reliability

This seems just as unreliable as DSL or T1s - is that true?
Mid-Band Ethernet solves the reliability issues that have plagued the deployment of traditional DSL and T1/E1 services. The access network has historically been the weakest link in the delivery of services - with 80-90% of service outages being directly related to problems in the access network.
Mid-Band Ethernet delivers a resilient business-class service by aggregating multiple copper lines into a single Ethernet interface. If there is a problem on one access line, the other lines will remain operational and continue to deliver service. The service reliability increases with each aggregated line. With many carriers bonding as many as eight pair to deliver a service, the reliability of Mid-Band Ethernet compared to traditional technologies can be increased by orders of magnitude.
You can compare the Mid-Band Ethernet approach with traditional DSL and T1/E1 pretty easily. In most cases, T1/E1 is delivered over two access lines, and if either line has a problem, the entire service is down.
Mid-Band Ethernet uses multiple access lines to increase reliability, not decrease reliability as in a T1/E1. With DSL, there is generally no resiliency - one line, one single point of failure. And when using technologies that are easily susceptible to variable noise like radios or electromagnetic interference, the situation can be very unstable.
Mid-Band Ethernet is more resilient to such outside plant noise.
And finally, Mid-Band Ethernet can be delivered with carrier grade equipment that focuses on SLAs for a quality experience for the enterprise customer. Mid-Band Ethernet is not residential DSL out of your every day Internet DSLAM. Mid-Band Ethernet needs to be delivered from carrier Ethernet equipment that is focused on QoS, reliability, services, and Ethernet service flexibility, so that the business customer receives the value and benefit of metro Ethernet - all without the expense of fiber deployment.
