Abstract: PURPOSE:To allow the system to easily offer the busy state call service economically by employing a normal incoming and outgoing procedure only to a user network interface in the case of idle state monitor of a called destination, idle notice of a called destination and recall or the like. CONSTITUTION:A caller user 2 sends a signal 1' for call request to an exchange 1. The exchange 1 sends a signal 2' for an incoming call request to a called destination user 3. In the case of making communication with other party 4, the user 3 returns the signal 3' to the exchange 1 because the user 3 cannot reply the incoming request and release a 1st incoming call. Moreover, the exchange 1 receiving the signal 3' sends a signal 4' to inform it to the user 2 that the user 3 cannot reply the call. The user 2 receives the signal 4' and sends a signal 5' to request a callback of the user 3 to the exchange 1 immediately when the user 3 is idle. The call is released with the transmission reception of signals 6', 7'. The communication between the users 2, 3 is established by repeating the processing above.

In this case, output signal 38 of signal 36 having a small pulse cycle shows a higher level of voltage than output signal 39 of signal 37 through the conversion into the DC component since the amplitude is equal between pulses 36 and 37. As a result, it is decided that the input signal of terminal 21 has a higher frequency from the output voltage given from terminal 23 of comparator 9.
