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.
How is PoE used for IP Phones?
PoE or Power over Ethernet is a standard that defines a way to
transmit electric power to network devices as well as information
packets. When PoE equipment is installed in equipment lockers,
an IP telephone gets its power from the network and does not need
a separate AC power supply.
What's the difference between
MAN and WAN?
MAN stands for Metropolitan Area Network. MANs are set up to provide
broadband network connections within a city or metropolitan network.
WAN means Wide Area Network, a term applied to any network outside
the control of the enterprise. A MAN is a limited case of WAN.
What is a Service Level Agreement?
An SLA or Service Level Agreement is often part of the contract
between a business and telecom carrier for line services such
as carrier Ethernet.The SLA spells out the expected availability
of the line service and what penalties the carrier is liable for
if the line doesn't perform as stated.
Will Carriers "Light Buildings"?
Some will if their closest point of presence (POP) is within a
mile or so of your location. The farther away you are, the higher
the bandwidth commitment needs to be in order to justify the carrier's
