You may log in your switch from its console port from a remote device across a PSTN
with a pair of modems in between. When your switching network fails, this allows you to
remotely configure your switch, retrieve logs and warning messages, and locate the
problem.
To log into your switch in this way, you need to configure the terminal and the switch
