Abstract
Abstract Digital signal transmission system for communicating devices for switching, controlling, measuring and/or monitoring, particularly for domestic application. The signal transmission system exhibits a basic installation in the form of an interconnected line network, for example in tree structure, each line end of which is terminated by a universal interface which is capable of generating and transmitting or, respectively, receiving and evaluating a signal message. The basic installation provides the possibility of orderly signal message traffic which can communicate with all other universal interfaces. The basic installation can be supplemented by modular device adaptors by means of which the device functions contained in the respective messages can be picked up. <IMAGE>

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
A digital signal transmission system for terminal units communicating with each other, for switching, controlling, regulating, measuring and/or monitoring, in particular for use in in-house information distribution network technology, using subscriber stations interconnected via a combined line network (BLV) and each having an interface for connecting a terminal unit, so as to generate and transmit or receive and evaluate a signal telegram, to process incoming instructions or convert them into analog or digital values, each interface being able to perform signal telegram communication with all other interfaces, characterised in that said interfaces are function-independent universal interfaces (UI) which form a part of the basic installation together with said combined line network (BLV) and that said universal interfaces may be complemented by external function-determining apparatus adaptors (GA) that do not form part of said basic installation.
Claim 2
Dependent Claim
49 words
The signal transmission system of claim 1, characterised in that said apparatus adaptor (GA) is adapted to the respective terminal unit (switching device, control device, regulating device, measuring device, monitoring device) and converts the signals provided by said terminal unit to a form understandable to said universal interface (UI).
Claim 3
Dependent Claim
29 words
The signal transmission system of claim 1 or 2, characterised in that said apparatus adaptor (GA) decodes the incoming telegrams so that a respective terminal unit understands the same.
Claim 4
Dependent Claim
55 words
The signal transmission system of one of claims 1 to 3, characterised in that said apparatus adaptor (GA) includes a converter converting the signals provided by said terminal unit to a form understandable to said universal interface (UI) and a further converter converting the incoming telegrams to a form understandable to a respective terminal unit.
Claim 5
Dependent Claim
27 words
The signal transmission system of one of claims 1 to 4, characterised in that said apparatus adaptor (GA) includes a plug contact (5) for a terminal unit.
Claim 6
Dependent Claim
30 words
The signal transmission system of one of claims 1 to 5, characterised in that said universal interface (UI) includes an address field (2, 3) for setting source and target addresses.
Claim 7
Dependent Claim
42 words
The signal transmission system of one of claims 1 to 6, characterised in that said universal interface (UI) includes an auxiliary terminal (4) via which telegrams generated externally, e. g. by a terminal unit, are fed directly into the combined line network.
Claim 8
Dependent Claim
28 words
The signal transmission system of claim 7, characterised in that telegrams are transmitted via said auxiliary terminal (4) that are evaluated or generated directly by said terminal unit.
Claim 9
Dependent Claim
23 words
The signal transmission system of one of claims 1 to 8, characterised in that said basic installation includes a central power supply (ZSV).
Claim 10
Dependent Claim
31 words
The signal transmission system of one of claims 1 to 9, characterised in that said apparatus adaptor (GA) is detachably connected to said universal interface by electrical and mechanical connecting means.
Claim 11
Dependent Claim
25 words
The signal transmission system of one of claims 1 to 10, characterised in that said apparatus adaptor (GA) and said terminal unit form an assembly.
Claim 12
Dependent Claim
23 words
The signal transmission system of claim 11, characterised in that the terminal unit of said assembly is a command means (switch or key).
Claim 13
Dependent Claim
20 words
The signal transmission system of claim 11, characterised in that the terminal unit of said assembly is a display unit.
