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

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. 

Each EtherXtend device provides 4 Ethernet ports for connection to

cutomer equipment. The EtherXtend SHDSL EFM products are available

in 1-port, 2-port, and 4-port SHDSL 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 using the standard data rates. These units also support the extended

rates which will allow up to 12 Mbps on each SHDSL link. The lower

speeds have been extended also. The unit can be configured for as low as

32kbps, which greatly extends the distance that can be achieved. 

As with all of Zhone'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. The units can be also used in a back-to-back mode with one

unit acting in the CO mode, and the other unit in the CPE mode. 

Zhone'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.
