ISDN Bit Error Test
The 965DSP-B will count and display the number of Near-End and Far-End errors.
“Near-end” errors are the errors detected at the 965DSP-B. “Far-End” errors are errors detected at an ISDN line card. (The far-end count is transmitted to the 965DSP-B over the ISDN link.)
The screen displays the elapsed time since the start of the ISDN Error Test. Standard practice is to monitor the line for a fixed period of time (5 or 15 minutes) and count the number of errors.
The 965DSP-B will automatically stop counting errors after 15 minutes.
The word “Link” will be displayed as long as the 965DSP-B is linked to the ISDN line. If the link is lost, the screen will display “No Link”.
Press the [Enter] key to start the test again.
