CenturyLink Ethernet Network Solutions

Get All the Right Connections

Select the right Ethernet connectivity options to build and support your performance network. CenturyLink offers metro and national cost-effective Ethernet options to handle all of your business applications.

Metro Ethernet

Metro Ethernet service combines the power of Ethernet and optical technologies across metropolitan area networks (MANs) to provide low cost, scalable and secure bandwidth. Metro Ethernet provides local area network LAN-to-LAN connectivity between two or more customer locations within a metro area. Our Metro Ethernet solution is based on distributed Layer 2 switching and shared transport data bandwidth, and is suitable for data applications.

E-Line is a national and metro Ethernet private line service that connects customer sites within and between major metro markets across the United States. It uses Layer 2 Ethernet with dedicated bandwidth in granular steps from 5 to 1000Mbps. It meets the business challenge of eliminating inefficiencies by transporting business-critical information between multiple customer sites and data centers at low latency in point-to-point or point-to-multipoint configurations. E-Line increases return on investment as an economical service that’s still suitable for demanding enterprise applications.

E-Line Technical Specifications

E-Line uses Ethernet over MPLS over a non-oversubscribed dense wave division multiplexing (DWDM) network.

It delivers a marked improvement along point-to-point connections to data centers and storage-area networking including: disaster recovery, business continuity, Internet access, peering and meet-me interconnections. After E-Line is configured for multiplexing (multiple virtual circuits per port from one location routed to other E-Line locations), you can have hub and spoke multi-site connections within or between any E-Line market.

Using E-Line offers many advantages over a traditional private line service. You get the same reliability you depend on with private line. Plus, you also get increased choice of bandwidth granularity, improved operational efficiency, reduced cost and greater flexibility that all together offers increased return on investment.
