Abstract

PURPOSE:To grasp the operating condition of the whole switching network by continuing-executing the supervision of a packet switching network by means of plural exchanges instead of a network supervising center at the time of the trouble of the network supervising center. CONSTITUTION:When a network supervising center 1 is made into the trouble, the transmissions and receptions of logic bus signal lines 12-14 are made impossible. A starting command is inputted from a keyboard display 17 of an acting exchange (example: 3) for the center 1, logical bus signal lines 15 and 16 are set to other exchanges 2 and 4, and thereafter, the exchange 3 is made into a master exchange. The exchanges 2 and 4 are made into slave exchanges, respectively, and the commands can be transmitted through the signal lines 15 and 16. The slave exchanges 2 and 4 transmit communication information from the master exchange 3 and protocol exchanges 5-8 and response information to the command from the master exchange 3 through signal lines 15 and 16 to the master exchange 3. The master exchange 3 displays the command response information and communication information from the slave exchanges 2 and 4 on a display 17, accumulates account information in an external storage device 18, acts for the center 1, and executes the network supervision of the whole packet switching network.
