PABX SYSTEM

PABX SYSTEMS

Short for Private Automated Branch Exchange, this telephone network is commonly used by call centers and other organizations. PABX systems allows a single access number to offer multiple lines to outside callers while providing a range of external lines to internal callers or staff.

Some manufacturers of PABX System(PBX) systems distinguish their products from others by creating new kinds of private branch exchanges. Rolm offers a Computerized Branch Exchange (CABX) and Usha Informatics offers an Electronic Private Automatic Branch Exchange (EPABX).

A PABX System includes:

• Telephone trunk (multiple phone) 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

• A console or switchboard for a human operator (optional)

In some situations, alternatives to a PBX include centrex service (in which a pool of lines are rented at the phone company's central office), key telephone systems, and, for very small enterprises, primary rate Integrated Services Digital Network (ISDN) , PBX System, Pbx Solutions
