And with rate potential in excess of 100 Mbps, 10PASS-TS can serve the highest
bandwidth applications over shorter distances.
For those carriers already delivering services via ATM-based digital subscriber line
(DSL) technology, Mid-Band Ethernet provides a path to simpler networks with lower
operating expenses and to differentiated, higher-margin services currently out of reach
using existing technologies. The simplicity and cost-effectiveness of Ethernet yields immediate
savings in capital and operating expenditures. Subscribers connected to the
network with 1000BASE-X Gigabit Ethernet and Mid-Band Ethernet experience the
same service and are managed with the same paradigms and the same software??”it??™s
all Ethernet; the only difference is the access media and the available bandwidth.
The EFM copper standards leverage the best DSL layers, as defined by the
International Telecommunications Union (ITU), as the physical layers for Mid-Band
Ethernet. By utilizing these existing standards, IEEE 802.3ah benefits from the high
volume of DSL chipsets while significantly improving upon the original silicon by defining
new and efficient mechanisms for Ethernet transport.
