Wake-on-ring
Encyclopedia
Wake-on-Ring sometimes referred to as Wake-on-Modem (WOM), is a specification that allows supported computers and devices to "wake up" or turn on from a sleeping, hibernating
or "soft off" state (e.g. ACPI
state G1 or G2), and begin operation.
The basic premise is that a special signal
is sent over phone lines to the computer through its dial-up modem, telling it to fully power-on and begin operation. Common uses were archive

, although hobbyist use was significant.
Fax
machines use a similar system, in which they are mostly idle until receiving an incoming fax signal, which spurs operation.
This style of remote operation
has mostly been supplanted by Wake-on-LAN
, which is newer but works in much the same way.
