The administrator can log into the console port of a remote switch using a Modem
through public switched telephone network (PSTN) if the remote switch is connected to
the PSTN through a Modem. 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 trap messages, and to locate problems.
To log into a switch in this way, you need to configure the administrator side and the
switch properly, as listed in the following table.
