Title: Method for in-house voice and data communication through the in-house power supply
Inventor: KLIEM HELMUT
IPC: H04M1/71
Filed: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE           A method for in-house voice and data communication through the  in-house power supply is described.   Two transmission channels having different  frequencies  are used,  and voice transmission is performed by means of frequency modulation of the carrier frequency.  The method according to the invention employs two channels for voice and  data  transmission.    Voice  transmission  is  also performed, by means of frequency modulation.   For data transmission, in particular for transmission of the dial information, a pulse modulation procedure is applied.  The calling party transmits digital telegrams containing the necessary information such as the kind of action, source address and destination address.  The called party responds by an acknowledgement telegram.   Therefore, a hand-shake procedure is employed.  The telegrams are generated in a simple way by switching the carrier frequency on and off. The in-house power supply network represents a bus with two channels, the assignment of which is performed following a predetermined scheme during access to the network.  By this method, a simple structure of a direct connection between two  users  is  possible,  and  an  in-house  communication network can be built up in a simple way.   A central exchange is not required.   Connection of the in-house communication network to the external public telephone network is possible.

Title: Radio telecommunication apparatus having an operation disabling system
IPC: H04M1/00
Filed: 1991-05-30
Abstract: The automobile telephone apparatus comprises the EEPROM, into which a telephone number MIN, and a system identification number SID of a geographical area corresponding thereto are written before shipment. A predetermined operation disabling code is stored in the EEPROM, and the apparatus is disabled while this code is stored therein.  Each of the product apparatus is assigned with its own disabling code.  When the assigned disabling code is input to the CPU from the keyboard, the CPU erase the disabling code stored in the EEPROM, enabling the apparatus to be used.  A purchaser who buys this automobile telephone apparatus informs the service company of the serial number of the apparatus, along with his or her name and address.  When the contract between the company and the user for registration has been completed, the user is informed of the operation disabling code of the purchased apparatus. Upon inputting the disabling code by the user, the prohibition of the operation is released, and therefore, the apparatus becomes ready to be used.
