DZS EtherXtend EFM Ethernet Access Devicezhone etherxtend 3000

SHDSL.bis EFM (IEEE 802.3ah) Ethernet Access Device

ETHX-3014, ETHX-3024, ETHX-3044


DZS's EtherXtend 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.

The EtherXtend SHDSL EFM products are available in 1-port, 2-port, and 4-port configurations. The 2-port and 4-port units support loop bonding, thereby enabling up to 11.4 Mbps transmission rates over two copper pairs, or 22Mbps over four copper pairs. As with all of DZS's EtherXtend product family, these products share some common attributes - enhanced performance in a streamlined, low-cost architecture, designed for ease-of-use, rapid deployments, and low-density applications.

At the Central Office, the MALC can be used with the EtherXtend EFM endpoints.

DZS's line of EtherXtend EFM access devices are built for reliability and resiliency: dynamic and proactive performance monitoring ensures the quality of bonded groups; seamless failure recovery and hitless adds and drops ensure maximum uptime; a hardware platform designed for a carrier environment.
