What is an ISDN PRI?

Reading Time: (Word Count: )

Most businesses today are still using the outdated technology of old-fashioned analog telephone lines, but things are changing fast. ISDN PRI, or Integrated Services Digital Network Primary Rate Interface, offers the speed of a T1 line without the expense and inconvenience that comes with dozens (or hundreds) of physical land lines. What’s more, it integrates seamlessly with existing systems, so customers, vendors, and remote employees can dial in as normal using any kind of telephony. The people you communicate with do not have to have the same system in order to reach you.

How it works

ISDN PRI transmits voice and data in digital format over your internet connection. Twenty-three channels keep everything moving smoothly at 64 Kbps, so everyone in your office can get things done without interruption. Another channel is dedicated to transmitting signal information. This channel maintains contact with the carrier to ensure constant, reliable service. The channels are consolidated to one line connected to your PBX or network, simplifying access to many different services, including voice, data transfer, and fax.

Maximizing your network

Switching to a digital connection offers a number of benefits. It’s an economic solution to a larger office with a variety of internet and communications needs. As a general rule of thumb, if there are 10 or more people in your office, an ISDN PRI will provide all the connectivity and data transfer you need at a significantly reduced cost.

If your needs exceed 23 lines, your network is scalable.  By linking multiple trunks together, PRI can provide as much bandwidth as you need. And by consolidating your services, you’ll save on long-distance and traditional phone fees, while enjoying crystal-clear digital transmission for both incoming and outgoing communications. Plus, the use of dynamic call-by-call service features may reduce the number of lines you need simply by allocating data transmission protocols for maximum efficiency.

Why the cost difference?

With a traditional telephone setup, Specific trunk lines are assigned to each network service, and because dedicated lines are necessary, you pay the highest rate allocated for peak use. Transmitting over the internet allows for more flexible allocation of data transfer assets…and as a result, lowers the cost of service. There are no mysterious hidden fees, no long distance charges, and no need to give up a phone line to send and receive faxes. Your service is always on, and your prices are in line with actual calling patterns.

Making the move

The good news is, depending on your system, you may be able to keep and integrate much of your existing equipment. Upgrading to a better, cheaper option without a learning curve for your employees or the cost of a whole new setup for each office, and unlike purchasing a whole new telephone system, no additional training is necessary. Your staff won’t miss a beat. Or a client call.
