    • A local communication system among ISDN terminal equipment in a user's premises are connected to a local passive bus of the LSDN basic-access interface. The present system can establish the local communication through a network termination unit among ISDN termination equipment. In order to establish such a local communication, a multiframing scheme is taken on a passive bus forming multiframes by combining together the predetermined number of frames which are as defined in the I.400 series of CCITT recommendations. The network termination unit has a switching device for coupling two circuit-switched type communication channels (B1, B2) on the passive bus in one direction of transmission with the two other channels (B2, B1) in the other direction to establish local communication. Alternatively, the switching device couples the two channels on the passive bus with those on the subscribed line to establish external communication. Each of the terminal equipments has a device for requesting the local communication when required.
    • 用户场所的ISDN终端设备之间的本地通信系统连接到LSDN基本接入接口的本地无源总线。 本系统可以通过ISDN终端设备之间的网络终端单元建立本地通信。 为了建立这样的本地通信,通过将在I.400系列CCITT建议中定义的预定数量的帧组合在一起,在形成多帧的无源总线上采取多层次方案。 网络终端单元具有切换装置,用于在另一方向上与一个方向的两个通道(B2,B1)在一个无源总线上耦合两个电路交换型通信信道(B1,B2),以建立本地通信。 或者,开关装置将被动总线上的两个通道与订阅的线路上的两个通道耦合,以建立外部通信。 每个终端设备具有当需要时请求本地通信的设备。

    • The ISDN user-network interface is defined in the CCITT D-channel protocol recommendation (I-400 series recommendations), in which many kinds of communication terminals (e.g. faximile, telephone, teletex, etc.) can communicate through a subscriber line. The user-network interface is improved from the view point of effectiveness of terminal usage, provision of communication service, and, flexibility of system configuration, by providing a control terminal in the subscriber. The control terminal doubles as ordinary terminal equipment, and has a global control function for controlling other subscriber terminal equipment. The control terminal establishes and/or releases a local control phase in which a control terminal controls ordinary terminal equipment in the same subscriber to have them correspond to the communication with another subscriber using the means which belong to the ordinary terminal equipment inherently. The control terminal operates as an ordinary terminal apparatus when it is not in local control phase.
    • ISDN用户网络接口在CCITT D信道协议推荐(I-400系列建议)中定义,其中许多种类的通信终端(例如传真,电话,电信等)可以通过用户线进行通信。 通过在用户中提供控制终端,从终端使用的有效性,提供通信服务以及系统配置的灵活性的角度改进了用户网络接口。 控制终端兼作普通终端设备,具有控制其他用户终端设备的全局控制功能。 控制终端建立和/或释放本地控制阶段,其中控制终端控制同一用户中的普通终端设备使其与其他用户的通信对应,使用属于普通终端设备的装置。 当不在本地控制阶段时,控制终端作为普通终端设备工作。

    • An apparatus for detecting a tone signal in a telephone switching system is provided in which a calculation, in particular, multiplication is performed by a table look-up process in a digital memory, instead of using a conventional complicated multiplier. A tone signal of a particular frequency in a telephone line is detected through a discrete Fourier transform process (DFT), by the calculation of s(i)=x(iT).times.sin(i2.pi.fT), c(i)=x(iT).times.cos(i2.pi.fT), S=.SIGMA.s(i), C=.SIGMA.c(i), and P=S.sup.2 +C.sup.2. In the above calculation, the multiplication (x(iT).times.sin(i2.pi.fT), and x(iT).times.cos(i2.pi.fT)) is performed by a table look up method in a read only memory (ROM). Thus, the calculation is simplified. Further, the ROM has cells for only the discrete particular levels of multiplicands and/or the multipliers to reduce the capacity of the ROM, and the ROM is referred to by the multiplicand and/or the multiplier through the conversion of the same by a coefficient number generator.
