Abstract

The invention relates to a switching device for connecting an answering machine to a telephone station. If, for example, the subscriber of the telephone station does not wish to be disturbed, the telephone station is de-activated by a ring counter when, for example, the handset is not picked up, and the answering machine is activated along with an ancillary device. According to the invention, the subscriber of the telephone station can press a button while the distant subscriber is being recorded on the audio tape in the answering machine, whereby a telephone in the ancillary device is activated for listening in when matched to the line. Through a different type of actuation, he can also activate a microphone and thus make a call which is recorded onto the tape. This device is conceivable for any normal telephone station.

Description

Circuit arrangement for a telephone station with call

answerer.

The invention relates to a circuit arrangement for a telephone station with answering machine, with the telephone station in the idle state via its call facility is connected to the voice wires of the subscriber line, and also calls Receiving answering machine counting incoming calls and with the Call counting device connected to speech cores according to a determinable number of calls and at Failure to operate the telephone station switches off the telephone station and switches the answering machine on to the speech wires.

Such circuit arrangements are used for incoming calls automatically to the calling subscriber at an unoccupied subscriber station to send a message after a certain number of calls and they give each after expansion, the calling subscriber has the option of leaving a message. These facilities do not only take effect when the called telephone station is actually unoccupied, but the answering machine is also switched on if the operator at the called subscriber station does not have time to take the call or if she only wants to take certain important calls, for example.

The object of the invention should therefore consist in the person receiving the call to give the opportunity to log in without switching off the answering machine (e.g. without Picking up the handset) for an incoming message to listen to to connect and, if necessary, to conduct a mutually directed conversation, whereby the conversation is recorded.

This is achieved in that, in addition, via first latchable Contacts can be connected to a winding consisting of two parts on the primary side of one Transformer and in series with it a line adaptation between the connection points the answering machine is arranged that still a telephone on the secondary winding of the transformer is switched on and that a microphone can be switched on via second contacts between the center tap of the primary winding in one voice artery and the other Speech vein is arranged.

This has the advantage that the operator of the telephone station with answering machine for an incoming, forwarded to the answering machine Call without operating the intercom station first of all incoming messages from the remote station Participant can overhear to check their importance and that they can be heard if necessary can also report himself, whereby this reporting is also recorded.

The circuit arrangement according to the invention is explained with reference to a figure.

The figure shows a subscriber line TL with the speech cores a / b, an indicated call counting device RZ, a telephone station FS, an answering machine AB with the connection points c / d and an additional device ZE with a microphone M, a telephone T, a transformer Ü, a line simulation R / C, the contacts k1, k2, k3, k4 and two hearing protection diodes G1 / G2.

The function of the circuit arrangement is described below with reference to the figure explained.

It is assumed that a call from a subscriber line TL remote subscriber is present. This call comes through the in rest position Contacts of the call counting device RZ on the call device (alarm clock) of the telephone station FS and there the call desired by the remote subscriber can be opened by picking up the Handset or pressing a handsfree button.

If the telephone station FS is not busy, then one takes place a certain number of ring tones registered by the call counting device RZ Switching the subscriber line TL from the telephone station FS to an answering machine AB, which is then put into operation. The participant loop is via the Answering machine closed and from a tape or from a voice mailbox a message is sent to the remote subscriber. After finishing this message the remote subscriber can now be asked to speak a message for his part, which is recorded by the recording part of the answering machine AB. This stands for usually a predicted specific period of time is available.

If it is assumed that the telephone station FS is busy, that one there Participant does not want to be disturbed by unimportant calls, but on his part is waiting for an important call, then it is advisable that he have the opportunity has to operate the telephone station in the sense of accepting calls, initially as a listener in an incoming message intended for the answering machine Switch on information. To that end is parallel to the answering machine AB (connection points c / d) an additional device ZE is connected. This additional device ZE is assigned a lockable key which, when actuated, uses its contacts kl / k2 parallel to the answering machine AB in series the primary side (1,2,3) of a transmitter U and a line adapter (parallel connection of R / C) switches on. About a from the secondary winding (4, 5) of the transformer Ü and a telephone T existing Nörkreis, the subscriber of the telephone station FS can now record the distant Listen to the participant and recognize their identity and the meaning of the message. If he then wants to speak to the remote subscriber over a normal telephone connection, then he can establish this connection by picking up the handset. The answering machine is switched off.

But he wants it because of the special importance of entertainment, for example have the conversation recorded, then all he has to do is press the button and lock it E.g. turn button. So that two more contacts k3 and k4 are actuated, whereby a microphone M between the center tap (2) of the primary side of the transformer Ü and the circuit output (k2) can be switched. Now there is between the two Telephone subscribers a two-way voice connection, which, however, through the recording part of the answering machine is recorded.

From the foregoing it can be seen that with the aid of the invention Circuit arrangement is possible in a simple manner at a telephone station with Answering machine without picking up the handset an incoming for the purpose of recording Listen to the message and, if necessary, use the answering machine's recording device establish a voice connection.

The two mentioned diodes C1 and G2 are in the usual way as Hearing protection parallel to the phone T.
