Connect the instrument as displayed on the screen and 
press the RIGHT CURSOR key.  
The status line indicates the status of the test.  
The central part of the screen automatically gives information on the line voltage and 
line current.   
When you use the 2B1Q line code, the bottom lines give the activation and de-
activation time. These times are automatically calculated when you have connected 
the instrument for the first time to the line and made a call.  
 
Start measuring the binding resistance of the U interface.  
The LED RUN goes on and the test results appear on the screen.   
 
 
3.8. Acting as Loop Box 
 
The ACT AS LOOP BOX function allows to automatically answer to incoming calls 
and loop the corresponding B channels.  
You can also set up the LOOP BOX to perform a compatibility check on incoming 
calls based on the profile and the Own/MSN value set in the Common Setup menu. 
In this case only compatible calls will be accepted. Incompatible calls will be rejected. 
By default this mode is automatically active in the background when other tests are 
performed. It is used to perform BER tests in auto call mode, § 0, or where an 
instrument with automatic answering is necessary.
