The implementation of 2BASE-TL in the Metro Ethernet Copper Access solution from Hatteras Networks gives carriers both the rate and reach needed to deliver business-class metro-Ethernet services. MECA enables carriers to serve up nearly 20 Mbps of bandwidth via the local loop at customer serving areas distances of up to 12,000 feet. With MECA, carriers can Take Ethernet the Extra Mile™ to reach 100% of business customers in the CSA.

The MECA implementation satisfies all carrier requirements for outside cable plant, spectral compatibility and more. The access network can be a hostile environment for sophisticated switching equipment, and most traditional Ethernet vendors are unaccustomed to the stringent temperature, power, space and interface requirements imposed by carrier facilities—from controlled environmental vaults (CEVs) to remote terminals (RTs). Similarly, the importance of spectral compatibility cannot be underestimated in the access network. To be carrier-class, any new service delivery technology must operate within the standard spectral band plan to avoid any adverse impact on existing services.
