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
What does Convergence mean?
Convergence is the merging of voice, data and often video onto
a single network. Most often that network is a company LAN with
enough bandwidth to accommodate all users and QoS or Quality of
Service control to ensure high quality voice and video transmissions.
What is PBT?
PBT stands for Provider Backbone Transport. It's an adaption of
Ethernet to extend Layer-2 switching into the WAN transport network.
PBT was pioneered by Nortel and will be standardized by the IEEE
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 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
