic of the lowest grade. With each landing sight the terminal the change logic which decides the route of traffic of the various grades with the change element which it can point the cable and according to breakdown scenario it possesses. The method of installing 3 these cable telecommunication networks, each continent (A and B) the landing sight above (422 and 425) between the 1st cable of bandwidth X (401) the step which lays and, each continent (A and B) the other landing sight above (424 and 427) the 2nd cable of bandwidth X (402) has with the step which lays between. Next, four terminals (422, 424, 425 and 427) it has, the cable where bandwidth is connected 3rd of 2X at least (404, 403, 406 and 405, 403 and 407), is laid between two large overland sights, one terminal, is connected to each landing sight, at least at bandwidth X.
