Office Telephone System Types

One of the most widely used forms of telecommunication system today is the phone system. While most are aware of its use, few are familiar with its details, features and operations. This results in improper installation and therefore leads to ineffective use.

Telephone System, Equipments and Functions
Typical office phone system components includes the main distribution or switching equipments, software application, telephone station set and trunk lines. Advancement in IT (Information Technology) and telecommunication technology in the past decades has introduced modern equipments that added to the expansion of today’s modern telephone systems. Moreover, these latest innovations led to the significant development of quality communication.

Telephone System Types
Despite of these improvements, the major concept of the phone system not been altered. In fact, phone systems can be categorized in different types which include key systems and PBX.
  • Key System – It was 60 years ago when this type of telephone system was introduced. With its root stemming to the technology of the electro-mechanical, its most obvious feature is the use of keys or buttons designed to allow a user to quickly connect to a phone line. Modern key systems are purely electronic in nature and make use of a microprocessor to further enhance its functions.
  • PBX (Private Branch eXchange) – Early PBX systems are comprise of basic components namely common control, network/terminal interface, phone stations, switching matrix, and transmission media. Its evolution from human operated switchboard to computer-controlled circuits has made it a cost-effective solution for business communication. Unfortunately, some of its equipments are notably bulky which can also take up precious office space.
  • Virtual PBX / Hosted PBX / IP-PBX – Continuous research and development have paved the way for a much better alternative to the aging PBX phone system. These modern systems are the fusion of computer, internet and mobile technology. Utilizing these systems does not require the purchase of expensive hardware since all the components are hosted on the provider’s premise.
