Chapter 8, Programming the Call Processing Subsystem
Using the Call Processing Subsystem’s Remote User Interface
Using the Call Processing Subsystem’s Remote User Interface
In order to use the Call Processing Subsystem’s Remote User Interface, a mobile 
station must be powered on, and connected to the Test Set.
NOTE:
Option 004:Tone/Digital Signalling is required in an HP 8920A in order to use the Call
Processing Subsystem. Attempting to access the Call Processing Subsystem without
Option 004 installed will generate an “Option not installed.” error.
Connecting a Mobile Station
 shows a typical example of how to connect a mobile station 
to the Test Set. You may need a special fixture to access the mobile station’s 
antenna, audio in, and audio out signals. These fixtures are available from the 
mobile station’s manufacturer.
If any audio testing is to be done on the mobile station, the audio input 
(microphone input) to the mobile station and the audio output (speaker output) 
from the mobile station must be connected to the Test Set. If no audio testing is to 
be done only the antenna needs to be connected to the Test Set.
