ISDN PRI: A Flexible Solution for Voice and Data

Do your communications services adapt to the way you do business? Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) provides a cost-effective solution for clear voice and high-quality data traffic that lets you allocate network resources in a flexible way that makes the most sense for your business.

ISDN PRI is a high-speed connection that uses 100-percent digital trunks to support your business's need for voice, data, and video, as well as Internet and remote LAN access. It connects your digital PBX or other digital premises equipment directly to the reliable AT&T network over ISDN-configured T1 facilities.

A reliable, all-digital switched network solution that streamlines communications and helps you save money.

Allocate network resources dynamically with ISDN PRI

Because the amount and type of network traffic needed can vary from hour to hour, ISDN PRI allocates bandwidth where and when you need it most. You don't have to designate certain channels for how you want to use them. For instance, outbound trunks aren't idle while inbound trunks are nearing capacity. ISDN PRI allocates your bandwidth automatically for each transmission on a call-by-call basis.

Surf the Internet, take an incoming call or fax a document all at the same time. ISDN PRI can eliminate the need for extra POTS (plain old telephone service) lines as well as dedicated voice or data access lines.

Control costs while improving quality

By integrating voice and data services on a single trunk line, ISDN PRI can help you reduce the expense of multiple lines without sacrificing quality. Having more bandwidth at your disposal helps make it possible to communicate with more customers, make more sales and process orders more quickly.

You can use ISDN PRI for virtually any combination of voice, video or switched data transmissions - whatever best supports your budget and business needs.

Consider

If you are considering an ISDN PRI solution for your business, here are some things to discuss with your AT&T representative:

What kind of calling services does your business need?

ISDN PRI offers dependable connectivity for local and toll calls, including long distance, international voice, video and switched data services. It supports inbound and outbound calling, as well as access to toll-free services.

How important is efficiency?

ISDN PRI helps improve the calling experience and your efficiency with faster call set-up times inherent in ISDN signaling. It offers trunks as Direct Inward Dial (DID), Direct Outward Dial (DOD), or DID/DOD combined.

The number of channels used for specific types of calls can be predefined, or traffic can be managed on a call by call basis. So whether it's voice, data, or video, ISDN PRI can help maximize your network's efficiency.

Will you need overflow management?

Your ISDN PRI network can be designed to accommodate overflow if a circuit is busy. Calls will be routed to another location, potentially saving you money by eliminating the need for additional circuits, and helping you avoid missing important calls.

Is your current network experiencing capacity issues such as busy signals or lack of an available line to make an outgoing call?

ISDN PRI can help you maximize the use of your network facilities, reducing busy signals and increasing outgoing call path availability.
