Chapter 4 Logging in Using Modem

4.1 Introduction

The administrator can log into the Console port of a remote switch using a modem
through PSTN (public switched telephone network) if the remote switch is connected to
the PSTN through a modem to configure and maintain the switch remotely. When a
network operates improperly or is inaccessible, you can log into the switches in the
network in this way to configure these switches, to query logs and warning messages,
and to locate problems.
To log into a switch in this way, you need to configure the terminal and the switch
properly, as listed in the following table.
