TAILIEUCHUNG - Ethernet Distribution Frame Centralized Cross-Connect System for Managing Ethernet Data Services

Ethernet-based data services offer the opportunity to create differentiation, command premium pricing, and earn higher margin for such value-added data services as transparent LANs, storage area networks, and virtual private networks. 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. | Ethernet Distribution Frame Centralized Cross-Connect System for Managing Ethernet Data Services application note Situation Ethernet-based data services offer the opportunity to create differentiation command premium pricing and earn higher margin for such value-added data services as transparent LANs storage area networks and virtual private networks. 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 cord connections on the front of the EDF cross-connect bay. This craft-friendly .
