    • A silent plug includes a switch adapted to be automatically opened when the connector is inserted into the jack and closed when the connector is not inserted into the jack to eliminate electronically generated noise that would otherwise occur when the plug is inserted. The switch has a sliding ring contact for providing the electrical connection between the tip contact and the ground sleeve and providing 360° contact with the ground sleeve via a bridging contact. A spring applies a force in the mating direction to urge the sliding ring contact into the closed position. An actuator facing the jack contacts the front face of the jack when the connector is inserted into the jack in order to urge the sliding ring contact in a direction opposite to the mating direction and against the force applied by the spring.
    • 无声插头包括适于在连接器插入插座时自动打开的开关,并且当连接器未插入插座时闭合,以消除当插头插入时将发生的电子产生的噪声。 开关具有滑环接触件,用于提供尖端触头和接地套筒之间的电连接,并通过桥接触点与接地套筒提供360°接触。 弹簧在配合方向上施加力以促使滑环接触进入关闭位置。 面向千斤顶的致动器在插头插入插座时接触插座的前面,以便在与配合方向相反的方向上推动滑环接触并抵抗由弹簧施加的力。

    • A method and system for automatically setting up a call in a radio telecommunications network. The system includes a first mobile switching center (MSC) servicing and controlling an area where a originating MS is located and a home location register (HLR) associated with the first MSC. The originating MS sends data which includes the selected time and a destination number of a terminating party. Within the HLR is service logic which determines when the selected time has arrived and initiates the call. Upon determining that the originating MS is idle and available, the HLR establishes a voice channel between the first MSC and the originating MS. Additionally, the HLR establishes a voice channel between the terminating party and a second MSC if the terminating party is a mobile station. The system also records a message for delivery at the selected time to the originating party. Additionally, the terminating party may be a telephone in the Public Switched Telephone Network (PSTN).
    • 一种用于在无线电电信网络中自动建立呼叫的方法和系统。 该系统包括:服务和控制发起MS所在区域的第一移动交换中心(MSC)和与第一MSC相关联的归属位置寄存器(HLR)。 始发MS发送包括所选择的时间的数据和终止方的目的地号码。 在HLR内是服务逻辑,其确定所选择的时间何时到达并发起呼叫。 在确定始发MS空闲并且可用时,HLR在第一MSC和始发MS之间建立语音信道。 此外,如果终止方是移动台,则HLR在终端和第二MSC之间建立语音信道。 该系统还将在所选择的时间向发起方记录用于传送的消息。 此外,终端方可以是公共交换电话网(PSTN)中的电话。
