Toshiba 2000-series ユーザーズマニュアル

The Emergency Ringdown or Hotline Service feature enables standard telephones to 
automatically ring a designated extension by going off-hook. Digital telephones 
cannot perform this feature, but they can receive Emergency Ringdown or Hotline 
Service from standard telephones.

Emergency Ringdown is used in healthcare facilities, where it 
is used to assist callers who may not be able to complete a call 
by dialing. An example of an incoming Emergency Ringdown 
call is shown on the right. The calling [DN] and “Ringdown” displays whether soft 
keys are ON or OFF.

This same feature is also known as Hotline Service and is often used for telephones in 
hotel/motel lobbies.

This feature enables you to set your telephone so that you and people near your 
telephone can hear the called party over the speaker, but the called party can not hear 
you. You can alternate between parties as long as the handset is off-hook.
