The telecommunications terminal comprises a remote control structure (AB), with which the terminal is remotely controlled through speech and/or control data. The telecommunications terminal is associated with an interface (SST) with a corresponding interface protocol, which is connected over a network adapter (NA) with a local network (LN) with limited spatial range. The terminal, the remote control structure, the interface, and the network adapter are formed to enable a remote control of an instrument (HAB, WM, EH) contained in the local network, in such way, that a record format (SF) is, especially bidirectional, transmitted, comprising a first part indicating the instrument identification and/or the instrument address, a second part containing a control instruction for the instrument, and a third part containing control usage data.

Description

An arrangement for translating log data into one another units of incompatible networks may be one with interface equipped with considerable intelligence, which the technical term is referred to as "gateway". This interface is based on the OSI reference model (cf. Unterrichtsblätter, vol. 48, 2/1995, pages 102 to 111 and N. Klußmann: Lexicon of communication and information technik, 1997, Hüthig-Verlag, pages 360 to 362) functions of layers 3 or higher (up to layer 7).

The term network includes all resources that are provided by remote service access points and connect them Provide services for communication purposes, ver stood. This strikes both in its extent limited networks, e.g. B. local networks, as well as in their Extension of very large networks, e.g. B. telecommunications networks, to.

Networks that are incompatible with regard to their protocol data units bel are, in particular, telecommunications networks - z. B. the public switched telephone network (PSTN), the integrated services rende digital network (ISDN) based on the asynchronous digital Subscriber line (ADSL) based landline, the mobile radio network according to the GSM standard (first and second cellular genes ration), the mobile network according to the UMTS standard (third month bilfunkgeneration), the mobile network according to the DECT and / or PHS standard, the global computer network (Internet), the electricity supply network and the broadband cable network - and all kinds from local networks - e.g. B. the home automation system, best from a network with one radio, one PLC, one IRDA, an InstaBus, an HES bus, a "twisted pair" or a coaxial cable transmission link.  

The home automation system describes according to the printed document ten "Funkschau 3/1989, pages 45 and 46; electronics 18/1995, Pages 50 to 58; Electronics 17/1996, pages 42 to 47 and Pages 48 to 53; Electronics 4/1997, pages 64 to 72; Elec tronik 1/1998, pages 30 to 33; Electronics 17/1998, pages 74 to 77, pages 78 to 81 and pages 82 to 84 "that "technical management" of houses and apartments. Below everything is understood that the comfort of the residents serves. These include, for example, the load and energy mana gement, water heating, lighting, ventilation heating and heating systems, the operation of motor gears elements (e.g. blinds, garage doors, shutters, etc.) as well as the safety and protective devices (e.g. smoke / Fire alarms, intrusion alarm systems, access monitoring systems gen etc.).

In addition, the "technical management" also controls the control of any other electrical devices - from setting a clock to turning on a coffee machine. When installing home automation systems (home bus systems), the following requirements must be met for a successful market launch:

• 1. No additional cabling
• 2. Low cost
• 3. Uniform communication standard
• 4. Interoperability
• 5. Plug and play capability

In the recent past, various standards for home bus systems have emerged in the field of home automation systems based on different approaches (consumer goods-oriented approach, installation item-oriented approach, computer hardware-oriented approach), which, however, have more or less singular solutions for home Represent automation. These standards include:

• 1. In the consumer goods-oriented approach of consumer electro nics Bus (CEBus), the ESPRIT Home System (EHS) and that Home Bus System (HBS),
• 2. in the installation article-oriented approach of the bati Bus, the European Installation Bus (EIB) and the Smart House and
• 3. Local Ope in the computer hardware-oriented approach rating Network (LON) and The Real Time Operating Sy stem nucleus (TRON)

The question of which of the standards mentioned ultimately changes enforce and thus becomes the de facto standard depends on depend essentially on how attractive the respective standard for home automation. Attractive and really useful However, such a system is only if it is sufficient quantity of products that are communicated via this network adorn. Only if the homeowner bought one Washing machine, an electric stove, etc. knows that the jewei device communicates with its home bus system, it will maybe the additional cost of a home automation system pay and install such a system in his home. If the manufacturer of these devices does not know which one Bus system ultimately makes the "race", this will not oh ne more in an expensive interface for the respective Invest the bus system to find out that the This investment doesn't sell devices better to let.

To the attractiveness of the home car described above Improving mation systems is therefore an "intelligent Home interface "(Residential Gateway) required that on the one hand is inexpensive and on the other hand the manufacturer manufacturer of devices that are remote as part of home automation are controllable, varied possibilities regarding the implementation of the interfaces for the home Automation used bus system offers.

B. in the form a frame structure in the given order.

The first sentence format element STX and the sixth sentence formats lement ETX mark the beginning (STX) and the end (ETX) frame.

The second record format element FRN determines the number of the ak current framework. This number is from the phone TF pro Frame incremented. The remote-controlled device in the loka len network LN is for status messages and spontaneous messages not forced to manage a frame number. But it is stipulate that the frame number should only be specified with a a valid value may be described. Otherwise it is Any initialization with the following exception. At Status info frame that the device to be controlled as a response sends on a status query, the frame number of the ent speaking received frame mirrored, i.e. repeated become.

The third record format element STY gives the action and the Ka or the remote-controlled device. In the higher order Nibble (high-order half byte) is the action - e.g. B. WRite (WR): Process the following date for the corresponding the channel or for the corresponding remote-controlled device; REad (RD): Send the current date of the specified channel or remote-controlled device as a response back to the phone TF; RESPonse (RESP): This action encodes the response to the  o. a. RD action of the device to be controlled remotely on the phone TF; ALARM: Alarm or spontaneous message encodes one spontaneous notification of the device to be controlled remotely to the telephone TF - specified, while in the low-order nibble the channel or the device to be controlled remotely is specified.

The fourth record format element DAT gives z. B. in binary coded Form the date (the payload) for the remote to be controlled Device or channel. The useful information includes e.g. B. the information "switch on device", "switch off device", "Data entry" etc.

The user gives e.g. B. using a maximum of 3 DTMF digits (tones) a decimal value to be transferred. The input will e.g. B. ended with "*" '. First, the 100th digit len, then the 10s and finally the 1- create. After entering the phone TF converts the given number by. Accordingly, the user can do a maximum Enter 3-digit numbers. If he enters fewer digits, so z. B. after a "timeout" no further action tens of the phone TF. Entered values greater than one are predetermined value, z. B. with the specified value encoded.

In the fifth sentence format element CHS, the checksum z. B. calculated on the three preceding bytes "frame number", "record type" and "date". The calculation rule is z. B .:

(Frame number + record type + date) * modulo256

The record format described above is used for a specified remote-controlled device or for a specified Channel to transmit a corresponding date. The meaning the date is z. B. depending on the channel or the fernzu controlling device. So z. B. a specific date at a Channel or for a remote-controlled device to switch on  of the device while the same date is in another channel or other device to be controlled remotely than Actuating value is viewed. The assignment of this meaning is Task of the application in the device to be controlled remotely and is e.g. B. with one exception for the phone TF transparent. The exception is that the BOF command "switch on" with a specified first value and the BOF command "switch off" with a predetermined second value can be encoded.
