Zhone EtherXtend Gateway Appliance

Zhone's EtherXtend SHDSL EFM Ethernet Access Device (EAD) allows 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, this device allows delivery of IEEE 802.3ah Ethernet in the First Mile (EFM) services using the SHDSL standards. By supporting up to 13.6 Mbps over a single copper pair, each pair can carry significantly more bandwidth than competing products that rely on traditional G. SHDSL standards.The unit supports EFM loop bonding, thereby enabling up to 54 Mbps over four copper pairs. Because this is an EFM product, the loops can be at different rates, and still be part of the EFM bundle. This access device is equipped with an autorate capability that allows the unit to run at the maximum line rate supported by the copper loop. This autorate feature greatly simplifies installation and service provisioning.Typically, the MXK at the central office is used with the EtherXtend EFM endpoints. However, the EtherXtend endpoints (without voice) can also work back to back without the MXK.
