Typical Application

I. In this application, the Orion 4500 provides the ability to deliver multiple services by separating traffic into two scalable channels within a full or subrate T3 or E3 link.

II. The Orion 4500 reduces network complexity and operating costs while increasing the reliability of high-speed full and subrate T3/E3 service delivery. As a dual-port demarcation point between the network and customer premises, it increases the visibility or critical high-speed networks and saves the cost of implementing dual devices to support multiple data sources.
