COMSPHERE 6800 Series Network Management System

Modem Bit Error Rate Test (mbert)

(Disruptive)

Use the mbert command to locate primary data channel problems on a COMSPHERE device's facility. This is done by calculating the bit error rate. Once this test is started, it continues to run until this command is executed again and abort is entered as an option, or until the Abort command (abort) is sent to the device to stop the test.

For most commands, NMS enables you to specify the destination for the command's results and schedule its execution. If the last page of the input form cannot accommodate the Destination for results and Schedule execution fields, an additional page is provided. For a complete description of these fields, refer to Chapter 1, Introduction.
