PBX Phones Key Terms


Since many medium and large businesses use Private Branch Exchange (PBX) telephone networks, it's vital to know and understand the key terms related to these types of phone systems. PBX phones provide outside lines without the cost of having an external telephone line hooked up to every phone system in a business. Users can transfer incoming calls throughout a company or make outgoing calls to more than one phone line at a time. There are many key terms used to describe and explain the various functions and types of PBX phones. Take the time to learn them so that you can provide your employees with information about PBX phones and maintain an efficient business.

Integrated services digital network (ISDN) systems

Integrated services digital network systems are the global communications standard for sending voice, data and video over telephone lines. ISDN is one of the services that users of PBX phones can select when creating their business phone system.

Voiceover Internet Protocol (VoIP)

Voiceover Internet Protocol, or VoIP, is a type of PBX phone system that uses the Internet to transfer calls. Using VoIP services allows users to make phone calls without additional charges beyond their monthly Internet access billing.

Central office exchange (Centrex)

Centrex is a type of PBX phone system that switches calls from a local or centralized phone system instead of through a telephone company. Centrex users can select the services they want including call transfer and three-way calling for their PBX phones.

Interface module

An interface module is a terminal connector or switchboard that connects components to a central system. Businesses that use voice mail, fax machines and modems can integrate services and promote productivity.

Digital

A digital phone system uses digital transmission technology to convert audio files into digital or binary codes. Digital technology offers PBX users clearer sound than analog systems.

Analog

Analog transmissions are the original method for transferring voice and data. It uses one continuous signal to transfer information, but it is generally not as clear as a digital transmission. Many PBX phones have the ability to use both digital and analog methods.
