DSLAM – DSL Access Multiplexer

A DSLAM (DSL Access Multiplexer) is used as an aggregation point for subscriber traffic within DSL systems. It separates the voice frequency signals from the high-speed data traffic and controls, thus routing DSL traffic between the subscriber’s end-user equipment, e.g. router or modem, and the service provider’s network. IP DSLAMs are now being deployed, which provide much of the functionality traditionally found in a B-RAS.
