Systems and methods for handling crosstalk vectoring failures in multi-card vectoring groups

A communication system comprises a plurality of line cards having transceivers coupled to a plurality of subscriber lines. Each line card has at least one active transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by an active transceiver that is a member of the vectoring group. In the event of a vectoring fault that prevents a line card from receiving vectoring information from at least on other line card, the vector logic is configured to disable vectoring for the interferers affected by the error in order to prevent vectoring operations based on obsolete vectoring coefficients from adversely affecting the quality of the communicated signals. The transceivers communicating signals affected by the suspended vectoring operations are also configured to adjust their constellation density profiles, thereby reducing their data rates, to accommodate the increased noise level resulting from the loss of vectoring. By handling the vectoring fault in such manner, communication can continue without requiring a retrain.

Systems and methods selectively excluding tones from vectoring

A discrete multi-tone (DMT) transceiver communicates tones across a subscriber line. Vectoring is employed in an effort to reduce the effects of crosstalk. However, for some tones, such as tones significantly affected by radio frequency interference (RFI) or other forms of alien noise, vectoring may actually introduce distortions such that the vectoring degrades rather than improves overall signal quality. Control logic of the DMT transceiver is configured to sense when tones are affected by significant levels of alien noise and to exclude such tones from vectoring, thereby improving signal quality for such tones. The control logic also may lower the constellation densities of such tones in order to accommodate the vectoring exclusions applied to such tones.

Protection switching device for subscriber's line interface circuits

FIELD: telephone communications. SUBSTANCE: since subscriber's line interface circuits are sensitive to overvoltage often caused by lightning affected subscriber's lines, their operations could be in danger. Overvoltage can be alleviated by means of switching circuits with expensive special-purpose elements and additional circuits. This invention discloses device design in which this is achieved by general-purpose power thyristor, which control electrode voltage or cathode voltage in blocked state or overvoltage in conducting state is compared to reference voltage by means of comparator. If overvoltage is detected subscriber's line interface circuits are switched on when no current runs through control input so that level of blocking thyristor is not reached. Current is supplied again, only if there is no overvoltage in blocked state. EFFECT: decreased cost, possibility of protection of multiple subscriber's line interface circuits. 1 dwg СУСС ПЧ ГЭ РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (19) ВИ” 2124 274 ' (51) МПК 13) Сл Н 04 М 19/02 12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 94028268/09, 04.08.1994 (30) Приоритет: 07.08.1993 ОЕ Р 43 26596.0 (46) Дата публикации: 27.12.1998 (56) Ссылки: ЕР 0247913 ВД, 02.01.89.

Auto-answering service method

본 발명은 착신측 가입자의 교환기 및 단말기의 정상 동작상태를 점검하는 것이다. The present invention is to check the normal operating state of the exchange and the terminal of the called party subscriber. 본 발명은 호처리 블록과 HLR의 사이에 전송되는 정보를 이용하여 자동 응답 서비스 기능를 수행하는 것으로서 자동 응답 번호 정보는 HLR에서 호처리 블록으로 전달되어야 하고, 호처리 프로세서는 발신측 및 착신측의 통화로를 연결한 상태에서 자동 응답 번호가 확인될 경우에 착신측 교환기의 자동 응답 장치음을 통화로를 통해 발신측으로 전달함으로써 착신측 교환기의 정상 동작여부 및 단말기의 이상 여부를 확인할 수 있다. The present invention performs an answering service function by using information transmitted between the call processing block and the HLR. The answering machine number information should be transferred from the HLR to the call processing block, and the call processing processor calls the calling party and the called party. When the answering machine number is confirmed in the connected state, the answering device of the called exchange is transmitted to the calling party through the call path, thereby checking whether the called exchange is in normal operation and whether the terminal is abnormal.

Method of Detecting State of Connection between Switching System and Digital Terminal

본 발명은 교환기 시스템과 디지털 단말기간의 연결상태 감지 방법에 관한 것으로, 특히 원격지에서 운용중인 디지털 단말기에서의 간헐적인 동기비트의 깨짐으로 인한 교환기 시스템과의 연결, 비연결 상태의 식별에 적당하도록 한 교환기 시스템과 디지털 단말기간의 연결상태 감지 방법에 관한 것이다. The present invention relates to a method for detecting a connection state between an exchange system and a digital terminal, and in particular, an exchange that is suitable for connection to an exchange system and identification of a disconnected state due to intermittent synchronization bit breaks in a digital terminal operating remotely. The present invention relates to a method for detecting a connection state between a system and a digital terminal. 본 발명에 의한 교환기 시스템과 디지털 단말기간의 연결 상태 감지 방법에 의하면 동기비트가 변화하더라도 일정한 유지시간 만큼 지속되는 경우에만 동기상태 양호메시지 및 동기상태 깨짐메시지를 교환기 시스템의 호처리부로 보내므로 동기비트 신호의 요동에 의한 불안정한 현상을 막을 수 있으며, 디지털 단말기의 연결/비연결 상태를 명확히 구분하여 교환기 운용을 할 수 있다. According to the method for detecting the connection state between the exchange system and the digital terminal according to the present invention, the synchronization state good message and the synchronization state broken message are sent to the call processing unit of the exchange system only when the synchronization bit changes, but only for a predetermined holding time. It can prevent the unstable phenomenon caused by the fluctuation of the device and operate the exchange by clearly distinguishing the connected / disconnected state of the digital terminal. 또한, 일정 주기의 감지 시그널 태스크마다 전 채널을 감지하므로 동기비트의 신호에 대한 식별을 명확히 할 수 있으며, 초기 구동시 전 채널을 감지하여 디지털 단말기의 연결/비연결 상태 감지가 완료되면 바로 동기양호 카운터/동기깨짐 카운터 값을 증가시킬 수 있게 되어 내선관리부의 부하가 걸리지 않도록 할 수 있다. In addition, all channels are detected for each detection signal task in a certain period, so the identification of the signal of the sync bit can be clarified. When the initial operation is completed, all channels are detected. It is possible to increase the counter / breakdown counter value so that the station manager is not overloaded.
