Abstract: A safety control device comprises: at least one input module having a number of input interfaces; at least one output module having a number of output interfaces; and a computing unit that includes: a programmable processor; a read-only memory to store an operating program for the processor with program code in machine-readable form for providing a function library with a number of functions of the safety control device; and a non-volatile, overwritable storage medium. A number of function activation codes are stored downloadably in the storage medium, and each of the function activation codes is capable of being assigned a function of the function library such that by logically linking the function activation codes to their associated functions of the function library only those functions of the function library can be activated whose function activation codes are stored in the storage medium.

Abstract: A method and telecommunication system is disclosed for transmission of a message from a first telecommunication terminal to a second telecommunication terminal, of which at least one is connected to a line-connected telephone network. The message is converted as a short message into the short message format, a connection setup is realized and the short message is transmitted in the short message format to a short message service center and from the latter to the second telecommunication terminal, where the transmission of the short message to the short message center and/or to the second telecommunication terminal is carried out by means of DTMF or FSK off-hook signaling in the voice band.

Abstract: The invention relates to a method for the transmission of a message from a first to a second telecommunication terminal (CD), of which at least one is connected to a fixed-line telephone network (PTSN). The message, as a short message, is converted into short message format, a logical connection established by means of an adequately specified data connection layer (DL) and the short message transmitted in short message format, to a short message service centre (SMSC), in an adequately specified physical layer by DTMF or FSK off-hook signalling and then from said centre to the second telecommunication terminal.
