PURPOSE:To verify the normalcy of the operation state of a conference channel by transmitting a test pattern to the time slot of a speaking subscriber and taking in data from time slots of subscribers, whom he speaks, to compare this data with data resulting from editing. CONSTITUTION:A control part 4 detects unused time slots periodically to transmit information to a test operating part 5 and controls a channel part 3 to set a mimic conference for test. The test operating part 5 transmits the test pattern to idle time slots detected by the control part 4, and the test operating part 5 takes in data, which is edited for the purpose of realizing the conference service by the channel part 3, through a selector 9. The test operating part 5 compares this date with correct data and records the result. |
