Internet Types: Dial Up, ISDN & DSL

Dial Up, ISDN, & DSL

In this lesson we’re going to contract and compare different types of internet connections.

The internet is a huge web of differing networks that all interconnected and connecting to it is also accomplished by varied methods.

The entity that facilitates that connection is the ISP, internet service provider, they offer pathways that link individual computers as well as networked environments thru their proprietary data center and from that data center send signals that connect you to the internet.

ISP provides connectivity thru the following mediums:

  • Dialup (POTS for plain old telephone system, or publically switched telephone network)
  • ISDN
  • Cable
  • Cellular
  • Line of Site, and
  • Fiber

We examine each of these connection types, discuss their pros and cons, technical capabilities and limitations as well as diagram how they work.

We begin with Dialup, which uses digital signals that transmit over  telephone line using a modem (modulator).  It goes over telephone lines as an analog signal.  We’ll diagram this process and you’ll see how this process works.

ISDN uses telephone lines BUT in a totally different way, “multiple data channels.”  ISDN stands for Integrated Services Digital Network, it uses a terminal adapted.  You’ll learn what a BRI & PRI mean, what their transmissions rates are and how they different from the standard dialup connection is.

Then we examine DSL, which stands for Digital Subscriber Line.  DSL connectivity also uses telephone lines, but it uses a significantly higher signal and uses a splitter for voice and data transmission over a single line.

You’ll learn how the same line uses DSL vs. ISDN/Dialup differently and what its standard transmission speed is, and what Asymmetric DSL and how it differs from regular DSL both in terms of infrastructure and transmission capabilities.
