The Edge-Core portfolio of carrier solutions provides the flexibility and cost efficiency that service providers require to meet the growing demand for IP and Ethernet services. And because all new Edge-Core switches running EdgeCOS, Edge-Core's native operating system, are IPv6-ready, there is plenty of room for growth without the need for major capital reinvestment in the near future. This savings in capital expenses (CapEx) is also realized by the fact that Edge-Core's high efficiency, high performance aggregation switches minimize the need for extra Carrier Ethernet equipment, offering hardware features such as RJ-45/SFP Gigabit combo ports, SFP 1000 Mbps ports, dual power supply, and 10G XFP ports, and software features including support for IEEE 802.1w Rapid Spanning Tree protocol to ensure loop free networking, together with redundant links to the core network with rapid convergence.

To guarantee precise frequency resolution which subscribers of services such as Voice over Internet Protocol (VoIP), Internet Protocol Television (IPTV), Video on Demand (VOD), Guaranteed Committed Information Rate (CIR) for Service Level Agreements (SLAs), and cellular Internet and file sharing expect, select Edge-Core Carrier Aggregation and Carrier Access switches support the latest network timing protocols, Synchronous Ethernet (SyncE) and IEEE 1588v2. In each case, these protocols provide carrier grade accuracy that allows Ethernet to provide the same level of quality and reliability as legacy technologies for use in carrier class applications. Reliability is also the focus of support for G.8032 Ethernet Ring Protection Switching (ERPS), a failure recovery protocol for Ethernet traffic in a ring topology that also ensures there are no loops formed at the Ethernet layer.

Featuring Fiber Access, wavelength-division-multiplexing (WDM) Access, Copper Access, and layer 2 Access switches, the majority of the Edge-Core line of Carrier Access switches provide Gigabit Ethernet combo ports, SFP 100/1000 Mbps ports, 1000BASE-T ports, and support for IP clustering, which allows administrators to use a single IP address to manage a virtual stack of up to 36 switches, together with enhanced QoS features such as DiffServ, Priority queue scheduling, 802.1p, and ACL. In addition, select Carrier Access switches provide expansion slots and dual power for AC/DC. Operational expenses (OpEx) are reduced, as well, because Edge-Core is able to maximize customer cost-benefit ratios due to the use of innovative yet standards-based technologies, which help to simplify service provider operational models.

Edge-Core offers Carrier Access Customer Premises Equipment (CPEs) and gateways, which are located at the home or business of a customer and connect with a carrier's telecommunications channel(s) at the demarcation point. Differing only in their physical (PHY) layers, copper or fiber, these devices are ideal for Ethernet or Fiber to the Home (ETTH/FTTH), or Ethernet or Fiber to the Building (ETTB/FTTB) deployments, within 100 meters. The result is a minimum cost to deliver high performance triple play services for both home and business customers. Of course, like Edge-Core Carrier Aggregation and Carrier Access switches, Ethernet Operations, Administration, and Maintenance (EOAM) is built-in to handle discovery, link monitoring, remote fault detection, and remote loopback. Among specific protocols supported include IEEE 802.1ag for connectivity fault management, IEEE 802.3ah for Ethernet in the First Mile tools, and ITU-T Y.1731 for fault management and performance monitoring.

As part of Edge-Core's commitment to promulgating standards-based Carrier Ethernet technical specifications and implementation agreements to promote interoperability and deployment of Carrier Ethernet worldwide, the company is a member of the Metro Ethernet Forum (MEF). MEF is a global industry alliance comprising more than 150 organizations including telecommunications service providers, cable MSOs, network equipment/software manufacturers, semiconductor vendors, and testing organizations whose mission is to accelerate the worldwide adoption of carrier-class Ethernet networks and services. Edge-Core's Carrier Ethernet switches are currently undergoing MEF certification.
