Step 4 To configure a T3 line, enter the following command:
mgx8830b.2.PXM.a > cnfln -ds3 <bay.line> -len <LineLength> -clk <clockSource>
-lt <LineType> -oof <OOFCriteria> -cb <AIScBitsCheck> -rfeac <RcvFEACValidation>
Table 3-2 lists the parameter descriptions for configuring lines. Be sure to use only the parameters listed
for T3 lines.
Step 5 To verify your configuration changes, enter the dspln command.
Configuring E3 Lines
At the physical communications level, you can configure the Transmit clock source for E3 lines. The
following procedure describes how to configure E3 lines.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2 If you do not know the line number you want to configure, enter the dsplns command to display a list
of the lines.
Step 3 To display the configuration for a line, enter the dspln command.
mgx8830b.2.PXM.a > dspln -e3 1.1
Remember that you cannot configure a line until you have brought it up with the upln command, as
described in the “Bringing Up Lines” section earlier in this chapter.
Step 4 To configure an E3 line, enter the following command:
8mgx8830b.2.PXM.a > cnfln -e3 <bay.line> -clk <clockSource>
Table 3-2 lists the parameter descriptions for configuring SONET, DS3 and E3 lines. Be sure to use only
the parameters listed for E3 lines.
Step 5 To verify your configuration changes, enter the dspln command.
Verifying Line Configuration
To display the configuration of a line, use the following procedure.
Step 1 Establish a CLI management session at any user access level.
Step 2 If you do not know the line number you want to view, display a list of the lines by entering the following
command:
mgx8830b.2.PXM.a > dsplns
