A network element comprises a power interface to receive power from a power communication medium; a service interface to provide a telecommunication service over a service communication medium; management interface to receive management data over one of the service communication medium and the power communication medium via at least one primitive; and a control module to monitor the at least one primitive and to control operation of the network element based on the at least one monitored primitive.

Function for controlling line powered network element

In one embodiment, a first device for communicating over a digital-subscriber-line (DSL) line comprises a digital-subscriber-line transceiver to transmit and receive data over the DSL link. A set of one or more performance parameters are associated with the DSL link by which the quality of the DSL link can be determined. The first device further comprises a controller coupled to the digital-subscriber-line transceiver. The controller causes a non-intrusive transmitter adjustment operation to be performed by the digital-subscriber-line transceiver.

Non-intrusive digital subscriber line transmit adjustment method

A method of managing power at an element management system for a power sourcing network element and a power sinking network element of an access network is provided. The method includes identifying a set of primitives for managing power usage at the power sinking network element associated with providing a provisioned service, provisioning at least one instance of a line power manager for the service with the set of primitives, provisioning at least one instance of an associated line power controller at each of the power sourcing network element and the power sinking network element, associating at least one conductive medium with the line power controller, the at least one conductive medium coupled between the power sourcing network element and the power sinking network element, and passing selected ones of the set of primitives to the power sourcing network element and the power sinking network element for use by at least one line power control function of the power sourcing and the power sinking network elements.

Element management system for managing line-powered network elements

A method of controlling power in a network element includes powering the network element by receiving power from a power communication medium and providing a telecommunication service over a service communication medium. The method further includes monitoring a primitive related to the powering of the network element and controlling the powering of the network element based on the primitive.

A system for managing power from a power source for at least one line powered network element in an access network is provided. The system includes a power manager that establishes at least one power criterion for the at least one network element. Further, the system includes a power controller that is responsive to the power manager. The power controller and the power manager communicate to manage operation of the at least one network element based on the at least one power criterion.

Managing power in a line powered network element

A method for processing cells at a user-network interface with automatic identification of virtual circuit identifiers and a testing function is provided. The method includes distinguishing the source of the cell. When the cell is from a first source, the method tests the cell against at least one selected criteria. When at least one test determines the cell is invalid, the cell is marked. When the tests determine that the cell is valid, the method translates a virtual circuit identifier to a default setting and forwards the cell to a queue for further processing.

A system for extending the effective distance of digital subscriber line service is provided. The system includes a central office terminal having a data interface and a plurality of line units. The system further includes at least one communication link, coupled to one of the plurality of line units, that carries signals using digital subscriber line service and at least one remote access multiplexer, coupled to the at least one communication link. The at least one remote access multiplexer includes a plurality of ports that are adapted to provide digital subscriber line service. The remote access multiplexer is adapted to multiplex signals between the plurality of ports and the at least one communication link. Further, the at least one remote access multiplexer is located at a distance from the central office terminal so as to provide digital subscriber line service to user terminals that are located more than 12 kilofeet from the central office terminal.

A method of automatic permanent virtual circuit connection activation is provided. The method includes detects initiation of communication between a first and a second network element at a first reference point. The method further receives at least one virtual circuit identifier of the first network element and learning at least one virtual circuit identifier of the second network element. In addition, the method creates a translation connection between the first and second network elements.

A integrated access device in a communication network. The integrated access device in one embodiment includes a network port, a plurality of telephony ports, a data port and communication circuit. The network port is adapted to provide dynamic time division multiplex (TDM) interface to a communication network. The plurality of telephony ports are adapted to provide telephony service to subscriber premises equipment. The data port is adapted to provide digital subscriber line (DSL) service to subscriber premises equipment. The communication circuit is coupled to the network port, the plurality of telephony ports and the data port. Moreover, the communication circuit is adapted to carry voice and data signals between the network port and the plurality of telephony ports and the data port. In addition, the integrated access device is line powered over the network port.

Methods for bit-level control of dynamic bandwidth allocation are adapted for use in multi-node channelized transport systems. A single status bit is used to indicate the desired allocation status of each transport channel for which dynamic allocation is permitted or desired. The status bit has a first logic level indicative of a desire to have a first allocation status, such as allocated for data traffic, and a second logic level indicative of a desire to have a second allocation status, such as allocated for voice traffic. The status bit may be repeated multiple times within a frame to mitigate the effects of transmission errors. The values of the status bit or bits can be maintained across node boundaries without regard to the framing mechanisms or multiplexing techniques used by the transport system, thus permitting dynamic bandwidth allocation beyond the local loop.
