EPABX

EPABX has proven to be of immense use in communicating within office, making routine work simpler. It can be defined as a switching system for calls that enables both internal as well as external switching functions in an organization. Typically up to 10,000 subscribers can be accommodated by a single EPABX system. 

Components of EPABX:

• Internal switching network.
• Microcontrollers and microcomputer for arbitrary data processing for control and the logic.
• Logic cards, switching and control cards, power cards and related devices to facilitate operation.
• Stations or telephone sets, sometimes called lines.
• External Telco trunks that deliver signals to and from the EPABX.
• Console or switchboard allows the operator to control incoming calls.
