In the following example, the attendant dials the first digit (3) of the set directory number to be
called (3456, for example) on the keypad:
2.3.1 Reservation (locking) an internal user set
When an internal user number is dialed, the user set, if free, is reserved by the attendant
(becomes under attendant control). The user can still dial a number or access another service.
This reservation (attendant control) is indicated on the user set:
- By the symbol on the resource keys (multiline set).
- By the deletion of any entry on the screen.
The user set does not ring until the attendant presses the Ring (or Call) key.
This specific feature of the attendant set ensures the attendant can always reach the station
user. If the user picks up the receiver (off-hooks), the user hears the music-on-hold, indicating
that the set is reserved and that all outgoing calls are denied. When the attendant presses the
Ring key (or Call key) on the attendant set, it is automatically connected to the user.
If the user set is a multiline set, the user is not locked and can make calls. However, a set
resource is used for the incoming call from the attendant set.
