A DSLAM aggregation topology VLAN bundling mechanism includes an edge device port that receives a packet from a Digital Subscriber Line Access Multiplexer (DSLAM) device, the packet including an inner Virtual Local Area Network (VLAN) tag that identifies a Digital Subscriber Line (DSL) subscriber. A processor of the edge device adds an outer VLAN tag to the packet, the outer VLAN tag identifying the DSLAM and a destination server coupled to an Ethernet access network. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

A test system detects proper connection wiring in a connection frame between a customer's lines and a DSL Access Multiplexer (DSLAM). A multi-loop tester at a central office generates a test signal on low frequency lines to a customer's connection in a connection frame. A signature circuit is electrically connected between the customer's connection in the connection frame for the low frequency lines and the DSLAM. The signature circuit responds to the test signal and generates a signature signal. The multi-loop tester senses the signature signal to verify that the DSLAM is properly connected to the customer's lines.

A remote test unit and method of operation are provided for utilizes the ability of an access matrix ability to route signals. The Remote Test Unit can emulate a central Digital Subscriber Line Modem (DSLM-C) for testing customer premises equipment containing a remote Digital Subscriber Line Modem (remote Digital Subscriber Line Modem). The Remote Test Unit can also emulate a remote Digital Subscriber Line Modem for testing central offices equipment including a digital subscriber line access multiplexer (DSLAM) containing a central Digital Subscriber Line Modem. The Remote Test Unit can also emulate a concentrator connected to the DSLAM, a router connected to the concentrator, an Internet service provider (ISP) connected to the router, and a web site connected to the Internet service provider over the Internet.

An assembled telecommunication exchange cabinet, comprising a hollow body and a base, wherein the body comprises a set of front doors, left and right side doors, a top cover and a heat sink device. A plurality of inlets are disposed on the bottom surface of the body, and a telecommunication exchange device and terminal boards are accommodated inside the body. The body accommodates a Digital Subscriber Line Access Multiplexer and a telecommunication exchange device, which in turn, are connected to the corresponding terminal boards. The left and right side doors and the top cover can be subsequently opened separately after the set of front doors is opened. In addition, the heat sink device of the body is disposed under the top cover. The base of the cabinet is removeably attached to the body; and at least one battery holder is further disposed inside the base to accommodate at least one spare battery.

The invention discloses a TianYi broadband terminal and a webmaster optimization platform thereof. The webmaster optimization platform of the TianYi broadband terminal comprises a terminal optimization module and a webmaster optimization module, wherein the terminal optimization module comprises a DSL (Digital Subscriber Line) Modem optimization module and a home gateway optimization module; and the webmaster optimization module comprises a DSLAM (Digital Subscriber Line Access Multiplexer) webmaster optimization module, an EPON (Ethernet Passive Optical Network) webmaster optimization module and an ITMS (Intelligent Traffic Management Systems) optimization module. The TianYi broadband terminal and the webmaster optimization platform thereof have the advantages that a terminal webmaster automatically sends configuration data by adopting an automatic opening module, the terminal provides performance indexes and parameters according to tasks sent by the terminal webmaster to carry out real-time monitoring, when the terminal and a stub network are faulty, diagnosis and fault recovery are completed through the terminal and the terminal webmaster by adopting a fault treatment module, and the like.

The invention discloses a user safe protection method of wideband access device, for resolving the problem of prior DHCP access method, in which before user requests legal IP address, superior device can not process ACL safe filter based on IP on the report from the port. The inventive method comprises that A, detecting dynamic host setting protocol report on a digit user line access complex device, B, detecting the resource of IP report, to limit and filter the pass of the user report. The invention realizes the filter on user data report at lower layer with simple process, and dynamically bonds user IP and MAC, to overcome the defects of traditional ACL safe mechanism based on IP, to effectively protect device from IP theft internet or attach. When two layers of access devices use the invention, the superior device reduces processed reports, thereby reducing system development complexity and improving system reliability.

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.

A system that incorporates teachings of the present disclosure may include, for example, a set-top box (STB) having a controller to generate a trouble report indicating a malfunction with one or more services, and submitting the trouble report to a mitigation system. The mitigation system can be adapted to detect one or more operational faults in at least one of a Digital Subscriber Line Access Multiplexer (DSLAM), a residential gateway (RG), and the STB, cycle operations of at least one of the DSLAM, the RG, and the STB responsive to detecting an undesirable state of operation of at least one of the DSLAM, the RG, and the STB, and generate a trouble ticket directed to a service agent responsive to detecting that at least one of the DSLAM, the RG and the STB continues to exhibit at least one operational fault. Other embodiments are disclosed.
