摘要： A system and method for redundant synchronizing to a reference clock for data communications. A determination is made whether a first data stream and a second data stream are available. The first data stream and the second data stream are received through opposing directions of a communications ring. A first data packet and second data packet are received at a remote node in response to the first data stream and second data stream being available. A timing characteristic of the first data packet and the second data packet correspond to a tick of a reference clock. The tick of the reference clock is extracted utilizing a timing characteristic of the first data packet or second data packet in response to the first data stream or the second data stream being available. A secondary clock is disciplined with the reference clock by adjusting the secondary clock based on a difference between times measured by the reference clock and the secondary clock to generate a clock signal. The clock signal is communicated to one or more interfaces for distribution.

摘要： A system and method for synchronizing a plurality of networked fire alarm panels is disclosed. A plurality of fire panels (i.e., nodes) are arranged on a peer-to-peer network, such as a token ring network. One node is designated as a SyncHost, and the remaining nodes are periodically reset to the clock time associated with the SyncHost to ensure all nodes remain substantially synchronized to a single time. Upon alarm, the visual notification devices (i.e., strobe lights) of all the fire panels (nodes) will flash at substantially the same time. To accomplish the synchronization, the SyncHost sends periodic attendance polls around the network, noting the transit times of the polls. The nodes also note times associated with the polls. The SyncHost sends a sync message to the nodes, and each of the nodes resets its clock according to the sync message and internal compensations. Other embodiments are disclosed and claimed.

摘要： A novel clock method and synchronization mechanism for recovering and distributing a centralized clock source synchronously over legacy asynchronous network devices such as legacy optical Ethernet devices that do not support synchronous Ethernet. An external device functions transparently to provide legacy optical Ethernet devices a clock synchronization and distribution mechanism. The external devices implement a clock conversion scheme whereby multiple clocks having diverse rates are converted to clock signals all having a common rate. One of the converted clocks is selected and all downstream clock signals are then derived from this clock. A high quality clock source located anywhere on the network is distributed throughout the network thus turning an asynchronous Ethernet network into a synchronous Ethernet network. Synchronous TDM data streams can then be easily transported over the Ethernet network.

摘要： A system matches frame counter values between a timing master and one or more slave devices in a synchronous network. To detect synchronization losses, a timing master counts transmitted frames of a continuous data stream. When a synchronization loss occurs, the timing master transmits a message to the slave devices that includes a synchronization frame counter value. The message synchronizes the frame counter value of the timing master to the frame counter value of the slave devices.

摘要： Packets used for distributing timing information over a Resilient Packet Ring (RPR) are generated by encoding Synchronization Status Messaging (SSM) messages into IEEE 802.3ah OAM packets (or any other OAM packets, such as those defined in ITU Y.1731). Information indicating the direction that each message is to be transmitted around the RPR ring is also encoded in the packets in either the spare bits of the SSM messages or in the Type-Length-Value (TLV) bytes of the IEEE 802.3ah OAM packets or Y.1731 OAM packets. RPR protection is disabled for the packets carrying the SSM messages and the packets are transmitted to adjacent network nodes in the directions specified by the information encoded in the messages. Information encoded in received packets specifying timing quality and direction of the received messages is observed and compared to determine which timing information included in the messages to use for clock timing.
摘要翻译：用于通过弹性分组环（RPR）分发定时信息的分组是通过将同步状态消息（SSM）消息编码为IEEE 802.3ah OAM分组（或任何其他OAM分组，例如ITU Y.1731中定义的那些）来生成的。指示每个消息围绕RPR环传送的方向的信息也被编码在SSM消息的备用位或IEEE 802.3ah OAM数据包的类型长度值（TLV）字节中的数据包中，或 Y.1731 OAM包。对于携带SSM消息的报文，RPR保护被禁止，并且分组按照消息中编码的信息指定的方向发送到相邻的网络节点。观察并比较指定定时质量和接收到的消息方向的接收分组中编码的信息，以确定包括在用于时钟定时的消息中的定时信息。
