Sharing Business Broadband
Even smaller businesses can have high performance dedicated Internet
access by splitting the cost of a fiber optic Ethernet connection
with other businesses in their building or business park.
What is Ethernet over Copper
Ethernet over Copper, or EoC, uses copper transmission lines rather
that fiber optics. T1 lines are most often used to transport mid-band
Ethernet signals in the 1 to 10 Mbps bandwidth range when provisioning
fiber optic lines is too expensive.
What is PBT?
PBT stands for Provider Backbone Transport. It's an adaption of
Ethernet to extend Layer-2 switching into the WAN transport network.
PBT was pioneered by Nortel and will be standardized by the IEEE
How does Spanning Tree Protocol
STP or Spanning Tree Protocol is a technique used by Ethernet
switches to ensure that there is one and only one physical path
from source to destination. This is done to prevent forwarding
What is the Cost Advantage
of Carrier Ethernet
Where available, Ethernet transport services from competitive
carriers may cost less than half the lease price of DS3 service
for over twice the bandwidth. The difference in cost between SONET
optical carrier service and Gigabit Ethernet WAN service is even
