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.
Where does a VPN make sense?
A VPN or Virtual Private Network is a security technique to allow
public networks, like the Internet, to be used for secure private
data transmission. Since Internet access is almost universally
available, using VPN software to encrypt data into private tunnels
is more cost effective than building a fully meshed network to
connect many locations.
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 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
