Verilink DIU2130 -- TEST/MONITOR --

The Test and Monitor Block Error Counter function is used after a loopback has already been established. The loop might be in the local CSU, the network itself, or the far end DIU. When T1 or T2 is selected a test pattern is sent from the port indicated and the receive data is monitored for errors. The expectation is that the pattern being sent will be received unaltered, indicating a good path to the point of loopback.

To run a test and monitor results on port 1, enter T1.

To run a test and monitor results on port 2, enter T2.

A display appears like:


Port 1, Block Error Count 0,  (STOP) >
If the data pattern being sent is received with no errors the Block Error Count (BEC) will remain at zero. For any block in which a single bit error occurs the number will increment.

During a good test the STAT LED on the DIU for the port in test will be lit solid amber. If errors occur that LED will flash red to green.

To end the test just press the ENTER key. Be sure to also end whatever loop may have been used.
