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.
How does Spanning Tree Protocol
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
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.
