PBX In selecting a telephone system, there are many considerations to be made. Among these considerations are the size, scope, features, functionality, interoperability, maintenance, reliability and upgradeability, all in addition to cost and vendor selection play major roles in determining which type of system will best fit the needs of the company. Interoperability with voice mail and electronic messaging systems, PCs, LANs, video and multi-media servers and wireless systems are vital and important considerations going forward. Also important are the interfaces to Ethernet, coax or fiber used to access LANs, data equipment and local voice, wide area voice, and data network services; such as T-1, Frame relay, ISDN, and ATM. A PBX (private branch exchange) is a telephone system within an enterprise that switches calls between enterprise users on local lines while allowing an enterprise to share a certain number of external phone lines. The main purpose of a PBX is to save the cost of requiring a line for each user to the telephone companys central office. The PBX is owned and operated by the enterprise rather than the telephone company.4 Originally, such systems required the use of a live operator. Since almost all PBXs today are automatic, the terms PBX and PABX (private automatic branch exchange) are interchangeable. Today, PBXs use digital technology. That is possible because PBXs have evolved through four generations. The first generation used analog technology. It was also very basic as far as features and technology. The second generation introduced stored-program control processors. The third generation was the first to support end to end digital transmission, and uses both digital and analog proprietary telephones. The fourth generation is not clearly defined. However, it does employ LAN interfaces to provide a highway for interconnecting data devices. 2 A PBX includes: * Telephone trunk lines that terminate at the PBX. * A computer with memory that manages the switching of the calls within the PBX and in and out of it. * The network of lines within the PBX. * Usually, a console or switchboard for a human operator.4 Many medium sized or larger companies use a PBX because it is much less expensive than connecting an external telephone line to every telephone set in the organization. Also, its easier to call someone within a PBX because the number needed to dial is typically 3 to 4 digits. The PBX system that I have chosen to present is the Bizfon 680.
