1.4 Additional programmable keys
The Alcatel 4035 attendant set may be expanded with add-on keypad modules providing a
maximum of 60 additional programmable keys.
Two models are available:
- 20 keys: Alcatel 4090M
- 40 keys: Alcatel 4090L
Each key can be programmed as a resource or supervision key. Some of these keys may also
be locked by the system manager.
1.5 Soft keys (dynamic function keys)
1.5.1 Principle
These are keys SK1 to SK5 (SK stands for Soft Key), located below the set display. By
convention, keys SK1 to SK5 are numbered from left (SK1) to right (SK5).
Soft keys are dynamic keys are keys whose function is determined by the system according to
the current operating or programming status. They cannot be programmed by the user.
Keys SK1 to SK5 are mainly used for telephone operation. The operation is enabled in the
system when the label is displayed on the screen. The attendant can activate the feature by
pressing the key corresponding to the label.
Pressing a key for which no label is displayed has no effect; this helps avoid inadvertent
activation of features.
The dynamic keys are also used to:
- Implement operating features (callback, text messaging, etc.).
