Abstract: A method for forming a semiconductor structure comprising a silicon-on-insulator layer structure with crystalline silicon oxide SiOx as the insulator material comprises: providing a crystalline silicon substrate having a substantially clean deposition surface in a vacuum chamber; heating the silicon substrate to an oxidation temperature To in the range of 550 to 1200 ° C.; supplying, while keeping the silicon substrate in the oxidation temperature, with an oxidation pressure Po in the range of 1·10?8 to 1·10?4 mbar in the vacuum chamber, molecular oxygen O2 into the vacuum chamber with an oxygen dose Do in the range of 0.1 to 1000 Langmuir; whereby a crystalline silicon oxide layer with a thickness of at least two molecular layers is formed within the silicon substrate, between a crystalline silicon base layer and a crystalline silicon top layer. Related semiconductor structures are described.

Abstract: In a telecommunications system, in which a connection comprises a part with an interworking function at both ends, a channel is allocated to the connection between the interworking functions. The required channel capabilities may vary during the connection, whereby the channel capabilities should be changed. When the first interworking function detects that a channel capability must be changed, a first message, which indicates the desired capability change, is transmitted (2-1) to the second interworking function; and the channel capability is changed (2-3,2-5) into the desired one at both ends of the part.

Abstract: The invention provides a method, system, terminal, server, and computer program product for providing or programming a call response function, preferably a voice mail function, in a communication network which includes a call response server having a storing means. The method, terminal, system, and computer program product comprise the steps of preparing or providing, in the terminal, a programming media message, such as an MMS message, which includes response content, preferably audio content. This programming media message is transmitted from the terminal to the call response server which stores the response content of the media message. When a call or session request of another terminal directed to the terminal is forwarded to the call response server the response content is played or transmitted to the another terminal.

Abstract: A method for implementing switching in the time or space domain, in which the switching is effected on the basis of switching data contained in an address control memory, and a basic switching block is defined on the basis of an incoming frame structure so that the number of its time slots corresponds to the greatest possible number of signals of the lowest level of hierarchy to be switched in the frame. The basic switching block recurs in the same form with respect to switching.

Abstract: A method for implementing time switching, and to a time switch. The contents of the time slots of an incoming signal are written into a memory at a memory location determined by a write address and read from said memory at the memory locations indicated by the switching data contained in an address control memory. With the aim of simplifying known solutions, the switching data of each time slot is given as a relative address which indicates the location difference within the frame structure between an outgoing time slot and an incoming time slot to be connected thereto.

Abstract: A time switch and a method for implementing time switching for signals of several different levels of hierarchy. The signals having a common frame structure which can be divided into blocks of different sizes, the blocks being switched differently from one another. According to the method, the contents of the time slots of an incoming signal are written into a memory, from which they are read at the memory locations indicated by switching data contained in an address control memory. In order that the time switching can be implemented in a more simplified manner than before, the contents of all time slots of a frame are continuously written into one memory block without synchronizing the writing with the frame.
