PRI Gateway Solution Provider for Telecommunication Business

Do you remember the costly old PBX phone systems that were once the standard for businesses? The ones that sounded and seemed to have been built in the late 1960s? It was not an easy task to connect such an old system to the analogue phone network. An interface known as PRI, or Primary Rate Interface, served as a solution back then. Companies can send up to 23 calls at once over a single T1 line thanks to PRI. Compared to earlier choices that required separate lines for each call, this was a significant improvement.

For many years, PRI was the only acceptable method for companies to configure their phone networks, often known as trunks. Then everything changed with Voice over Internet Protocol (VoIP). Even though PRI is currently regarded as legacy technology, there are still certain specialized applications for businesses using outdated hardware. AKOM technologies provide a PRI gateway with multiple ports that can be utilized and customized through or by the user.

What is PRI and how does it work?

Primary Rate Interface is referred to as PRI. It is a kind of digital phone line used to link public switched telephone networks (PSTN) and commercial phone systems. Multiple speech and data connections between two physical places are carried out using PRI. Instead of analogue landlines, it provides digital access using the Integrated Services Digital Network (ISDN) protocol. It is generally used by business phone systems in places like contact centres, companies, hotels, and hospitals that need to handle large numbers of concurrent calls and dependable voice/data services. Businesses might gain from a PRI in comparison to many analogue lines by having more call capacity, faster data transmission, integrated voice or data, and reduced costs.

Characteristics of a PRI Line

Two pairs of copper wires, one for the service provider (network) and one for the client (business end-user) make up a PRI line in the PRI gateway. Although IT is only one line in theory, it may send 23 different messages at once (voice, data, or video.) As a result, up to 23 employees in your firm can communicate by phone, instant message, or video chat at the same time. A PRI's channels may each transmit data at a speed of 64 kbps. In PRI gateway lines are compatible with both IP PBX systems and analogue or hybrid EPABX configurations. Two private branch exchange (PBX) systems can be connected via a PRI.

The Functions of PRI

There are two varieties of the PRI circuit—the physical connection that links your phone system—T1 and E1. Though there are certain technological distinctions to be aware of, the primary distinction between the two PRI circuits has more to do with location:

Direct inward dialling (DID) is made possible by PRI, allowing a third party to contact an employee directly by calling their direct number. An organization simply needs a small number of physical phone circuits to support several employee direct phone numbers. As an illustration, a single PRI gateway with 23 accessible channels would be able to accommodate up to 50 direct workers. This is effective since it is improbable that every employee will be on call at the same moment. Additional PRI gateway can be installed to increase capacity as a business expands. Hence, a second CIRCUIT may be installed to increase the capacity to 46 calls if the first PRI gateway is completely utilized with 23 simultaneous calls.

When PRI is compared to older analogue phone systems, it is more affordable and scalable due to its modular expansion capability. For enterprises, PRI offers an effective and adaptable digital phone solution. Numerous staff can direct numbers while using fewer physical circuits thanks to the shared channels. By adding extra PRI circuits as needed, capacity may be readily increased.
