Ensure that no errors or alarms are present on the transmission system because this will impact the measurement. The measurement will be triggered by an Alarm Indication Signal (AIS) The TX300/e measures how long the AIS event remains present after the event is first recognized and will continue to measure the total disruption time in the event of multiple disruptions.

  • Page 391 TX300S_e-manual_D07-00-064P_RevA00 BERT Testing Tips A BERT samples every incoming bit and looks for something that doesn't occur often. This traditional method typically used in SONET/SDH measurements, can however take a very long time. For example, in a 1Gbps Fiber Channel system, errors occur on average once every 1000 s –12 (about 17 Min) for 1x10 BER, so you would need to detect at least 10 to 100 errors before you...
  • Page 392 TX300S_e-manual_D07-00-064P_RevA00 FC-2 Header Format The Frame Header is the first field of the frame content and immediately follows the SOF delimiter. The Frame Header is used to control link operations and device protocol transfers as well as detect missing or out of order frames. The values of each field can be edited depending on network setup and test scenario.
