る。Figure 2 shows a practical example of non-invention. This figure shows a case where the sending end is parallel and the receiving end is switched. The outputs of the first pilot oscillator 1 and the second pilot oscillator 7 are the outputs of the first pilot oscillator 1 and the second pilot oscillator 7, respectively. 2nd pyro switch episode for To! After passing through r8.9, it is connected to the transmission line by the coupling circuit 2, and in order to monitor the level of the two routes, the hybrid circuit 3 connects the two routes.
branched into two routes. At the receiving end, the reception level of the pyro and g signals received through each transmission path is monitored by the @l pyro, g monitoring circuit 4 and the second pilot monitoring circuit lO.

It is detected by the pyro and g supervisory circuit 4, and the changeover switch 5 switches the signal to receive 1 mt-, and the alarm is transferred to the game game as an intermittent signal of the iG1 pyro and g through the first pyro and g switches and the chi times wlr8. If you want to switch the remote route to the remote station W#, manually turn off the second pyro and switch circuit 9. At the other station, the second pyro and t monitoring circuit IO operates the switch 5 according to the AND information of the second pyro and t disconnected from both the first and second route transmission lines, and performs the receiving end switching. are doing.
