And after receiving the detection result, the controller sends an off-hook instruction to the automatic off-hook circuit. And after receiving the off-hook instruction, the automatic off-hook circuit executes off-hook operation so as to enable the tested telephone to be in a connected state. And meanwhile, the controller sends sending indication information to the talk test signal transceiver. And after receiving the sending indication information, the call testing signal transceiver sends corresponding call testing information (such as DTMF signals) to the central station through a telephone line connected by the automatic off-hook circuit. After the telephone testing signal transceiver sends the telephone testing information, the automatic off-hook circuit executes an on-hook operation so as to enable the tested telephone to be in an on-hook state.
