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
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 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
