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 autocall mode (see Chapter 3.5) or 
when an instrument with automatic answering is necessary. 
You can make a return call (call-back) to the calling number. The B channel Status 
function displays call-back connections, if any (see Chapter 6). 
3.8.1.  Setting up a loop box test 
Define the following parameters to operate the instrument as loopbox: 
 
Call accept: Choose the control mode on incoming calls.   
•  Only Compatible, the loopbox function only accepts incoming calls 
compatible with the set profile.   
•  None, the loopbox function does not accept incoming calls at all, sending to 
the remote the disconnection cause 21 (Call Reject).  
•  All, the loopbox function accepts all incoming calls. 
Call-back: to activate the call-back function. The instrument can be set to generate a 
direct outgoing call to the calling number (CGN) for each incoming call. The function 
can be activated only if the calling number is determined. The outgoing call will be 
generated: 
•  After connection end, after the remote disconnection of the incoming call,  
accepted and connected in loop. 
•  After delivery end, after the remote disconnection of the incoming call, 
accepted (ALERTING), but not connected. 
•  None, never.
