Detailed Description
This heading contains:
•
A description of the feature-relevant signalling on the system terminals.
•
A definition of the scope within which the feature can be carried out.
•
Remarks, tips or information on the sequence of operation of the feature or on
exceptional cases.
Prefix and suffix dialling procedures
Features are controlled using procedures. A procedure can be triggered under
three different sets of conditions:
•
In prefix dialling: dialling takes place before any connection is made.
•
In suffix dialling: dialling takes place during a connection or call.
•
During the ringing phase: dialling takes place during the ringing phase of an in-
coming call
Depending on the nature of the feature a procedure is triggered either in prefix di-
alling, in suffix dialling, during the ringing phase or in several call states.
On system terminals, user-related features are activated or deactivated using the
Foxkey, under which a variety of functions can be stored. Equipment-specific set-
tings can be found in the relevant Operating Instructions for the terminals con-
cerned.
