摘要： The invention relates to implementing switching in a switch in a digital telecommunications system. N incoming signals are introduced to the switch, each comprising successive one-bit time slots that form successive frames each comprising K time slots. The contents of the time slots for the incoming signals are stored in a memory at a memory location determined by a write address in such a way that a word having the width of at least one bit is stored at one memory location. One word at a time is read out from the memory, wherefrom the desired bit is selected for the outbound signal from the switch. To optimize the size and power consumption of the switch, the incoming signals are distributed to X multiplexers (A1...Ax), each interleaving the incoming signals thereto into a single serial output signal (IN1...INX), and writing into memory is carried out by writing the contents of the time slots of the output signals into the same memory location having a width of at least X bits, the memory location changing from one time slot of the output signals of the multiplexers to another.

摘要： The present invention relates to a method and device for symmetrizing a clock signal. The leading or trailing edge of each pulse of the clock signal (Fin) to be symmetrized is used for forming the first edge of the pulse of the corresponding symmetrized clock signal (Fout). The pulse ratio of the symmetrized clock signal is measured; and on the basis of the measured pulse ratio, the time constant circuit (R1, C1), determining the location of the second edge of the pulse of the symmetrized clock signal, is adjusted by means of a control loop (R6, C2, A) in such a manner that the second edge of the pulse of the symmetrized clock signal (Fout) settles in a desired position in the symmetrized clock signal.

摘要： The invention relates to a method of locking a clock signal (FOUT) phase adaptively to the phase of different reference signals (FIN) and to a phase lock implementing the method. According to the invention, the frequency of an input reference signal is determined by measuring and the determined reference signal (FIN) is converted by dividing to a signal (FDIN), the frequency of which is some integer multiple of the frequency of the clock signal (FOUT) to be phase locked, or the frequency of the clock signal to be phase locked divided by some integer. The signal (FDIN) and the clock singal (FOUT) to be phase locked or a signal (FD) proportional thereto are used as reference signals of a phase comparator (2) for locking the clock signal phase in a manner known per se.

摘要： The present invention relates to detecting speech channel back-looping in a speech processing device in digital telecommunication systems. The detection is based on the speech samples from different transmitters being independent of one another and random, whereby they can be utilized in the identification of the sender thereof. For the identification, a check value is calculated on the basis of speech samples to be sent (52). The check value is stored at the transmitting end (56). A check value is calculated for the speech samples received from the speech channel (59) in the same way as for the ones sent (55). If the check values match, the conclusion is that the received information is the same as the sent information, i.e. the speech channel is back-looped to the sender. If the check values do not match, the speech information is concluded to have been sent by another party, and the process continues accordingly.

摘要： The invention relates to a method of generating a carrier wave of common channels and a radio system. The radio system comprises a network part, subscriber terminals (110) and a bidirectional transmission path (120) between the network part and the subscriber terminal (110). The bidirectional transmission path (120) consists of frames to be transmitted at a carrier wave frequency. A frame comprises time slots. To a time slot is applied a channel, the channel being either a common channel (FCCH, SCH, BCCH, CCCH) or a dedicated channel (TCH). The carrier wave is generated by ajusting transmission powers of time slots and by using frequency hopping to the effect that first is transmitted at least one time slot containing a common channel (FCCH, SCH, BCCH, CCCH), with a predetermined reference power. Then are transmitted other time slots with a transmission power lower than the reference power, and using frequency hopping. In accordance with the invention at least one other time slot determined by the transmission power sequence is transmitted with the reference power, using frequency hopping.
