The PBX Evolution
The term PBX refers to a Private Branch Exchange. A PBX is sometimes called a telephone switch, business telephone system or phone switching device. The term PBX is synonymous with Electronic Private Automated Branch Exchange (EPABX) and Private Automated Branch Exchange (PABX). It is similar to a central office exchange but usually much smaller and privately owned. A central off exchange can accommodate 10,000 subscribers. PBX systems are typically designed to accommodate from 10 to 10,000 subscribers or extensions. A PBX is like a central office exchange for a single building of cluster of buildings. A PBX can handle many phone lines into or out of a particular location. Most advanced PBXs can facilitate both voice lines and data lines, route calls to other offices and to the public telephone network. With a PBX in place, each phone only needs an extension, not a phone number, and the PBX handles all calls made between individuals within the company.
The primary intent of a PBX is to route incoming calls to the appropriate extension within the office and to share a group of phone or “trunk” lines between extensions. When an outside call is required, an access number is dialed (example “9”) to access an outside trunk line. The PBX then transfers the call to the phone company’s Central Office. The telephone company then forwards the call to the desired number in the outside world.

Telephone Systems and Communication
One of the most important tools in any business is the telephone and you would be surprised if I told you how many entrepreneurs write business plans and leave out the cost of their telephone systems. It is kind of amazing when you think about it, you would have a very tough time running a business without a telephone, can you imagine even trying?
An interesting note to this subject is that generally over half of the business plans I read leave out the telephone system as a start-up cost? They do not even budget in going down to a thrift store or to a garage sale to buy a phone? You need a robust phone system if you want to get your business into the big league.
