In today's
changing world of telecommunications and technology, we must
quickly adapt to speed. Today getting information faster and
more effectively means more profits. Therefore, it is imperative
that we first understand the importance of technology and how
speed and efficiency can ultimately affect our bottom line.
 DSL
Digital Subscriber Line (DSL) is a method of sending and receiving
information mostly through the internet. This information travels
from point to point a lot more quickly than through regular phone
lines, and a lot less cheaper than using T-1 service. This is
a perfect fit for small to large businesses that need to access
information and deliver information more quickly. The only downside
is that DSL is for the most part distance sensitive. When you
are outside a three-mile radius then speed of the service becomes
a problem, and so carriers usually will not offer the service.
ISDN
Integrated Service Digital Network (ISDN) is a public standard
sending voice, data or packets over the public switched telephone
network. It is a dial up service, but a version of ISDN stays
connected is available as well. This is called Always On/Direct
ISDN. Telephone companies also charge usage fees by per minute
or flat rates for a set of minutes each month. This is a good
application when you cannot get DSL in your area.
T-1's
T-1 service allows 24 voice or data calls on two pairs of copper,
fiber, infrared or microwave. When T-1's became first available
to businesses in the early 80's, only large corporation could
afford to use. Now it is a common service used by both small
and large businesses. The use of multiple T-1's such as T-3'
s (28 T-1's) are also common in large organizations for multiple
tasks. T-1's are more expensive than DSL, but depending on the
application a company may need the use of T-1 service.
Frame Relay
Frame Relay is a network access service by which a local or long-distance
runs a shared network by multiple users.
This is a virtual or private network, which is used as an alternative
to building one's own private network. Frame Relay is best used
by companies with multiple locations and those that need to communicate
private information with other companies.
ATM
Asynchronous Transfer Mode (ATM) is a high speed switching service
capable of carrying voice, data video and multimedia images.
This service is mainly used in network service provider networks.
However, large companies can also use this application as well.
The key to this service is that it enables providers and end
users to carry multiple types of traffic without building separate
networks for voice, video and data communications. |
