Bandwidth to Support Convergence
Convergence means combining or converging voice, data and video
onto a single network. Enterprises usually need to expand their
LAN bandwidth and set up a QoS or Quality of Service priority
system to give priority to real-time streams such as telephone
calls or video conference feeds, which are more sensitive to network
delays than data transfers. Most often, the common protocol for
convergence is IP.
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.
Is Ethernet a Full or Half
The original Ethernet implementation was based on avoiding collisions
on packets all sharing the same network line. Small networks using
hubs are half-duplex. Switched Ethernet networks are full duplex
because the layer 2 switches prevent packet collisions.
What is PoE?
PoE means power over the Ethernet. It is a way to provide a DC
power supply over network lines to energize security cameras,
VoIP telephones, badge readers, wireless access points and other
devices that might not have an AC outlet nearby.
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.
