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 QoS and how do you
QoS means Quality of Service. Most often you hear about QoS when
referring to converged networks that transport both packet voice
and data. QoS mechanisms may include prioritizing voice packets
over data because voice is much more affected by latency and jitter.
What is Mid-Band Ethernet?
Mid-Band Ethernet is a WAN or Wide Area Network technology that
delivers 2 to 45 Mbps over existing copper pair wiring. This bandwidth
range falls neatly in between T1 lines at 1.5 Mbps and DS3 service,
usually provided over fiber optic carriers, at 45 Mbps. As a native
Ethernet delivery system, mid-band Ethernet offers an easy way
to extend the corporate network beyond the premises.
