CSTA Interface 
 

Definition  
By selecting an application ID, the station can address the associated CSTA application if this application has already been registered with the HiPath system. A registered application can address a station independently (e.g. to confirm an action on the display).
An I/O session can be started using a feature code or a function key. An I/O session can be started, resumed and stopped with the function key; the function key LED indicates the status of the I/O session (ready, active, interrupted).
During an I/O session, the station can operate the application with the aid of the navigation keys, dialing keypad, plus/minus keys, alphanumeric keypad, programmable keys and softkeys (CMI).
