Replace Your Aging
Phone Equipment

Maintain legacy (old) telephone equipment or replace it with a new phone system? It is the classic question we hear daily. If you’ve made the decision to replace your phone system, here are some considerations: Size of phone system and type of telephone equipment.

Types of Commercial Phone Systems

There are three major types of commercial phone systems on the market today: key systems, Private Branch Exchange (PBX) systems, and KSU-less phones. The type of system you choose will depend on how many stations (extensions) you need and what features you require. In addition evaluating VoIp Telephone technology for your business may be a consideration.


PBX phones and key telephone systems
If your company has over 40 employees, or if you demand advanced functionality from your phones, PBX systems are often the best solution. You may equate PBX phone systems with the massive telecom cabinets used by huge companies. While that still can be the case for large installations, the technology has progressed to the point where a powerful PBX for a small company can sit unobtrusively on a desk.

Most come standard with all the features you might want. In addition, they are totally programmable, so they can support the most complex implementations. You will likely pay a premium for this flexibility, but in many cases the price difference between PBX systems and less adaptable solutions will be smaller than you might expect.

If your company has 5 to 40 employee range, key systems are probably a better solution. This type of phone system uses a central control device called the key system unit (KSU) to provide features that are not available with ordinary phones. For example, a central unit typically allows users to make calls to another in-office extension, and prevents other users from accidentally picking up a line that is being used. Modern key systems also come standard with most features a business would expect - but in some cases they are less customizable.

While there are technical differences between a key and PBX phone system, the distinctions to a user have become relatively blurred. Many key systems include features that were once available only on PBXs, and some systems operate internally as either a key or a PBX depending on the software that is installed. The term "hybrid" is often used to describe systems that resemble both key and PBX systems.

Both key and PBX telephone systems require professional installation and maintenance. All outside telephone lines must connect to the KSU or PBX cabinet, as well as all inside extensions. Unfortunately, configuring and wiring these phone systems can be nearly as costly as the phones themselves. You will almost always be able to use existing phone wiring, but unless the phones you have are relatively new, they may not be compatible with the central unit and you will need to purchase new telephone handsets. One advantage of Inter-Tel’s Axxess phone system is the ease of upgrading.

KSU-less systems
If your company has fewer than 10 employees, you may be able to meet your telephone needs with a KSU-less system. For a much lower initial investment, KSU-less phones are designed to provide many of the features of a small business phone system in a decentralized manner. The phones themselves contain the technology necessary to allow them to communicate with each other without requiring a central cabinet.

KSU-less systems are not permanently wired into your office. These phones can easily be unplugged and moved to a new location or sold. This allows you to treat a KSU-less system much like any other business machine rather than as a permanent investment in your premises.

Make sure any KSU-less system you are considering is compatible with the type of telephone wiring used in your office, as well as accessories such as answering machines and modems. Because they are so inexpensive, KSU-less systems are not usually sold or supported by telecom vendors - you will need to do the shopping, installation, programming, and maintenance yourself. And they are also more susceptible to "crosstalk," a problem in which separate conversations bleed into each other. With hybrid key systems dropping so far in price, KSU-less systems present more risk than they are worth for most businesses.
