What is Broadband?Broadband Internet service truly is the
most used form of Internet access because of its high access speeds; it is offered in four different forms, DSL (or
Digital Subscriber Line), also fiber-optic, cable, and satellite. The old dial-up
connection is the only non-broadband internet service available, and even
though it is cheaper, most Internet users are moving towards the faster broadband
Internet connection.

BROADBAND ACCESSBroadband access technology is broadly classified into two categories. They are Wired Line &
Wireless and further classified as detailed in the following .
Broadband Access Technology
Wired line Wireless DSL(Digital sub’s line) 3G Mobile Cabel Modem Wi-Fi PLC(Power line comm.) WIMAX Optical Fibre Technology FSO(Free space optics)
DSLAM: FUNCTIONSA digital subscriber line access multiplexer DSLAM, is a network device, often located in the telephone exchanges of the telecommunications operators. It connects multiple customer digital subscriber line (DSL) interfaces to a high-speed digital communications channel using multiplexing techniques.
. DSLAM is an integrated hardware & software system that allows the user to access broadband services as well as originate and terminate telephone calls over the same single pair of copper wires.
. DSLAM aggregates the subscriber lines.
Tier 1 and Tier 2 LAN Switches.LAN SWITCH: Lan Switches provide gigabit Ethernet interfaces and fast Ethernet interfaces for connecting internetworking elements such as BRAS,DSLAM etc.
.Tier 1 switches are gigabit Ethernet aggregation switches to which BRAS and Tier 2 LAN switches are connected through GE/FE interfaces.
.All DSLAM are aggregated to Tier 2 switches through FE interfaces except 48 ports DSLAM are aggregated through GE interfaces.
