DSLAM (Digital Subscriber Line Access Multiplexer)
A DSLAM (Digital Subscriber Line Access Multiplexer) is a network device, usually at a telephone
company central office, that receives signals from multiple customer Digital Subscriber Line (DSL)
connections and puts the signals on a high-speed backbone
line using multiplexing
techniques. Depending on the product, DSLAM multiplexers connect DSL lines with some combination of
asynchronous transfer mode (ATM), frame
relay, or Internet
Protocol networks. DSLAM enables a phone company to offer business or homes users the fastest
phone line technology (DSL) with the fastest backbone network technology (ATM).
