Abstract

The invention relates to a circuit arrangement for a telephone station with an answering machine, where the answering machine is automatically connected to the subscriber line after a specific number of ringing tones. The object of the invention is to allow the station subscriber to intercept an incoming message when the answering machine is in operation without de-activating the answering machine, to participate in the call himself if necessary and to record the call. This is achieved in that an earpiece can be connected via an additional repeating coil inserted in the subscriber line and, if required, a microphone can be connected via a matching network, where this connection does not interfere with the function of the answering machine which is connected in order to record the distant message. The inventive concept can be implemented in all answering machines which can be connected to a 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) to an incoming message to hear to connect and, if necessary, to have a mutually directed conversation, the conversation being recorded.

This is achieved in that an additional in the answering machine Transformer is provided whose primary winding, which consists of two identical parts on the one hand via a line adaptation with an internal point of a speech artery and, on the other hand, directly connected to an internal point of the other speech artery is that the secondary winding of the transformer has two first contacts of a button is routed to the first two connection points suitable for connecting a telephone, that the center tap of the primary coil of the transformer and the internal Point one speech artery via a further contact of the button to a second suitable connection points for connecting a microphone is performed.

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. aside from that the result of this circuit arrangement is that with or without switching on the telephone and microphone there is an essentially constant line matching.

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

The figure shows a subscriber line TL with the speech wires away, an indicated call counting device RZ, a telephone station FS, an answering machine AB with the outer connection points c / d and the inner connection points e / f, with a transformer U, a line simulation R / C, the contacts k1, k2, k3, k4 and two hearing protection diodes G1 / G2. There is also a microphone M and. a phone T shown.

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.

Assume that the telephone station FS is busy and the local participants do not want to be disturbed by unimportant calls, however for his part is waiting for an important call, then it is advisable that he the Has the possibility of accepting calls without the telephone station to use, initially as a listener intended for the answering machine switch on incoming information. For this purpose is between the connection points e / f of the recording and transmitting part of the answering machine AB, the series connection of primary winding of a transformer consisting of two identical halves (1, 2, 3) O and a line adaptation (R / C) switched. The secondary winding of the transformer U leads to two contacts k1 / k2, which can be actuated by pressing a button external connection points g / h to which a telephone T can be plugged. Actuated the subscriber at the telephone station e.g. designed as a lockable button Button, then he can use a telephone T connected to the connection points g / h listen in on the information that the remote party is on the recording part of the answering machine just talking.

He can convey the meaning of the message and most importantly the identity of the Recognize callers and, if necessary, by picking up the handset at the telephone station FS establish a normal telephone connection. 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 connected to the connection points i / e of the answering machine is activated. Now there is between the two subscribers a mutually directed speech bond, however, through the recording part of the answering machine is recorded. This microphone can Of course, also for recording messages on the transmission part of the answering machine to be used.

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. In doing so, the line adaptation provided once changed as little as possible.

The two mentioned diodes G1 and G2 are opposite in the usual way Directed as hearing protection parallel to the telephone T.
