How to Install a PBX Phone System

A small business private branch exchange system gives each of your employees access to multiple phone lines through their desk’s phone. The systems are easy to operate and provide great support, but their installation can be tedious and time-consuming. Many hardware providers offer phone support that may aid the final programming of your PBX platform.

  1. Locate an area central to your phone lines and employees; this is where you will mount your key service unit, the brain behind your PBX system; it must be connected to your phone lines and your phone units.
  1. 2.Attach the KSU to the wall with its mounting kit and your electric screwdriver. You may need to start the mounting holes with an electric drill.
  2. 3.Plug your circuit cards into the KSU. These are often used for voicemail and will have dedicated, labeled slots for each card. They are often found on the side of the KSU, although some units will require you to remove its casing for access to the slots.
  3. 4.Connect your telephone lines directly to the KSU using telephone cords. These are the dial tone lines provided by your phone company.
  4. 5.Run a telephone line from the KSU to each of your employee’s phone units.
  5. 6.Plug in the KSU to a wall outlet for power and watch to make sure its system lights all illuminate.
  6. 7.Turn on all of your employee’s phone lines and watch for the proper light to signal that it has connected with the KSU.
  7. 8.Use the setup and programming guide provided by your PBX vendor to properly code your unit. These directions vary greatly across models, so follow them explicitly.
  8. 9.Test your phones by placing and receiving calls once the programming is complete.
