Ethernet Over MPLS/DWDM

E-Line is a simple, powerful Ethernet private line service designed to increase operational efficiency and improve your return on investment. 

E-Line uses Ethernet over multi-protocol label switching (MPLS) over dense wavelength division multiplexing (DWDM) technology that combines the benefits of intelligent routing with the advantages of 100% committed bandwidth. Your business will see marked improvements along point-to-point connections to data centers, storage-area networking including disaster recovery and business continuity, Internet access and interconnections.   

Using E-Line offers many advantages over a traditional private line service. You get the same reliability you depend on with private line, but with greater return on investment from these features coupled with operational efficiency and reduced costs:

  • High-performance with dedicated bandwidth and fast response times
  • Simple to configure, operate, manage and change
  • Flexible and scalable with your choice of bandwidth from 5Mbps to 1,000Mbps
  • Efficiency at lower costs compared to other private line technologies
  • Faster delivery with extensive pre-provisioning of network resources
  • Standards compliant with MEF certification and MPLS traffic engineered network
  • Full support from the CenturyLink project implementation and account teams
