To build the network, you must
select equipment for various company sites. Equipment needs vary by
site. The Figure illustrates common remote solutions that are used
to build a remote-access network. Typical site router considerations
and their needs follow.
When dealing with the central site, you will
learn how to connect necessary components to allow WAN connections
such as Frame Relay and ISDN PRI connections to the branch office.
You will also see ISDN BRI and asynchronous connections to the
telecommuter site.
The central-site router must have the
following interfaces:
- PRI interface for ISDN PRI and
asynchronous calls service unit (CSU/DSU) (If you are in North
America, you must provide the CSU/DSU)
- Modem for asynchronous calls
- Serial interface for Frame Relay
connections
- Ethernet connection to access
resources on the central-site LAN and connect to the
Authentication, Authorization, and Accounting (AAA) server
When installing a branch-office router, you
will learn how to identify and connect the necessary components to
allow WAN connections such as Frame Relay and ISDN BRI connections
to the central-site router.
The branch-office router must have the
following interface:
- Serial interface for Frame Relay
connections
- BRI interface for ISDN BRI
When providing for a telecommuter site using
routers such as a Cisco 700 series, you will learn how
to identify and connect the necessary components to allow a WAN
connection such as ISDN BRI to the central-site router. You will
also learn how to configure a mobile user with a PC and a modem to
allow an asynchronous connection to a company site router. The
telecommuter site must have the following interfaces:
- PC and modem for asynchronous
dialup calls
- BRI interface for ISDN BRI
You also need to work with your service
provider to make the proper connections into the provider’s
network. Your lab will connect to equipment that will simulate a
service provider’s network.
