Understanding the Basics of Telephone Wiring

What our customers say

Your phone lines at home are important. It is your line connection for communication and it can also be a source of aid to you in emergency cases.

As such, it is highly useful to know the foundation and basics of these telephone wires that run through your home. If a line disconnection or any issue occurs, you won’t panic as much. Should the need arise, this information can come in handy to make sure that you’ll know what to do in an emergency. 

Wiring jobs are less complicated than expected. There are many things you can do first before imploring the help of your local electricians. You can call them initial steps or knowledge must-haves just to make sure that when the situation arises, you can deal with it firsthand while waiting out for your electricians to arrive. This is definitely useful rather than just sitting around.

Telephone Service Provider

It is important you know the service provider of your telephone lines. Your service provider provides a Network Interface via a junction box. Your telephone company usually puts it near the electrical meter so it’s as accessible as possible. This box is the centre point of your wiring lines that lead to your home. There’s a point in that box that you can’t have access to. The service provider locks a portion that is only accessible to them. 

Telephone Wires

Telephone wires come in pairs. One end is called the “tip wire” while the other is called “ring wire.” Connect the tip wire from the Network Interface box into the tip wire of the telephone jack in your wall.

The same goes for the ring wire. You’ll need to connect it to the ring wire of the telephone jack from the wall socket. Layout the wiring across the area and find the outlets inside your home. Connect them appropriately.  

Most telephone wires follow a colour code. Tip wires usually come in green, black and blue. Moreover, they are respectively paired with red, yellow or white ring wires. Usually, there are two pairs of wire coming from the box towards your home. However, there are two extra spare pairs just in case you want additional phone lines in your home.

Basic tools

It’s quite useful to have some tools in hand for when you need to work things out on your own. For urgent cases, your electrician might arrive a bit later than expected. If you know well enough the know-hows of your telephone wiring, you can attend to it first. These are some of the basic tools you’ll need if you need to give initial work to your phone lines:

  • Screwdriver or screwdriver sets with retractable various sizes
  • Longnose Pliers
  • Cutter or a pocket knife
  • Tape measure

Common issues

Your phone lines will definitely have some issues that will force you to seek repairs or replacements. Just like electrical wiring, these wires in your telephone wires also experience problems from external sources or constant wear and tear from periods of constant usage. Some of the most common issues you’ll face are the following:

  • Moisture gradually seeps through your phone lines, causing faulty lines. Long lengths of wire also cause some connection inconsistencies. 
  • The age of sockets also affects your phone line connections. The older your sockets are, the slower the transmission will be due to corrosion and gradual wearing out of the sockets.
  • Vermin might be living within the premises of your electrical systems. Rats and mice might be chipping away your lines causing more issues in your connection.
