5.3.2 | ISDN remote nodes |
With the remote nodes method, as shown
in Figure This method offers many advantages. It is the most secure and flexible, and it is the most scalable. Only one PC is required for the remote user, and many client software solutions are available. The only additional hardware required at the remote location is a modem. The main disadvantage of this method is the additional administrative overhead required to support the remote user. Because of its many advantages, this solution is used in the remainder of the design examples in this chapter. The full-time telecommuter/teleworker
is one who normally works out of the home. This user is usually a
power user who needs access to the enterprise networks for large
amounts of time. This connection should be reliable and available at
all times. Such a requirement would generally point to ISDN as the
connection method, as shown in Figure
