Many types of WAN technologies can be
implemented to solve connectivity issues for users who need network access
from remote locations. In this chapter, you will learn
about the services, standards, components, operation, and
configuration of Integrated Services Digital Network (ISDN)
communication. ISDN is specifically designed to solve the low bandwidth
problems that small offices or dial-in users have with traditional
telephone dial-in services. Telephone companies developed ISDN with
the intention of creating a totally digital network. ISDN was
developed to use the existing telephone wiring system, and it works
very much like a telephone. When you make a data call with ISDN, the
WAN link is brought up for the duration of the call and is taken down
when the call is completed; it's very similar to how you call a friend
on the phone and then hang up when you are done talking.

Washington
Project: ISDN Connectivity
In
this chapter, you will learn the concepts and
configuration process needed to implement an ISDN
connection in the Washington School District WAN.
You need to provide an ISDN connection for a remote
site that needs part-time connectivity to the
district.
