If the requested feature is not available for any reasons, Reorder Tone will be heard. Otherwise the neces-
sary actions are as described in the following examples.
1. CALL BACK: Access Code = 2
When the called busy station’s number has been dialled and Busy Tone received, dial “2” and listen for
Service Set Tone (SST).
Replace the handset and wait for recall when the party becomes free.
Note: The standard limitation of only one Call Back per calling station applies. Further attempts will
return Reorder Tone. (ROT)
