Promina systems cost effectively consolidate a variety of user traffic and applications on a single platform. The Promina platform adapts to support time division multiplexing (TDM), frame relay, integrated services digital network (ISDN), asynchronous transfer mode (ATM) and Internet Protocol (IP) transport techniques. While leveraging the bandwidth-on-demand (BoD) benefits of frame and cell-based solutions, Promina can configure and maintain quality of service (QoS) guarantees for optimal application transport.

Other key features include:

• Standards-based connection of existing equipment - voice, data, video, and fax - through a broad range of user-side interfaces.
• Intelligent operating system software that adapts to avoid any single point of failure, improving network reliability and simplifying network management across all Promina system nodes.
• System operation and service capacity changes without interruption via scalable Promina system modules.
• Cost-effective, non-disruptive migration path to broadband services.
