Abstract

PURPOSE:To detect a trouble concerning connection in a time division channel by assigning a pilot signal corresponding to an (n) multi-frame pattern dislocated by one frame for respective (n) number of incoming highways and outgoing highways, and executing the pilot test. CONSTITUTION:The pilot channel of respective (n) number of incoming highways 19 has an (n) multi-frame constitution, and a pilot signal generated based on an (n) number of multi-frame patterns in which the frame is dislocated for each one frame is respectively inserted. These are outputted to the pilot channel of respective outgoing highways 20 of the same highway number by a time division channel 21. Further, these are respectively collated with a pilot signal for comparison for each highway correspondence to delay the pilot signal only for the delaying due to the time division channel 21. Thus, the trouble concerning the connection between the incoming highway 19 and the outgoing highway 20 can be detected.
