    • Public or private remote access infrastructures in a communication system are used to facilitate communications between a remote site and a centrally located diagnostic center using only local telephone calls. The diagnostic center as well as one or more remote sites at which monitored equipment is located are coupled to a wide area network (WAN). When data are to be transferred from a remote site to the central diagnostic center, the remote site initiates a local telephone call to a point-of-presence (POP) server on the WAN backbone. This could be an Internet Service Provider (ISP) if the Internet is used, or an intranet if a private network is used. Data are then transferred to the POP server. To complete the transfer, the diagnostic center retrieves the data from the POP server using the public or private wide-area network (the Internet or intranet). The data transfer can be performed either on a scheduled basis, or when an alarm condition is detected at the remote site. The central diagnostic center can use a wireless paging service to prompt the remote site to couple to the POP server.
    • 通信系统中的公共或专用远程访问基础设施用于仅使用本地电话呼叫来远程站点和位于中心的诊断中心之间的通信。 诊断中心以及被监测设备所在的一个或多个远程站点耦合到广域网(WAN)。 当数据从远程站点传输到中央诊断中心时,远程站点发起本地电话呼叫到WAN骨干网上的一个现场(POP)服务器。 如果使用互联网,这可能是互联网服务提供商(ISP),如果使用专用网络,则可能是内部网。 然后将数据传输到POP服务器。 要完成传输,诊断中心使用公共或专用广域网(Internet或Intranet)从POP服务器检索数据。 数据传输可以按计划执行,也可以在远程站点检测到报警条件时执行。 中央诊断中心可以使用无线寻呼服务来提示远程站点耦合到POP服务器。
