Detect Model 
Select "Auto Detect" or "Semi-auto Detect" for PSTN detection. 
  Auto Detect 
Please  make  sure  two  or  more  channels  are  connected  to  the 
UCM6510 and in idle status before starting the detection. During the 
detection, one channel will be used as caller (Source Channel) and 
another channel will be used as callee (Destination Channel). The 
UCM6510  will  control  the  call  to  be  established  and  hang  up 
between caller and callee to finish the detection. 
  Semi-auto Detect 
Semi-auto  detection  requires  answering  or  hanging  up  the  call 
manually.  Please  make  sure  one  channel  is  connected  to  the 
UCM6510 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". 
Source Channel 
Select the channel to be detected. 
Destination Channel 
Select the channel to help detect when "Auto Detect" is used. 
Destination Number 
Configure the number to be called to help the detection. 
  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.
