Overview
Integrated Service Digital Network Primary Rate Interface (ISDN PRI) is a standard, all digital access technology
that allows for simultaneous, integrated voice and data capabilities over standard existing telephone lines.
ISDN PRI offers 100% digital clarity and an array of value-added features, such as calling number identification
and call-by-call selection, that enhance productivity.
ISDN PRI is configured with 23 bi-directional B (Bearer) channels and one D (Data) channel. Unique to ISDN PRI
is its ability to designate the D channel to handle all of the signaling and call control requirements and leave
the remaining 23 B channels free for any mix of voice, virtual private line and circuit-switched data.
With ISDN PRI, you can:
- Use your existing infrastructure to enable all digital, high-speed voice and data applications that increase productivity;
- Dynamically allocate channels to adapt to changes in traffic patterns and increase trunking efficiency by up to 30%, reducing total trunks required;
- Leverage advanced features to support call center applications, or to extend the life and value of an existing PBX system, while reducing call set-up and connection time by up to 90%;
- Cost-effectively connect multiple locations with guaranteed, two-way bandwidth that can carry voice and data, all via the PSTN;
- Transfer large volumes of data and enhanced voice over instantaneous connections with superior transmission quality; and
- Implement a cost-effective, robust disaster recovery/back-up solution to protect mission-critical traffic on a wide area network or traditional T1.

Increased Efficiency
- Each PRI can handle multiple voice, fax and modem lines simultaneously, reducing the overall number of trunks needed by as much as 30%.
- Dynamic Channel Allocation, a standard ISDN PRI feature, accommodates drastically changing traffic patterns by automatically allocating channels to support voice or data as required.
- ISDN PRI uses out-of-band signaling for faster call set-up, faster connections, and 64K clear channel capability.
Ultimate Flexibility
- ISDN PRI uses existing standard phone lines and fiber optic circuits, making it simple to add or change configurations. A single line can have multiple telephone numbers and ISDN PRI comes with enhanced voice features that help improve productivity.
- ISDN PRI's ability to dynamically allocate channels adapts to changes in business needs unlike the static designations in traditional T1 channels.
- ISDN PRI's range of standard features and capabilities are available for one low price, letting you take advantage of all the functionality you need and nothing you don't.
High Quality, Low Cost
- ISDN PRI offers 100% digital quality…And it does it for less using your existing infrastructure.
- ISDN PRI is four to eight times faster than a standard 28.8 Kbps modem and speeds are available from 64 Kbps all the way up to 1.544 Mbps.
- With its fast call-set up times and fast, error-free transmissions, ISDN PRI helps business improve productivity, improve service, and ultimately improve their customer satisfaction.
Sample Applications
- PBX-to-central office connections.
- Enable faster call set-up and Calling Line ID allows for faster response. PRI handles more calls, more quickly
- Use Video Conferencing comfortably with data and voice applications, using bandwidth on an as needed basis
- Provide remote access to the corporate network with analog modems or faster Basic Rate ISDN (BRI)
- High-speed Internet access is integrated with data and voice communications.
With PRI at the host end, Internet Service Providers can offer a better level of service affordably and efficiently
- Applications that transmit large amounts of data at irregular intervals utilize flexible bandwidth capabilities
- Dial backup links can be used if private lines go down
