Technology Overview - EFM (Ethernet First Mile / Final Mile)
Hatteras Networks -Technology Overview
Recent advances in
technology now make it possible for carriers to deliver
high-speed Ethernet services over ordinary local loop copper
wiring. Most of these advances are evolutionary, some are
revolutionary. The major breakthroughs are in the area of
bonding, which is the technique used to combine multiple copper
pairs in a seamless fashion to deliver bandwidth incrementally
and on-demand. Some of the advances leverage existing Ethernet
provisions to enhance service differentiation in the
metropolitan area. And the remaining advances involve management
capabilities in the demanding carrier environment.
Hatteras Networks
supports all of these advances, and leads the industry. Which is
why the Hatteras Ethernet Service Edge solutions represents the
state-of-the-art in metro-Ethernet equipment for carrier
networks. No other solution available today in this space is as
powerful and flexible. Hatteras Networks Ethernet Service Edge
solutions are optimized for carriers seeking to grow revenues
and profits throughout the customer serving area - now and for
the foreseeable future.

Hatteras Networks - Advances On the Road to Ethernet over
Copper
Existing digital subscriber line (DSL) deployments depend on
asynchronous transfer mode (ATM), which substantially
complicates service delivery both to the premises and through
the backbone. To achieve higher data rates, Inverse Multiplexing
over ATM (IMA) is normally used to bond copper pairs. But IMA
bonding suffers from numerous limitations, such as when the
throughput of all pairs in the bonded group drop to the lowest
data rate of any single pair. In addition, the interworking
required to convert from Ethernet to ATM (and vice versa)
complicates operation and drives up the cost. Frame relay
suffers from this same extra layer of complexity.
Recognizing the inherent limitations of DSL over ATM and other
first/last mile solutions, the Institute for Electrical and
Electronic Engineers (IEEE) and the Ethernet in the First Mile
Alliance (EFMA) set out to standardize Ethernet over copper
wiring in the local loop. The effort resulted in publication of
an IEEE 802.3ah standard, joining the long list of other 802.3
standards that together govern all aspects of Ethernet.
