摘要： Whenever a DSLAM or a network node receives a Group Join message, it compares the MAC address of the originating STB to that of previous Join messages with their existing connections. If a match is found, then the DSLAM will initiate a GSQ for the group of the matching previous Join request. If there is not enough resources to satisfy the requirements of Group Join messages, then it may either be ignored, or queued for later processing, once the normal GSQ sequence is complete and resources are available. If the multicast group is no longer needed, the connection to the group is then terminated, as per normal GSQ processing. This frees up bandwidth for any new Join messages. The normal GSQ processing clears the trouble caused by the loss of Leave Message.

摘要翻译： 每当DSLAM或网络节点接收到组加入消息时，它将原始STB的MAC地址与先前连接消息的MAC地址与其现有连接进行比较。 如果发现匹配，则DSLAM将为匹配的先前连接请求的组发起GSQ。 如果没有足够的资源来满足组加入消息的要求，则一旦GSQ序列完成并且资源可用，则可以将其忽略或排队等待进行后续处理。 如果不再需要组播组，则根据正常的GSQ处理，终止与组的连接。 这释放了任何新的加入消息的带宽。 正常的GSQ处理可以清除由于丢失留言而导致的故障。

摘要： A method and apparatus for communicating functional characteristics of nodes in a communications network to the network manager in the network is presented. This is accomplished by defining a bit field that indicates whether or not a particular functions or services are supported by a particular node. The bit field for each node within the communications network is communicated to the network manager which stores the bit fields for each node within a database. The database is then utilized to perform network management functions, as it informs the network manager whether a particular service/feature is available on the node to which the bit field corresponds.

摘要： A multi-shelf communication system for a communication switch having shelves is provided. There is a master generating commands and receiving status signals, slaves associated with the master, a communication controller per slave, a downstream communication link providing a multiplexed signal of communications from each controller and providing a demultiplexed signal split from the multiplexed signal to each slave, an upstream communication link from each slave to its controller, and a timing arrangement controlling transmission times for the downstream communication link. Each slave can be located on one the shelves and receives commands, executes local commands responsive to the commands and generates status signals for the master. Each controller receives commands, transmits commands to its slave and receives status signals and provides information relating to the status signals to the master controller. Local commands replace other commands directed by the master to the slave. Each slave communicates independently with the master.
