Description

Circuit arrangement for establishing a dial-up connection

Telephone subscribers within a telecommunications, in particular telephone network, who want to set up a certain dial-up connection to a subscriber, his phone number is not known to them, have the option of engaging a central Information center to find out this number. About those from the asking participants The call number established to the central information center is communicated to him, which he can make a note of and then after releasing the first established connection establish the desired connection to the subscriber to be called.

The notification of the desired phone number has always been acoustically so far, because this number is assigned by an information person. You can also do that Fuf numbers stored in a central information center in the form of image information transmitted to the calling subscriber, if this has a corresponding screen or any other visual display option for alpha-numeric characters is. But even in this case, the participant in question must first set up the Trigger connection and establish a new connection to the transmitted through the Establish the subscriber marked with the telephone number.

In order to set up a Wnbl connection for the calling party in these cases To facilitate and accelerate participants, proposes the present invention before that one assigned to the calling subscriber and from the information memory of the optical display adjustable selection device is provided, which upon acknowledgment the visual display by the calling subscriber with the separation of the central one Information center automatically establishes the connection accordingly the phone number called up by the information center and stored at the subscriber's causes.

In the drawing, two embodiments of the invention are in the form represented by two block diagrams.

Fig. 1 shows the structure of a subscriber station with display of the queried Call number through a screen and wig. 2 the structure of a subscriber station, whereby the requested number is displayed on the telephone set itself.

In Fig. 1, the subscriber line Tt, via a modem M, is both on the telephone FA as well as connected to the screen BS. The control of the screen device BS can with the help of a remote control known per se F3 done. The text displayed by the screen is known in each case Way held by appropriate storage devices in the display device BS and if it is a question of dialing information retrieved from the telephone set FA, through the central information point the screen BS in the form of image signals is communicated, this call number can with the help of the dialing device WÄ in one of the Connection system adapted dialing information are implemented that the connection between the telephone set FA and the respective desired subscriber. The screen device BS can also be fully used for other screen text traffic.

In the arrangement shown in FIG. 2, the screen device is ijur for receiving the requested information transmitted by the central information point Call number designed. The telephone set TWA has a keypad that can be used which is necessary for the display and forwarding of the requested phone number Perform switching operations. These switching processes consist in the separation of the first to the central information point established connection, in the input of the display information held in the memory SP in the acknowledgment of the display and the associated input of the stored and displayed selection information into the dialing device WÄ, which automatically sets up the connection to the desired Junction controls. Then the memory SP, the display A u.-ld The WG voting facility is also verified.
