The counters displayed in the fourth basic errors screen are the following:
•
CRC ERROR: indicates the total number of CRC errors that occurred during the test.
•
CRC E. R.: indicates the rate between the number of CRC errors and the total CRCs
transmitted.
•
E-BIT: indicates the total number of CRC errors detected by the remote device during
the test.

The TSW200E1 furthermore evaluates the ITU-T Rec. G.821, G.826, and M.2100.

The user can choose the analysis to be displayed, placing the cursor appropriately and
pressing <F3> (ENTER).
The G.821 analysis has corresponding parameters for each of the counters: BIT ERROR,
FAS ERROR, CRC ERROR and E-BIT. These counters are displayed in absolute or relative (%)
modes. The screens that are displayed depend on the chosen configuration. Choosing certain
configurations cause the screens that show the FAS and bit errors to be the only ones displayed.
The screen with the Rec. G.821 counters is shown below. There are screens like these for
FAS, CRC and E-BIT errors. They are accessible by using <F4> (NEXT) function key.
