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.
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
What is QoS and how do you
QoS means Quality of Service. Most often you hear about QoS when
referring to converged networks that transport both packet voice
and data. QoS mechanisms may include prioritizing voice packets
over data because voice is much more affected by latency and jitter.
What is Mid-Band Ethernet?
Mid-Band Ethernet is a WAN or Wide Area Network technology that
delivers 2 to 45 Mbps over existing copper pair wiring. This bandwidth
range falls neatly in between T1 lines at 1.5 Mbps and DS3 service,
usually provided over fiber optic carriers, at 45 Mbps. As a native
Ethernet delivery system, mid-band Ethernet offers an easy way
to extend the corporate network beyond the premises.
