摘要： A system for providing remote access and control of electronic devices connected to a CEBus network includes a remotely located master node, e.g., a utility server controller, which is linked to the CEBus network via an ATM-based broadband access network ("BAN"). A proxy node is provided on the CEBus network, wherein the proxy node is also linked to the master node via the BAN. The proxy node includes a power monitoring module, which constantly monitors the power supply to the proxy node, e.g., of a residential home at which the proxy node is located. In the case of a power failure, the monitoring module detects the failure and notifies a power outage module. The power outage module generates a power failure alarm message, which is forwarded to the master node in the form of a CEBus link protocol data unit ("LPDU"). In particular, the proxy node packetizes the LPDU alarm message into ATM transmission format for transport to the master node over the BAN. Upon receipt of the LPDU alarm message, the master node notifies the appropriate utility company about the power failure, based on specific identifying information contained in the LPDU alarm message.

摘要： A communication protocol proxy enables a CEBus network to be mapped across a non-CEBus network, thereby allowing a remotely located node (e.g., a controller) to communicate via a non-CEBus network with electronic devices connected to the CEBus network, while still conforming with the EIA/IS-60 protocol requirements. In a preferred embodiment, a proxy node is provided on a CEBus network, wherein the proxy node is also connected to a non-CEBus network, (e.g., a wide area network ("WAN")), such that a remotely located controller on the non-CEBus network may communicate with a device on the CEBus network by transmitting messages to the proxy node over the non-CEBus network. The proxy node then forwards the message to the respective CEBus device over the CEBus network. If the message requires a CEBus Ack message response, the CEBus device transmits a CEBus Ack message to the proxy node, so that it is received within the time interval specified by the CEBus standard. On receiving the CEBus Ack message, the proxy node transmits a non-CEBus standard acknowledge message to the controller, which can be received over an extended time interval. If the message does not require a CEBus Ack message response, the proxy node still transmits a non-CEBus standard acknowledge message to the controller in order to verify receipt of the message.
摘要翻译：通信协议代理使CEBus网络能够跨非CEBus网络映射，从而允许位于远程的节点（例如，控制器）通过非CEBus网络与连接到CEBus网络的电子设备通信，同时仍然符合具有EIA / IS-60协议要求。在优选实施例中，在CEBus网络上提供代理节点，其中代理节点还连接到非CEBus网络（例如，广域网（“WAN”）），使得位于远程位置的控制器非CEBus网络可以通过在非CEBus网络上向代理节点发送消息来与CEBus网络上的设备进行通信。代理节点然后通过CEBus网络将消息转发到相应的CEBus设备。如果消息需要CEBus Ack消息响应，则CEBus设备向代理节点发送CEBus Ack消息，以便在CEBus标准指定的时间间隔内接收。在接收到CEBus Ack消息时，代理节点向控制器发送非CEBus标准确认消息，可以在延长的时间间隔内接收。如果消息不需要CEBus Ack消息响应，则代理节点仍然向控制器发送非CEBus标准确认消息，以便验证消息的接收。
