Medical Imaging Transmission
Medical images, such as those generated by Teleradiology equipment,
have large file sizes due to high resolution. Rapid transmission
between hospitals and medical centers requires high availability,
high bandwidth telecommunication services. For smaller offices
or infrequent use, a T1 data line might easily suffice. For medium
and larger facilities, DS3 or Ethernet fiber optic carriers are
recommended.
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.
Is Ethernet a Full or Half
Duplex system?
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.
How does Spanning Tree Protocol
work?
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
loops.
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.
