After reaching a busy station or a station with the Do Not Disturb (DND) mode set, you can set 
Automatic Callback (ACB) to have the system call you back when the called station is no longer busy 
or in the DND mode. Automatic Callback does not apply to outside calls.

4. Dial a telephone number if you 

entered the code after accessing the 
Exchange line

...or resume talking or hang up if you 
entered the code during the call.

1. After reaching a busy 

station, press 

4

.

You hear busy tone, followed by dial tone (2 secs.), then 
busy tone.

2. Hang up.

You can make other calls while waiting for the called 
station to become available.

3. Your telephone rings at a fast 

rate when the called station 
becomes idle.

4. Answer within three rings to 

prevent the callback from 
being cancelled.

You hear ringing, as if making a regular internal call. If 
you used Voice First instead of Tone Signalling, you  hear 
a single tone.

If you hear busy tone after answering, it means the called 
party has already received or originated another call. Your 
request is not cancelled. You will be called again when the 
station becomes idle.

5. If you were attempting to 

make an outside call and did 
not use LCR, you must now 
redial the telephone number.

If the original call was made using LCR, the telephone 
number is automatically dialed.
