    • An automatic call-back device notifies a subscriber when a called party's telephone station is no longer busy. When the subscriber calls a called party and the called party's telephone station is busy, the automatic call-back device offers the subscriber call-back options for calling the subscriber when the called party's telephone station is no longer busy. If selected, the automatic call-back device monitors the called party's telephone station for an on-hook signal, for example. When the called party goes on-hook, the automatic call-back device calls the called party and the subscriber and connects the subscriber and the called party in a call. If multiple subscribers call the same called party, the automatic call-back device stores an identifier corresponding to each subscriber in a call-back list based on when each subscriber called the called party. When the called party goes on-hook, the automatic call-back device contacts the first subscriber in the call-back list (i.e., the subscriber that called first). If this subscriber cannot be reached, then the automatic call-back device calls the next subscriber in the call-back list and so on until one of the calling subscribers is connected with the called party or the call-back list is exhausted.
    • 当被叫方的电话站不再忙时,自动回叫设备通知用户。 当用户呼叫被叫方并且被叫方的电话台忙时,当被叫方的电话站不再忙时,自动回叫设备提供用于呼叫用户的用户回叫选项。 如果选择,则自动回叫设备例如监视被叫方的电话机的挂机信号。 当被叫方挂机时,自动回叫设备呼叫被叫方和用户,并在呼叫中连接用户和被叫方。 如果多个用户呼叫相同的被叫方,则自动回叫设备基于每个用户何时呼叫被叫方,将与每个用户对应的标识符存储在回叫列表中。 当被叫方挂机时,自动回叫设备与回叫列表中的第一个用户(即第一个被叫的用户)联系。 如果该用户无法到达,则自动回叫设备呼叫回叫列表中的下一个订户,等等,直到其中一个主叫用户与被叫方连接,或者回叫列表用尽。

    • A system and method of using one-way or two-way paging to establish communications with a mobile party and sensing duplicate pages. A one-way or two-way paging device operates to compare an incoming page with pages that have been received within a predetermined, and preferably subscriber adjustable, time interval. If the incoming page is determined as being identical to a page received and stored by the pager within the preceding predetermined time interval, then the incoming page is deemed a duplicate page, and is therefore disregarded. If the incoming page is determined as not being identical to any pages received within the predetermined time interval, then the page is deemed a new page, which is stored by the pager for comparison to any pages subsequently received within the predetermined time interval, and the paging device notifies the subscriber of the new page. In another embodiment, when a page is sent out to a two-way paging device by the paging system, the paging system updates a database which contains paging information for pages sent out to each subscriber. A two-way paging device that identifies an apparent duplicate page sends a reverse page query to the paging system, requesting confirmation as to the invalidity of the apparent duplicate page. The reverse page includes information that identifies the apparent duplicate page, and the paging system compares this information with that stored in the database to determine whether two separate pages matching the apparent duplicate page were transmitted by the paging system.
    • 使用单向或双向寻呼与移动方建立通信并感测重复页面的系统和方法。 单向或双向寻呼设备操作以将输入页面与在预定的,优选地用户可调整的时间间隔内已经接收到的页面进行比较。 如果传入页面被确定为与在前一预定时间间隔内由寻呼机接收和存储的页面相同,则传入页面被认为是重复页面,因此被忽略。 如果传入页面被确定为与在预定时间间隔内接收到的任何页面不相同,则页面被认为是新页面,其由寻呼机存储以便与在预定时间间隔内随后接收的任何页面进行比较,并且 寻呼设备通知用户新页面。 在另一个实施例中,当通过寻呼系统将页面发送到双向寻呼设备时,寻呼系统更新包含发送给每个用户的页面的寻呼信息的数据库。 标识明显重复页面的双向寻呼设备向寻呼系统发送反向页面查询,请求对明显重复页面的无效的确认。 反向页面包括识别明显重复页面的信息,并且寻呼系统将该信息与存储在数据库中的信息进行比较,以确定寻呼系统是否发送与明显重复页面匹配的两个单独的页面。

    • A method and an apparatus for establishing a local area network (LAN) using a channel stripper, a LAN controller and a cable television cable that couples peripheral devices to the LAN controller. The channel stripper removes signals from one or more selected channels from a cable television signal path. The channels form a signal path between the LAN controller and peripheral devices connected to the LAN. The remaining channels provide a digital cable television signal. Both the LAN channels and the digital cable television channels are combined onto a common coaxial cable. The cable stripper may be a multiplexer/demultiplexer or a notch filter. Alternately, the channel stripper can assign frequency channels outside the frequency bandwidth of to the LAN and maintain the cable television signals as received. The LAN controller can create additional communications channels by using Time Division Multiple Access protocols to assign time slots to each of the peripheral devices that are coupled to the LAN.
    • 一种使用信道剥离器,LAN控制器和将外围设备耦合到LAN控制器的有线电视电缆来建立局域网(LAN)的方法和装置。 信道剥离器从有线电视信号路径去除来自一个或多个所选信道的信号。 通道形成LAN控制器和连接到LAN的外围设备之间的信号路径。 其余的频道提供数字有线电视信号。 LAN通道和数字有线电视频道都组合在同一根同轴电缆上。 电缆剥离器可以是多路复用器/解复用器或陷波滤波器。 或者,通道剥离器可以将频率以外的频率信道分配给LAN,并且保持接收到的有线电视信号。 LAN控制器可以通过使用时分多址协议来为耦合到LAN的每个外围设备分配时隙来创建附加的通信信道。

    • Apparatus for linking multiple baseband telephone lines to provide broadband communication. The apparatus comprises a broadband port, a plurality of baseband ports, and a controller. The broadband port provides connection to a broadband device or broadband communication line. The baseband ports provide connection to baseband communication lines. The controller integrates baseband data streams accepted at the baseband ports into a broadband data stream for transmission at the broadband port, and/or demultiplexes a broadband data stream received at the broadband port into baseband streams for transmission at the baseband ports. The baseband data include message data corresponding to the message data of the broadband stream, and control data describing an interrelationship among the message data, for controlling integrating of said baseband message data. The telephone numbers of baseband communication lines for use by the controller are automatically determined. The invention allows an individual to use multiple plain old telephone service (POTS) lines in combination to emulate the capability of a broadband line.
