What is DSLAM?

A DSLAM (Digital Subscriber Line Access Multiplexer) is a network device, usually located in a telephone exchange, that connects multiple customer Digital Subscriber Lines (DSLs) to a high-speed digital communications backbone. The DSLAM aggregates the DSL connections, converting them into a format suitable for transport over the backbone network, typically using Asynchronous Transfer Mode (ATM) or Ethernet. It's a key component in delivering broadband internet services to homes and businesses over existing telephone lines.
