Siemens DSLAM SURPASS hiX 5625A Digital Subscriber Line Access Multiplexer (DSLAM) allows telephone lines to make faster connections to the Internet. It is a network device, usually located at a telephone company central office (CO), that connects multiple customer Digital Subscriber Line (DSL)s to a high-speed Internet backbone line using multiplexing techniques. The DSLAM creates a network similar to a LAN but not subject to Ethernet distance limits, thus providing an Internet connection for the subscribers.
