Sharing Business Broadband
Costs
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
as PBB-TE.
How does Spanning Tree Protocol
work?
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
loops.
What is 2BASE-TL?
The 2BASE-TL designation refers to an Ethernet over Copper delivery
technology offering 2 Mbps per copper pair over metropolitan area
distances from the central office equipment. It is part of the
Ethernet in the First Mile project, also known as IEEE 802.3ah.
This technology leverages existing copper phone line for native
Ethernet WAN services.
