    • The invention herein is fallback function communications device comprised of a microprocessor, utilized to perform a predetermined operation and processing of a predetermined input signal and then output a corresponding signal, as well as a minimum of one relay circuit having an amplifier circuit and a relay. The terminal at the first side of the relay is connected to the telephone line tip/ring terminal, while the terminal at the second side of the relay is connected to the Public Services Telephone Network (PSTN) tip/ring terminal of the microprocessor. An off-hook detection circuit is connected to the PSTN tip/ring terminal and also connected to the ring detection terminal of the said microprocessor. A dummy load circuit is connected to the tip terminal and the ring terminal of the PSTN. As such, in the event of Voice Over Internet Protocol (VOIP) system failure, the present invention is capable of automatically switching to the PSTN and thereby maintain telephone system operation.
    • 本发明是由微处理器构成的回退功能通信装置,用于执行预定的操作和处理预定的输入信号,然后输出对应的信号,以及至少一个具有放大器电路和继电器的继电器电路。 继电器第一侧的端子连接到电话线尖端/环形端子,而继电器第二侧的端子连接到微处理器的公共电话网络(PSTN)尖端/环形端子。 挂机检测电路连接到PSTN耳机/环形终端,并且还连接到所述微处理器的振铃检测终端。 虚拟负载电路连接到PSTN的终端和环形终端。 因此,在因特网协议语音(VOIP)系统故障的情况下,本发明能够自动切换到PSTN,从而维持电话系统的运行。

    • A radio base station is disclosed that monitors faults of radio communication modems based on the content of received frames that are received during call connection. The radio communication modems are mounted in units of prescribed number on signal converters of card structure and are assigned to correspond to mobile stations that perform call connections. The radio base station uses fault detection data to check the content of frames that are received during call connections for each radio communication modem, and counts the total number of received frames and the number of frames in which faults are detected. Upon termination of a call connection, the radio base station determines whether or not a fault has occurred in a radio communication modem based on the counted ratio of the number of frames in which faults are detected to the total number of received frames, and if a fault has occurred, attempts recovery control. If a radio communication modem does not recover, the radio base station deletes the radio communication modem as a candidate for next assignment. The radio base station further transmits, to maintenance personnel through the radio base station controller, a message prompting exchange of a signal conversion card in which the number of faulty radio communication modems reaches or exceeds a particular number.
    • 公开了一种基于在呼叫连接期间接收的接收帧的内容监视无线电通信调制解调器的故障的无线电基站。 无线电通信调制解调器以卡结构的信号转换器安装为规定数量的单位,并被分配给对应于执行呼叫连接的移动台。 无线基站使用故障检测数据来检查在每个无线电通信调制解调器的呼叫连接期间接收到的帧的内容,并且对接收到的帧的总数和检测到故障的帧的数量进行计数。 在呼叫连接终止时,无线基站基于检测到故障的帧数与接收帧的总数的计数比率,判断无线通信调制解调器是否发生故障,如果是 发生故障,尝试恢复控制。 如果无线电通信调制解调器没有恢复,则无线电基站将无线电通信调制解调器删除作为下一个分配的候选者。 无线基站还通过无线基站控制器向维护人员发送提示交换信号转换卡的消息,其中故障无线电通信调制解调器的数量达到或超过特定数量。
