PURPOSE:To attain a simultaneous command with excellent economy while not requiring any large scale installation and lots of lines by sending the command to plural command receiving extensions accommodated to a command receiving exchange from a command sending extension through the common use of a command sending line. CONSTITUTION:When a command sending side exchange 320 detects a simultaneous command from a command sending extension, the exchange sends a command sending information signal to a command receiving exchange 340. The command receiving exchange 340 receiving the command sending information signal calls a command receiving extension corresponding to command receiving extension identification information included therein. The command transmission from the command sending extension 320 to the command receiving extension 340 is implemented by using the acquired command transmission line to plural command receiving extensions accommodated in the command receiving exchange. Thus, the simultaneous command in a private branch of automatic exchange network comprising plural private branch of automatic exchanges 100,200 connected with each other is implemented with less number of lines and the installation cost is reduced.
