manually.  Please  make  sure  one  channel  is  connected  to  the 
UCM6200 and in idle status before starting the detection. During the 
detection, source channel will be used as caller and send the call to 
the  configured  Destination  Number.  Users  will then  need  follow  the 
prompts in web GUI to help finish the detection. 
The default setting is "Auto Detect". 
 
 
 
-------------------------------------------------------------------------------------------------------------------------- ------------------ 
  Note: 
  The PSTN detection process will keep the call up for about 1 minute. 
  If "Semi-auto Detect' is used, please pick up the call only after informed from the web GUI prompt. 
  Once the detection is successful, the detected parameters "Busy Tone", "Polarity Reversal" and "Current 
Disconnect by PSTN" will be filled into the corresponding fields in the analog trunk configuration.
