Digital Subscriber Line Access Multiplexer - Hardware Details

Hardware Details

Customers connect to the DSLAM through ADSL modems or DSL routers, which are connected to the PSTN network via typical unshielded twisted pair telephone lines. Each DSLAM has multiple aggregation cards, and each such card can have multiple ports to which the customers lines are connected. Typically a single DSLAM aggregation card has 24 ports, but this number can vary with each manufacturer.

The most common DSLAMs are housed in a telco-grade chassis, which are supplied with (nominal) 48 volts DC. Hence a typical DSLAM setup may contain power converters, DSLAM chassis, aggregation cards, cabling, and upstream links. The most common upstream links in these DSLAMs use Gigabit Ethernet or multi-gigabit fiber optic links.

Famous quotes containing the words details and/or hardware:

    Then he told the news media
    the strange details of his death
    and they hammered him up in the marketplace
    and sold him and sold him and sold him.
    My death the same.
    Anne Sexton (1928–1974)

    A friend of mine spoke of books that are dedicated like this: “To my wife, by whose helpful criticism ...” and so on. He said the dedication should really read: “To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harper’s instead of The Hardware Age.”
    Brenda Ueland (1891–1985)
