CSDS - ISDN Primary Rate Interface (PRI)

Overview

Circuit Switched Data Services (CSDS) ISDN (Integrated Services Digital Network) PRI is a local exchange access service that creates a direct digital connection to a Verizon central office to provide voice, data, image, and video services on a single circuit or line. Customers avoid the need for individual dedicated circuits for different applications.

Benefits

• Control Costs. If a dedicated T1 is being underutilized, it may be cost effective to replace it with a PRI and route calls over the network rather than pay the entire cost of the T1.
• Disaster Recovery. Circuit switched capability can provide alternate paths in the event of an emergency. Protect the reliability of your communications with options for backup configuration.
• Host Computer Access. To access host computers, customers can use variable, large bandwidth for high speed data communications.
• LAN-to-LAN connection. Large bandwidth is essential for heavy graphics and data intensive applications (i.e., Computer-Aided Design (CAD)/Computer-Aided Manufacturing (CAM)).
• PBX Trunking Efficiency. Call-by-call service selection can reduce trunking requirements and allow customized time-of-day selection of service.

Features

• Flexibility. ISDN PRI gives you fast, flexible access to services such as direct inward and outward dialing, WATS, toll-free , and circuit switched data, providing clear, digital transmission for voice and data communications. Gain the flexibility of call-by-call service selection that increases trunking efficiency.
• Feature Rich. The call-by-call service selection and individual calling line identification capabilities offer a cost-effective, feature-rich method of local access for applications such as PBX trunking, host computer access, LAN-to-LAN connections, and videoconferencing. Increase call handling efficiency with calling line identification—a feature available even to PBX users. Benefit from planned enhancements like additional telephone number capability.
• High Speed. ISDN PRI transmits large volumes of data, video and enhanced voice communications requiring higher transmission capabilities such as videoconferencing.
• Video Conferencing. Large bandwidth enables quality video resolution and allows for faster screen refresh. Save on travel expense by using videoconferencing with full motion virtual meetings.
