The Types of Phone Wiring Used In Residential & Commercial Installations

A phone wire contains at least one twisted pair of copper wires. Residential and commercial phone wires typically contain four strands supporting two phone lines. A phone cable may also carry six or more strands to support additional lines.

A standard two-pair wire includes four colored wires: red, green, yellow, and black. Red and green make one pair of wires, while yellow and black make another. Newer lines have different color conventions, known as Color Code Two, and under the new color code, a blue, orange, green, or brown wire pairs with a white wire.

Phone cables typically belong to the following categories: RJ11/6P4C, RJ12/6P6C, and RJ45/8P8C. RJ means “Registered Jack.”

  • RJ11/6P4C cables have six contact positions and four gold-plated conductors on their plugs
  • RJ12/6P6C cables have six contact positions and six conductors
  • RJ45/8P8C cables have an eight-position, eight-conductor modular plug

Phone Wiring Methods

Most electricians wire phone systems using either the daisy chain or the home-run wiring methods.

  • In daisy-chain wiring, several phone outlets connect to a single circuit. The wiring starts at a junction that connects to the service provider’s jack and proceeds between jacks. Daisy-chain wiring is a quick and straightforward installation system.
  • In home-run wiring, each jack connects to a wire junction separately. Although this installation technique requires more labor and hardware, it makes upgrades easier and limits any wiring damage to one jack.

What Can Cause Damage To Phone Wiring?

While most think phone problems result from network issues, difficulties such as line static, poor call quality, dropped calls, or difficulty making or receiving calls can be due to issues with your phone’s wiring. Because wires are located inside the walls, many people think they’re safe from damage. However, there are various ways that phone wiring can be degraded or damaged.

Power Surges or Lightning Strikes

Lightning strikes can cause power surges that cause damage to phone wiring. While not every lightning strike will cause damage to your electrical system, if your building receives a direct strike it could cause damage to wiring, outlets, electrical panels, and other electrical system components.

Rodent-Chewed Wiring

Rodents like mice, rats, and squirrels can damage phone wiring, especially in older buildings with unprotected wires. Unlike other causes of wire damage, it’s usually fairly easy to tell if your wires have been chewed through by a rodent. Apart from replacing damaged phone system parts, you’ll need to protect your new wiring from rodents. Rodent-proofing your building and encasing your outdoor lines in hard covers can help minimize rodent attacks on your wiring.


Short-circuiting can happen when two bare phone wires touch because of a position shift or an improper installation. A short circuit may make you unable to make or receive phone calls on your landline. Luckily, short-circuiting in phone wires doesn’t lead to dangerous voltage surges, but it’s important to call a technician to resolve the problem.

Apart from separating the wires or replacing a damaged phone wiring section, our technicians will investigate the problem that caused the short-circuiting and suggest or implement solutions.

Reversed Wires

Reversed wiring can occur when the phone line installer connects two lines on the phone jack incorrectly. Incorrect wiring can cause your entire phone system to malfunction or fail. If wiring was done incorrectly, one of our licensed commercial electricians should be able to identify it pretty quickly.

Old Phone Wiring

Old phone wiring often suffers from wear and tear, which may not be noticeable until the system stops working. Old phone points may also become problematic if they are unsuitable for ADSL internet service. Upgrading new phone wiring will improve connectivity and resolve wear-related problems.

Open Circuit

An open circuit happens when a phone wire breaks or loosens and doesn’t connect to the phone point. If this occurs, the recipient will hear the phone ring but will not hear the caller on the other end.

Our phone wiring technicians can locate the disconnected wire and reposition or replace it to resolve the open circuit issue.

Common Questions About Phone Jack Wiring

Here are some common questions we receive from our clients about phone jack wiring installation.

Can I install a phone jack myself?

While some people opt for DIY phone jack installation, it can lead to many problems. Phone wiring is delicate, and improper installation can cause short-circuiting, open circuits, and other issues. DIY installation can compromise call quality, cause your landline to fail, or even lead to fires if the wiring was not done to code.

A certified electrician can install a phone jack easily, quickly, and efficiently. With an electrician, you’ll receive a labor warranty that ensures reliable support if your landline stops working.

How much does it cost to install a telephone jack?

The cost of phone jack installation will vary based on the size and complexity of the job. It could range from under $100 to several thousand dollars, depending on material costs, the amount of labor involved, how many jacks you need, and whether your project requires any additional components like phone wiring. Call us today to find out how much you might expect to pay for phone jack installation.

How much does it cost to install a landline?

Landline installation costs in Florida vary depending on various factors. The project’s size and complexity, your property’s topography, estimated work hours, material costs, and the number of outlets are all examples of what determines the price of an installation.

For example, if your property doesn’t allow convenient inter-wall access, the technician may need to drill holes in the wall and floor to install the phone wiring. This time-consuming extra work increases project costs. If there’s a rodent infestation and your cables need to be secured against chewing, this may entail additional labor and materials.

For a precise landline cost estimate, call Suncoast Power. Our team will provide a detailed offer based on your telecommunication needs, timeline, and budget.

What is the color code for a phone line?

Under the old color code, a phone cable’s red and green wires make one phone line, while the yellow and black wires make another pair.

If your phone wiring supports more than two lines, the extra lines will have different colors. For example, line three will be blue and white, while line four will be orange and brown.

Also, new lines have an updated color code (Color Code Two). In phone systems that use the new code. Line one will be white and blue, while Line 2 will be white and orange.
