Impacts and Recommendations

  • U.S. Ethernet access provides a better price per Mbps than traditional TDM, saving enterprises money and gaining capacity for comparable expenditures
  • Optical Ethernet access provides faster speeds, and more consistent and predictable end-to-end performance than legacy TDM access for enterprise applications
  • Ethernet access provides enough bandwidth to support the performance of jitter- and latency-sensitive applications, so enterprises can often eliminate MPLS CoS in the WAN
