    摘要: A communications system, such as a Digital Subscriber Line Access Multiplexer (DSLAM), or corresponding method increases available bandwidth for transmission of data, video, and audio to a customer premise, or curb node for further distribution to customer premises, within a network. In one embodiment, a system comprises a host digital terminal (HDT) including an Ethernet switch unit and multiple optical interface units coupled via a bus. The optical interface units are configured to communicate over an optical communications link with broadband cards of optical network units (ONUs). The ONUs also include data cards coupled to the broadband cards via a bus. The data cards are configured to communicate over end user communications links to end user nodes.

    摘要: A method and system detects a network connection in a communications system, such as a narrowband communications system, using Virtual Local Area Network (VLAN) identification. In one embodiment, a first node transmits a message to a specific second node among a group of second nodes. The message from the first node includes a source Medium Access Control (MAC) address, a broadcast address, and a unique VLAN identification corresponding to a port on the first node. The specific second node processes the message, and then transmits its own MAC address to the first node, along with the unique VLAN identification received in the original message from the first node. The first node then updates stored information about the second node and uses the information in future communications to the second node.
