Ethernet-based data services offer the opportunity to create differentiation, command premium pricing, and earn higher margins 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, all of these advantages can be quickly erased by a poorly designed cabling and connectivity architecture | Ethernet Distribution Frame Introduction Glide Cable Manager Patch Panel Introduction and Selection Tutorial Patch Panels High Performance Patch Cords Accessories 286 291 293 297 305 306 1 -952-938-8080 1 -800-366-3891 285 wo Ethernet Distribution Frame Introduction Centralized Cross-Connect System for Managing Ethernet Data Services MSO Market Solutions Situation Ethernet-based data services offer the opportunity to create differentiation command premium pricing and earn higher margins 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 all of these advantages can be quickly erased by a poorly designed cabling and connectivity architecture. An effective ethernet data services 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 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 semipermanent patch cord connections on the front
