Data results
Table 13 provides descriptions of the test results in the Data category.
Round Trip Delay (ms)
Round Trip Delay, Avg (ms)
Round Trip Delay, Min (ms)
Round Trip Delay, Max (ms) Time in milliseconds between the transmission
and receipt of 16 consecutive bit errors in the RT-
Delay test pattern.
Avg
– The average round trip delay calculated in milli-
seconds.
Max
– The maximum round trip delay calculated in mil-
liseconds.
Min
– The minimum round trip delay calculated in mil-
liseconds.
Interval Block Error Rate Number of block errors divided by total number of
blocks analyzed in the defined test interval.
Interval Bit Error Rate Number of bit errors divided by total number of bits
analyzed in the defined test interval.
Pattern Losses Number of times pattern synchronization was lost.
Pattern Slips Number of times data bits were added to or
removed from the receive pattern.
NOTE: You must transmit a pseudorandom pattern
to observe pattern slips.
Total Blocks Number of blocks received after pattern synchroni-
zation has been achieved.

Test Result Description
Frame Error Rate Ratio of the number of characters received in the wrong
format to the number of characters received in asyn-
chronous timing mode.
Frame Errors Count of characters received in the wrong format since
the last test restart in asynchronous timing mode.
Parity Error Rate Ratio of the number of parity errors detected to the num-
ber of parity bits received in asynchronous timing mode.
Parity Errors Count of parity errors since the last test restart in asyn-
chronous timing mode.
Characters Received Count of the number of received characters since the
last test restart in asynchronous timing mode.
