摘要： DSLAMs and associated methods of installing DSLAMs are disclosed where the components of a DSLAM are distributed in a DSL network. A distributed DSLAM as provided herein includes digital signal processing components implemented in a centralized system (e.g., a central office) on the DSL network. The distributed DSLAM also includes digital/analog conversion components (e.g., analog front end (AFE) components) implemented in a distributed node on the DSL network that is remote from the centralized system. The distributed DSLAM also includes a spanned communication link (e.g., optical fiber) between the digital signal processing components and the digital/analog conversion components. The digital signal processing components in the centralized system are considered more likely to be upgraded than the digital/analog conversion components in the distributed node. Thus, upgrades for the DSLAM can frequently be performed at the centralized system instead of at the distributed node.

摘要： A method and apparatus for selectively terminating sealing current in an asymmetric digital subscriber line modem is provided. The technique comprises providing a mechanism (e.g., a resistor or suitable current sink) to a DSL modem (e.g. an ADSL modem or any XDSL modem used where POTS is underlying service). The mechanism is operable to be dynamically switched on and off and to operate under low current conditions. The system allows for provision of DSL (e.g., ADSL or XDSL where POTS is the underlying current) in the absence of plain old telephone service (POTS) and for improved performance.
