For over 20 years the Promina multiservice access platform has been the backbone for some of the most important, mission-critical networks in the world. The Promina platform efficiently manages a network's bandwidth. Depending on the user traffic type, Promina can apply dynamic bandwidth allocation, frame relay switching, IP routing, ISDN signaling, or voice compression to maximize available bandwidth and minimize delay across a backbone network.

Promina incorporates an intelligent operating system that avoids any single point of failure, improves network reliability and permits system operation and service capacity changes without interruption. Each node contains an up-to-date view of the network topology and operates independently. This allows the network to automatically reroute traffic within milliseconds in the event of a failure. For maximum fault tolerance and network reliability, Promina systems may be easily configured with redundant power, memory, common logic and port interfaces.
