Still trying to troubleshoot the Sl 2100 dropped call issue . talking to NECNTAC he suggested "In truth the only ways to test / monitor this are to be on-site with a T-BERD or Sunset T10 and monitor the circuit , alternately some CSU's ( ADTRAN TSU 100, 120 etc..) have the ability to capture / print to file error logs, that indicate errored frames per second, LOS, CRC. etc... "
I see Don suggested a CSU , so would a CSU help me here ? if so which one ? I don't have access to T-Berd of Sunset T10
