The Emergency Ringdown or Hotline Service feature enables standard telephones to automatically 
ring a designated extension, after the ringdown timer expires, by going off-hook.

The Hotline Service feature is often used for telephones in hotel/motel lobbies. This same feature is 
referred to as Emergency Ringdown in healthcare facilities, where it is used to assist callers who may 
not be able to complete a call by dialling.

Electronic and digital telephones cannot perform this feature, but they can receive Hotline 
Service or Emergency Ringdown from standard telephones.

➤

If your station is idle or busy on a call while another station tries to contact you, the calling station can 
turn on the message waiting LED on your telephone. Your Message Waiting lamp flashes when there 
is a message. 

Up to four message waiting indications can be left at a station at any one time.

➤

Lift the handset off-hook. 

The designated station will automatically ring after the 
ringdown timer expires.

If a valid feature access code or DN is dialled before the 
ringdown timer expires, automatic ringdown does not occur.

An example of an incoming 
Emergency Ringdown call to an 
electronic or digital LCD telephone 
is shown on the right. The calling [DN] and “Ringdown” 
displays whether soft keys are ON or OFF.
