Voice Solution Overview

What is EPABX

EPABX stands for Electronic Private Automatic Branch Exchange. It is a telephone exchange system used within an organization to manage internal communication and connect with external telephone lines. EPABX systems are commonly used in businesses, offices, and large institutions to handle multiple incoming and outgoing calls while also facilitating internal communication between extensions.

Key features of EPABX include:

  1. Internal Calling: Employees can call each other using internal extensions without the need for an external phone line.
  2. External Calling: The system connects the internal lines to external telephone networks, allowing calls to be made and received from outside the organization.
  3. Call Routing: EPABX can route calls to specific departments or individuals based on extensions, making it more efficient.
  4. Automated Features: Modern EPABX systems may have features like voicemail, automatic call distribution, call forwarding, and interactive voice response (IVR) systems.
  5. Cost Efficiency: Since internal calls don’t require external lines, they are cost-effective compared to using traditional phone lines for all communication.
  6. Scalability: EPABX systems can scale as an organization grows, adding more extensions or handling more external lines.

EPABX has evolved from analog systems to digital and IP-based systems, providing greater flexibility and integration with other communication technologies.

What do FXS and FXO Mean?

When FXS and FXO refer to the two types of ports used by the POTS (“Plain Old Telephone System”). POTS is an analog system using twisted copper wires; it was the only type of telephone system offered until around 1988, when ISDN, cellular, and VoIP services began to be offered. Although analog phone systems are no longer as prevalent as they once were, they are still widely used in situations when other technologies are either unavailable or not costeffective.

FXS/FXO connections are mainly used in phone line extensions, which is the context in which we will be discussing them.

 

FXS (Foreign Exchange Subscriber) is the port that delivers POTS service from a phone company’s Central Office within the PSTN (Public Switched Telephone Network) to devices such as analog phones and fax machines. In other words, it is a wall jack that points away from the Central Office to the subscriber, or end device. The FXS interface delivers dial tone, ringing voltage, and battery power to FXO end devices.

 

FXO (Foreign Exchange Office) is the port on the subscriber device that receives the analog line. The FXO interface points away from the device towards the Central Office and receives the POTS service from the Central Office. That is to say, it connects office devices like fax machines, modems, and analog phones to an outside telephone line via an FXO port on the device. For this reason, these end devices are often referred to as “FXO devices.” The FXO interface delivers an on-hook/off-hook loop closure.
