PURPOSE: A device for testing a channel portion by sensing condition of a communication route is provided to test a channel portion only in case that the communication route is in the idle condition and in order that the data on communication aren't lost by cutting the communication route. CONSTITUTION: A device for testing a channel portion by sensing condition of a communication route includes a terminal portion(11), a control portion(12), an analog testing portion(13), a data testing portion(14), a channel portion(70) of sound range and a channel portion(80) for code range. The terminal portion(11) inputs and monitors the order about controlling and data. The control portion(12) manages the order about controlling and data permitted from the terminal portion(11) and controls each functional portion. The control signals are permitted to the analog testing portion(13) and the data testing portion(14) from the control portion(12). The channel portion(70) of sound range is composed of a signal bit detecting portion, a route condition deciding portion and a route condition latching portion of the sound range. The channel portion(80) for code range is composed of a data sensing portion and a route condition latching portion of the code range. |
