Testing MCT1 Lines
While in dynamic mode, you can use the Configuration Manager to trigger MCT1
port actions to test the quality of the line. MCT1 line tests include
• Transmitting specific codes to the remote end of the MCT1 connection
• Introducing deliberate error patterns into the transmitted BERT (Bit Error
Rate Test) bit stream
All actions are MCT1 port-specific. For example, a send loopback action is
transmitted across a specific port; a BERT reset action resets the port-specific
series of BERT counters.
The BERT statistics show the results of your actions. You can view BERT
statistics using the Statistics Manager utility. For information on the Statistics
Manager, see Managing Routers and BNX Platforms.
Testing All Lines Associated with a Port
With all modules but QMCT1 modules, a line test affects all logical lines
associated with a port for the duration of the test. With QMCT1 modules, you can
choose whether to test all logical lines associated with a port or to test one
individual line.
Follow the instructions in this section all lines associated with a port. To test
individual lines for QMCT1 modules, refer to “T
esting Individual Logical Lines
(QMCT1 Only),” later in this chapter.
Setting the Test Parameters
Before you test the line, you must set the test parameters.
To set the test parameters:
1. Start at the MCT1 Logical Lines window (refer to Figure 6-14).
2. Click on Port Details.
The MCT1 Port Parameters window appears (F
igure 6-19).
