Testing MCE1 and MCT1 Interfaces
This chapter describes how to use the Configuration Manager to test single-line
and multiline MCE1 and MCT1 circuits in the following sections:
•
About the Tests
• Setting Test Parameters
• Running Port Tests
• Testing Individual Logical Lines (QMCT1 Only)
About the Tests
While in dynamic mode, you can use the Configuration Manager to trigger port
actions to test the quality of MCE1 and MCT1 lines. Tests include
• Transmitting specific codes to the remote end of the MCE1 or MCT1
connection
• Introducing deliberate error patterns into the transmitted BERT (Bit Error
Rate Test) bit stream
BERT statistics show the results of your test actions. You can view BERT
statistics using the Statistics Manager utility. For information on the Statistics
Manager, see Managing Routers and BNX Platforms.
Note: Except for the QMCT1 module, all test actions are port-specific. For
example, a BERT reset action resets all port-specific series of BERT counters.
When testing ports on a QMCT1 module,
