    摘要: Apparatus and methods for providing remote control and control redundancy for distributed communication equipment are disclosed. An expansion system in a distributed communication equipment architecture is controlled by a controller in a host system. Control information is exchanged between the host system controller and an expansion system in communication signals that are processed by one or more communication modules such as line termination cards in the expansion system. Communication signals are transferred to the communication module(s) through an expansion system control device, and control information is then transferred back to the control device. Control information may also be transferred from the expansion system control device to the host system through the communication module(s). This simplifies the design and lowers the cost of the control device, which does not process received signals. Control redundancy is provided in some embodiments by implementing multiple communication modules and corresponding communication links.

    摘要: An xDSL access system initiates an ATM point-to-multipoint connection with a source connected to the ATM network responsive to an IGMP control message received from one of the end user systems requesting a particular data stream. The source formats the data stream into IP packets having an IP multicast address. These IP packets are first encapsulated into Ethernet frames and then the source ATM encapsulates the Ethernet frames into ATM cells and launches the cells into the ATM network. The xDSL access system receives these cells over the ATM point-to-multipoint connection and transmits the cells to the end user system. The end user receives the xDSL modulated signal, reassembles the IP packets from the ATM cells and sends the packets to the end user; and then the end user receives the IP packets and re-formats them into a particular data stream.

    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: IGMP is a protocol for managing and controlling multicast of data streams to a plurality of end users connected to a telecommunications network through an access system. A novel implementation of IGMP for multicasting data streams in an XDSL access network system is disclosed. DSLAM (Digital Subscriber Line Asynchronous Multiplexer) or ASAM (ATM Subscriber Access Multiplexer) is used in the access network system and interfaces between the telecommunications network and the plurality of end users. IGMP signals are terminated at LT (Line Termination). A better scalability of the access system can be achieved, resulting in increased numbers of end users.
