Zhone's EtherXtend 2-Port SHDSL EFM Ethernet Access Devices (EADs) allow Carriers, CLECs, ISPs and PTTs to deliver Ethernet services to their customers simply, quickly and cost-effectively over the existing copper plant. Intended for deployment at end-users' locations, these devices allow delivery of IEEE 802.3ah Ethernet in the First Mile (EFM) services using the latest in SHDSL standards. By supporting up to 5.7 Mbps over a single copper pair, each pair can carry 150% more bandwidth than competing products that rely on traditional G.SHDSL standards.
