SHDSL EFM Access Device With Voice Support
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.
