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.

Types of Broadband 1.DSL

2. Cable 3. Fiber optics

4. Satellite

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.

BROADBAND CONNECTIONThis document describes the three most common

techniques used to share a broadband connection with multiple computers.

Method 1:Sharing a broadband connection using a Microsoft Internet Connection Sharing

Method 2:Sharing a broadband connection using a hardware broadband router

Method 3:Sharing a broadband connection using a Linux router

Method 1:Sharing a broadband conncetion using a hardware broadband router

Method 2:Sharing a broadband conncetion using a hardware broadband router

Method 3:Sharing a broadband conncetion using a Linux router
