    • A remote control system for controlling electrical apparatus in customer premises includes a home control interface for connection by way of network termination equipment, e.g., a telephone socket, to a communications line to a telephone exchange. The home control interface is responsive to signals received from a home control platform connected to the telephone network to control electrical apparatus by way of module interfaces. The home control interface is arranged on demand to transmit signals to the communications line indicative of the current status of each piece of electrical apparatus connected to the system. The consumer may use a telephone to pre-record a definition of the electrical apparatus attached to each connection on the module interface which, when remote control requests are forwarded to the home control platform are used to define the respective switch and to announce its status to the caller. The home control platform has capability of storing substantial quantities of data defining changes required in switching at different times.
    • 用于控制客户住宅中的电气设备的遥控系统包括用于通过诸如电话插座的网络终端设备连接到通往电话交换机的通信线路的家庭控制接口。 家庭控制接口响应从连接到电话网络的家庭控制平台接收的信号,以通过模块接口来控制电气设备。 家庭控制接口根据需要进行布置,以将信号发送到指示连接到系统的每个电气设备的当前状态的通信线路。 消费者可以使用电话预先记录在模块接口上连接到每个连接的电气设备的定义,当将远程控制请求转发到家庭控制平台用于定义相应的交换机并将其状态通知给 来电者 家庭控制平台具有存储大量数据的能力,定义在不同时间切换所需的更改。

    • A switching system for inclusion in domestic premises includes a master socket for connection to network termination equipment (e.g., wall socket) and for connection to a plurality of slave sockets each of which may be connected to normal communications apparatus such as telephone, fax or answering machines not shown. On receipt of an incoming telephone call from the network the master socket uses signals which identify the source of the call (calling line identity (CLI)) signals to determine which of the slaves is to be called. Using only four wires (i.e., the normal extension wiring pattern) the master socket can signal individual slave sockets to switch in or out of circuit so that a normal domestic telephony arrangement may be simply and economically converted to include switching. Various protective options and alternative calling patterns in event of non-answer can also be provided by the master socket including options for allowing communication between two individual extensions without utilizing the main exchange line system.
    • 用于包含在家庭住宅中的交换系统包括用于连接到网络终端设备(例如,壁式插座)的主插座和用于连接到多个从插座的主插座,每个从插座可以连接到通常的通信设备,例如电话,传真或应答 机器未显示。 在从网络接收到来电电话时,主套接字使用标识呼叫源(呼叫线路标识(CLI))信号的信号来确定要呼叫哪个从设备。 主插座只能使用四根导线(即普通扩展布线图案)来发信号通知各个从插座以切换或切换电路,从而可以简单且经济地转换正常的本地电话装置以包括切换。 主机套接字还可以提供各种保护选项和非答案的替代呼叫模式,包括用于允许两个单独扩展之间的通信的选项,而不使用主交换线路系统。
