2The calling back when busy that has made things convenient for user's cancellation to apply for.
Operation principle: under stand-by state at ordinary times, the electronic impulse K switch
14,6 pin connect, control switch circuit 2 no powers, this moment, telephone set 6 kept being connected normally with phone house lead in 5, can carry out proper communication.Hear the other side's busy tone after subscriber dialing, illustrate that the other user is just busy, this moment, the user can click T
1Strong is calling back when busy application key, when having pressed T
1Strong back single-chip microcomputer U
198 pin at first export the high level pulse of a 100ms-300ms, control electronic impulse K switch
14,6 pin disconnect 100ms-300ms, single-chip microcomputer U then
187 pin output high level, make circuit turn-ons in the control switch circuit 2, simultaneously single-chip microcomputer U
1The dtmf code of 7 pin output " *, 5,9, # " four numbers, this code signal sends back in the telephone line through amplifying circuit 3, control switch circuit 2 and rectification circuit 1, after signaling is finished, 87 pin output low levels, control switch circuit 2 is closed, make circuit revert to stand-by state, the whole calling back when busy function of hanging up can be finished, and has reduced or remitted the loaded down with trivial details operation of user.When the user need cancel call back on busy service, first off-hook only need click T then
2Key, single-chip microcomputer U at this moment
187 pin output high level, control switch circuit 2 is connected, simultaneously single-chip microcomputer U
17 pin output " #, 5,9, # " four dtmf codes, this code signal is delivered in the phone house lead in through amplifying circuit 3, control switch circuit 2, rectification circuit 1, and 87 pin output low levels after signaling is finished are closed control switch circuit 2, on-hook can be cancelled call back on busy service.Because the telephone key-press signal of the needed input of different calling back when busy of telco switch may be different, the change of these inputs can be passed through single-chip microcomputer U
1Programming change, to adapt to different input requirements.
