What Is DSL Port? (Explained)

We have plenty of knowledge about the DSL technology that how the data transmission in DSL takes place via the telephone signals. At this point, many people have confusion about what exactly is DSL port and how does it set up and other relevant details about the DSL port. So, here we go. DSL port is used to connect a telephone landline with internet broadband services. Most of the people confuse DSL port with the WAN port.

However, there is a huge difference that differentiates them. WAN port is separately created for the connection between the separate modem and Ethernet cord whereas the DSL port is a spot where phone lines get in contact with the modem.

WAN Port And DSL Port Are Not Same:

We have given a quick idea in the above section that these two aren’t the same in any way. They undoubtedly tend to serve for home routers. However, the functions of both of these ports are different for different types of routers. How? The background states that there are two types of the home router; a built-in modem router and the one without the modem.

The modem is responsible for providing the connection to one specific type of broadband, either an Ethernet cord or the telephone landline. Therefore, routers with the built-in modem are connected to the telephone landline with the help of a DSL port on the router. On the contrary, the routers without a built-in modem are required to have a separate modem which would provide a connection to the broadband service. Such routers do have WAN ports. In such a way, DSL port and WAN port are quite different from each other however they perform a similar function.

Moreover, when a particular port has been labeled specifically with the “DSL port” then the connection that port provides is reserved for a Point-to-Point Protocol over ATM also called PPPoA WAN Connection. This connection port is usually an RJ11 port that gets connected to your landline with the help of a micro-filter using a total of two wires.

On the other hand, A WAN port is just an RJ45 Ethernet connection port that gets connected to the network port of a PPPoA-based modem and used as an Ethernet with the eight wires combined in total. At this point, you must have clear concepts about the WAN port and DSL port and how they are not the same.

How Does DSL Work?

After having a fair idea of what DSL port is, one needs to know about the step by step working of DSL. the function of DSL revolves around the transmission of data within the telephone landline. Here’s how the internet data flows:

  • Upon requesting or putting any command to your computer or simply browsing on any web page, the data is generated by your device.
  • Then the generated data keeps on flowing from the DSL port to your DSL modem.
  • Upon passing through the DSL modem, the data then flows back to the telephone landline and the wall jack.
  • The transmitted data then tends to travel to the outside router of your phone box with the help of your landline cabling and wiring within the premises of your house’s wall.
  • The data after that travels straight to the DSL’s Central Office building nearest in your neighborhood. However, if you don’t have one near then the DSL internet speeds thus the data transmission might be problematic for you. Although, if have one near to your house then the transmitted data travels downright to your ISP’s network
  • Upon reaching your internet service provider, the data then finally goes out straight to the Internet providing you the desired webpages that you accessed.

So, this is how the data transmission works in the DSL technology.

Steps To Connect DSL Modem To Your Computer:

After having your DSL Internet established by the DSL port, here is how you connect your DSL modem to your computer:

Before you start installing the equipment, make sure you have got DSL modem, power adopter, network cable, and the telephone cord.

  • Plug one end of your network cable into your DSL modem’s back.
  • Plug the other end into the network adaptor.
  • Plug your telephone cord to the DSL modem and your telephone’s wall jack.
  • The process would be completed upon the flashing of lights.
