Extending native 10/100Base-T and Gigabit Ethernet services across the LAN, WAN, and MAN means data services are less expensive to deploy, provision quickly, and offer exceptional reliability and security. Yet as the Ethernet distribution system grows with more routers and switches in central offices, all of these advantages can be quickly erased by a poorly designed cabling and connectivity architecture. As service providers move from being vendors of T1, T3 and OC-XX data pipes to partners providing value-added Ethernet data services, an effective business model includes the following goals: • Create a flexible, carrier-class Ethernet delivery system, and • Decrease operating costs of Ethernet delivery. Reaching these goals is contingent largely upon building the correct architecture to support Ethernet data services. Solution Achieving the dual requirements of lower costs and carrier-class services is possible by creating a centralized cross-connect patching system with an Ethernet Distribution Frame (EDF). An EDF provides a cross-connect field that ties together all Ethernet network elements from multiple floors of the central office (CO) or point-of-presence (POP), providing a common craft interface for performing adds, upgrades, and rearrangements on Ethernet services. In this simplified architecture, all network elements have permanent equipment cable connections that are, once terminated, never handled again. Technicians isolate elements, connect new elements, route around problems, and perform maintenance and other functions using semi-permanent patch application note cord connections on the front of the EDF .
