Title: Switching controller
Inventor: SUGANO KEIKO
IPC: H04L69/40
Filed: 1994-05-23
Abstract: PURPOSE:To shorten the time up to the end of automatic switching by continuously monitoring the presence/absence of fault generation without performing any other processing until the fault of an active device is detected, and switching the active device to a reserve device just after the generation of any fault is detected. CONSTITUTION:When a control part 32 inside a switching controller 300 detects the fault of a large power amplifier 30-1 while the device 30-1 is connected with an antenna 33 in the initial state, a large power amplifier 30-2 is automatically connected to the antenna 33 by controlling a switch 31. Concerning the presence/absence of the fault generation, the time from a time point t1, when an alarm signal from the device 30-1 is turned on, to a time point t2, when the alarm is recognized, is extremely shortened and the time up to a time point t3, when the switching operation is completed, is shortened to about 150ms. Namely, the switching controller continuously monitors the fault without performing the other processing until the input alarm is changed and when the change of that signal is detected, the switching operation is executed. Therefore, the time from the fault generation to the completion of the switching operation can be shortened and the omission of data can be minimized.
