DZS – ETHX-32XX – EtherXtend Access Device

  • Full VLAN support with priority and QoS
  • Automatic load balancing on bonded EFM ports for optimum throughput
  • Units operate in back to back mode (CO and CPE mode)
  • Environmentally hardened for use in extreme conditions or remote cabinets (DC Models)
  • Up to four SHDSL EFM ports
  • Remote Management – Web GUI, SNMP and ZMS CPE Manager


Zhone’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 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.

These EFM access devices also have models that include either 4 or 8 voice ports. The ETHX-3244 has four voice ports, and the ETHX-3248 has eight voice ports. Each of these models has four Ethernet ports that can be configured for bridging or routing. All Ethernet ports support full VLAN priority and QoS.
