DE19537308C2 - Telephone device with hook switch and key - Google Patents

Description

The invention relates to a telephone device Art defined in the preamble of claim 1. Such telephone devices are for example in the DE 28 06 885 A1 and US 4 313 037.

So far, operating the fork switch (GU) a loop interruption in the telephone devices, which corresponds approximately to the duration of the GU operation or the have the time required to securely trigger the connection. In the latter case, this means that the loop window interruption time automatically to a min duration is extended if the GU actuates too short becomes. This automatic minimum interruption time has the Advantage that dialing information is not accidentally sent by GU be generated. When dialing using pulse dialing (IWV) the election information is namely over a sequence of short loop breaks.

For the use of the "new telephone service features" Consultation, brokering, three-party conference, it is necessary a defi during an existing call nated loop break in the order of magnitude 160-930 ms to generate, then the election information for a second connection successfully to the exchange to be able to send. The loop interruption can one can be generated by actuating the GU ("hook flash" in the actual sense of the word), whereby the o. g. automa extension to a minimum interruption time User is helpful here. Comfortable  However, it can also be a specific key (usually the Signal key or inquiry key) if appropriate setting for generating the "hook flash" can be used. The advantage for the user is that the sub break time (flash time) always exactly the required Time corresponds to and like election information also in election save (e.g. one-touch dialing). A ver Visible triggering of the first connection due to too long Actuation of the GU (<930 ms) is when using the corresponding key is therefore also excluded.

It is Z. B. from US 4,313,037 known, a special Flash button connected to two Mul timers tivibrators with times of this magnitude turn. It is also known from DE 28 06 885, in addition to one such "fork pulse timing" in the push button circuit, a second timer as "disconnect timer" with a delay of 1100 ms. A disadvantage of such circuits is the noticeable delay of Loop separation and readiness for a new assignment even if the new services are not used should be men.

The object of the invention is to provide telephone terminals with a key to train such that the customer and the network operator both unnecessary delays and the unintended ones Use of the new telephone service features with the associated occupancy times for unused connection spared.

This task is solved by a telephone device with the in the Kenn Character of claim 1 listed features.

In the following exemplary embodiment, the invention is described with their function and advantages explained in more detail.  

The invention is the loop break duration with GU actuation from the default setting of the flash Time for the key mentioned (e.g. signal key / consultation button). This signal button (also back question key or flash key) is usually under other uses a flash with a fixed default Length or with adjustable length (e.g. for Inquiries within telecommunications systems).

Is the user or manufacturer by default selected flash time for this button now within the Time, also for the "new telephone service feature "Consultation, brokering, three-party conference are needed (160-930 ms), the telephone device responds short GU operation so that a loop interruption is generated for a safe triggering of the connection is required (<970 ms). Is the set flash time among the times for the "new telephone service features" Consultation, brokering, three-party conference be done (160-930 ms), then the telephone reacts with a short GU actuation so that a new line (loop) as short as possible.

The different loop break times of the GU and making the dependency on the preset Flash time can be reduced with the help of software (with processor system stemen) or, if necessary, also be solved in terms of hardware.

The telephone user often has the behavior that he is after a conversation or after an unsuccessful connection construction only briefly taps the GU and immediately afterwards with the choice for a new connection begins. Has a such users now have the option of "new phone service features "inquiry, brokering, triple conferees use renz, so it causes with conventional GU behavior  unintentionally that the existing connection is inactive is held and another connection is established.

When using a telephone device with the described Preventing GU hook flash is possible the signal button for the required flash time (160 up to 930 ms). When using the signal button there is now the possibility to establish a second connection build without triggering the first one. When using the GU an existing connection is triggered safely. A new angel It only takes place after the minimum loop breaks Safe tripping (<970 ms). Here we can the unused connections that existed for too long, still too unwanted connection charges for an accidentally caused caused inactive connection come.

Does the phone user not have the option of "new Telephone service features "inquiry, brokering, tripartite to use the conference, the signal button can be pressed briefly Flash time (<160 ms) can be set. With GU operation can now a new allocation (loop) at short notice (already from <160 ms).

Claims (1)

Telephone terminal with hook switch and button defined telephone service features, wherein the designed as a signal or inquiry key button for one designated as a "flash time" loop interruption time defined duration and the hook switch are assigned to a loop interruption time with the "flash time" exceeds a minimum duration, characterized characterized net that the functions of the key and the hook switch are coupled by a common time regime excluding identical functions.
