Telecommunications System Equipment

Telecommunications system equipment generally falls into two categories: key phone systems and PBX systems. The two systems are used in the same way, but their difference lies in their use of telephone lines and the number of people they are intended to serve. Key phones were designed for use by small businesses, while PBX phone systems are meant for large workplaces.

PBX systems use an internal switchboard that directs calls within the company. This switchboard also offers users direct dial options. Key phone users, on the other hand, must first find an unoccupied line before making external calls. Key phones also display every phone line on all stations.

More about PBX and Key Systems

Both PBX and key phone systems are push-button phone units that contain a variety of features, such as the classic conferencing, transferring, and hold with background music features. Caller ID is a standard feature these days, displayed on LCD screens that vary in size--though the larger screens are preferable. Another important feature, call pick-up, allows calls to be redirected to other phones. This is a feature that comes in handy, for example, when you know you'll be away from your desk and would like another person in your group to answer your calls.

Phone systems for today's busy workplace must have highly programmable voicemail capabilities as well. Callers must of course be able to leave messages. However, today's voicemail systems offer even more options. For instance, the paging feature alerts you to new voice messages, and call return allows you to automatically return the call of the person who has left you the voice message.
