Abstract
Abstract A telephone answering system with remote control capabilities which responds to a control signal received over the telephone line during an announcement interval (T 1 ) or during a message recording interval (T 2 ) to play back messages over the telephone line to the calling party. The system is susceptible to a number of controlled operations such as the playback of all previously recorded messages, playback of new messages only, remote changing of the announcement, remote backspacing control, selective erasure of the messages after playback, providing an indication to the calling party as to whether any new messages have been recorded since his last remote operation, and other controlled operations to be described.

424 words
In a telephone answering system which responds to telephone messages received over a telephone line and which includes a first magnetic tape mechanism (T-1) having a recorded announcement thereon to be transmitted over the telephone line to a caller during a time interval (T 1 ) in response to a telephone call, and a second magnetic tape mechanism (T-2) for recording messages received over the telephone line during a second time interval (T 2 ) following the time interval (T 1 ), and which responds to a remote control signal received over the telephone line from a caller during the T 1 or T 2 time intervals to effectuate predetermined control operations; the combination of: a microcomputer; circuit means adapted to be coupled to the telephone line for receiving the remote control signal transmitted over the telephone line and for introducing the remote tone to the microcomputer; a beep oscillator circuit connected to the microcomputer to be turned on and off by the microcomputer and being coupled to the telephone line for transmitting beep tone signals over the telephone line and connected to the first magnetic tape mechanism (T-1) for recording said beep tone signals on the T-1 tape mechanism; an input circuit adapted to be coupled to the telephone line for receiving audio signals therefrom; an output circuit for coupling the system to the telephone line for transmitting audio signals to the telephone line; a first circuit connecting the microcomputer to the T-2 tape mechanism to cause the T-2 tape mechanism to move in a forward direction; a second circuit connecting the microcomputer to the T-2 tape mechanism to cause the T-2 tape mechanism to move in a reverse direction; a third circuit connecting the microcomputer to the T-1 tape mechanism to cause the T-1 tape mechanism to move in a forward direction; a fourth circuit connecting the microcomputer to the T-1 tape mechanism to cause the T-1 tape mechanism to move in a reverse direction; said microcomputer responding to the remote control signal received from a caller over the telephone line during the T 2 interval to cause said beep oscillator to transmit at least one beep tone signal over the telephone line to the caller; and said microcomputer responding to the remote tone signal from a caller received over the telephone line during the T 1 interval to cause the third circuit to stop the forward motion of the T-1 tape, and to cause the beep oscillator to transmit at least one beep tone over the telephone line to the caller.
Claim 3
Dependent Claim
143 words
The combination defined in claim 1, in which the microcomputer responds to a remote control signal received over the telephone line from the caller by said circuit means during the time of duration of the beep tone transmitted to the caller over the telephone line to cause the fourth circuit to rewind the T-1 tape mechanism to its beginning position; and subsequently to cause the third circuit to move the T-1 tape mechanism in the forward direction to enable a new announcement received from the caller over the telephone line by the input circuit to be recorded on the T-1 tape mechanism; and the microcomputer causing said beep oscillator to record a beep tone on the T-1 tape mechanism at the termination of the new announcement, and for then causing said third circuit to terminate the forward motion of the T-1 tape mechanism.
Claim 4
Dependent Claim
90 words
The combination defined in claim 2, and which includes circuitry connecting the T-1 tape mechanism to the microcomputer for introducing the beep tone recorded on the T-1 tape to the microcomputer during a T 1 interval to cause the third circuit to stop the forward motion of the T-1 tape, and to cause the first circuit to move the T-2 tape mechanism in the forward direction to enable a message received from a caller over the telephone line by the input circuit to be recorded on the T-2 tape mechanism.
Claim 5
Dependent Claim
90 words
The combination defined in claim 1, in which the microcomputer responds to a remote control signal received over the telephone line from a caller by said circuit means to cause the second circuit to rewind the T-2 tape mechanism a predetermined amount, and then to de-activate the second circuit and activate the first circuit to cause the T-2 tape mechanism to move in a forward direction to cause messages recorded on the T-2 tape mechanism to be transmitted to the caller through the output circuit and over the telephone line.
Claim 6
Dependent Claim
66 words
The combination defined in claim 4, in which the microcomputer activates the beep oscillator after the messages recorded on the T-2 tape mechanism have been transmitted to the caller over the telephone line, to cause the beep oscillator to transmit a beep tone over the telephone line to the caller, and then de-activating the first circuit to stop the forward motion of the T-2 tape mechanism.
Claim 7
Dependent Claim
61 words
The combination defined in claim 5, in which the microcomputer responds to a remote control signal received over the telephone line by said circuit means from the caller during or after said last-named beep tone to activate said second circuit so as to cause the T-2 tape mechanism to drive the T-2 tape in the reverse direction to a predetermined position.
Claim 8
Dependent Claim
40 words
The combination defined in claim 6, and which includes an erase head magnetically coupled to the T-2 tape, and circuitry controlled by said microcomputer for activating said erase head as the T-2 tape is being driven in the reverse direction.
Claim 9
Dependent Claim
66 words
The combination defined in claim 4, in which the microcomputer responds to a remote control signal received from a caller over the telephone line by the circuit means to activate the beep oscillator to cause a beep tone to be transmitted over the telephone line to the caller in the event there are no messages on the T-2 tape mechanism to be transmitted to the caller.
