Illinois Telephone Demographics
Market Service Areas (MSAs) or Local Access
and Transport Areas (LATAs) define MSA 02
‘communities of interest’ that may be served
by one or more local telephone companies. To call or MSA 04
connect a data circuit from one MSA to a location
in another MSA requires the services of a MSA 01
long distance provider such as Sprint,
AT&T, or MCI.
MSA 03
MSA 06
Illinois has 15 major MSAs. The ICN has
established at least one point of presence (POP)
in each of these MSAs. A POP is a secure
and environmentally managed MSA 17
room where the ICN maintains and MSA 05 MSA 07
manages a variety of telecommunication
equipment such as routers and ATM
switches. Schools, libraries, and other MSA 09
entities do not have to purchase service
from a long distance carrier in order to MSA 10
connect to the ICN. This saves ICN MSA 08
constituents a considerable amount of money.
A state provisioned circuit from one MSA to
another is, for education, typically around $1,600
per month. A circuit within an MSA is around $500
per month. MSA 15 MSA 11
The ICN aggregates traffic at the POP before passing
it to the next POP or to the Internet. In this way,
many entities can utilize the same set of circuits for
Internet access. This set of circuits which connect the
ICN POPs together and to the Internet is called the MSA 12
ICN network backbone.
The ICN backbone network is managed out of Springfield. The
Illinois Department of Central Management Services operates a 24
hour, 7 day per week Network Operations Center where network
problems are reported and resolved. ICN technical staff constantly
monitor the network to insure that traffic is moving through all parts of the backbone efficiently.
There are over 50 telephone companies operating in Illinois. Ameritech ( ) has approximately
70% of the market while GTE ( ) has approximately 70% of the land mass. McLeodUSA ( ) is
the 3rd largest company with Gallatin Rivers ( ) being the fourth. All the white areas are small
independent telephone companies.
