PurePacket Overview

PurePacket is a multi-service packet-based access system that enables competitive carriers to offer differentiated services and combine voice/data on new generation IP-based networks, as well as traditional circuit switched infrastructures. This complete access solution includes customer premise equipment, central office aggregation devices (for central office, co-locations and points of presence), and an operations management system for network control and services management. To guarantee QoS, enable Class of Service (CoS), and maximize the traffic carrying capacity of access networks, PurePacket uses an MPLS-based architecture to route, transport and switch voice and data transmissions in packet format.
