Created by Nortel spin-off Elastic Networks, EtherLoop (a.k.a next generation DSL) is Ethernet over standard twisted pair (POTS ) technology that allows for simultaneous voice and high-speed data communications. Speeds range from 125 Kbps to 6 Mbps over distances of up to 21,000 feet.
Similar to Ethernet, Etherloop transmits data packets in bursts. Between bursts, EtherLoop looks for problems and interference in the lines and knows to steer clear and find an alternate path. Also, EtherLoop is Ethernet compliant, so it is easily adaptable to existing Ethernet systems.
EtherLoop also borrows from the best of DSL to offer point-to-point security and a non-shared medium (more users don't slow down connection speed), But unlike DSL, EtherLoop avoids impacting other services such as ISDN, T-1, ADSL, HDSL and SDSL, which are in the same cable binder group.
EtherLoop is not proprietary. Elastic Networks plans on licensing the technology to manufacturers who can design and create their own EtherLoop solutions.
