Types of Telephone Systems

Understanding your businesses requirements will help you choose the correct telephone system for your business.

There are three main types of business telephone systems:

  1. KSU-Less Systems
  2. Key Systems
  3. Private Branch Exchange System

KSU-Less System

KSU-less systems are recommended for smaller businesses who require less than 10 extensions or have less than 10 employees working for them. However it should be noted that the limited features of KSU-Less systems does mean they are not necessarily suitable for all small businesses.

These systems are usually the least costly of all the systems available by a considerable margin. Because these systems are the cheapest telecom's, companies do not usually install or maintain them.

This means you will have to purchase the telephones and necessary hardware and install them yourself, which may present system reliability problems for the business. One other problem with KSU-Less systems is that they are often prone to crosstalk issues.


Key (KSU) Systems

Another option is Key Systems, which are suited to businesses that require less than forty extensions. These work by using a Key System Unit (KSU) as a central control, giving these phone systems features that do not exist on ordinary domestic telephones.

KSU Systems are typically priced between KSU-Less Systems and PBX systems. It is possible to purchase a hybrid system which means than a Key System can offer many of the facilities traditionally only offered by PBX systems. Both Keys Systems and Hybrid Systems are available to be installed and maintained by telecom's companies.


Private Branch Exchange (PBX) Systems

PBX Systems are most suited to businesses that require more than forty phone extensions, or businesses that require sophisticated specifications for their phones.

PBX systems are more expensive than KSU-Less Systems but the price has fallen in recent years so there is now less of a difference between the two. On the other hand, telecoms companies are on hand to offer to install and maintain PBX systems, which is not the case for KSU-less systems.
