Pins and
Jumper Impedance
J6 1 and 2 for 120 ohm
2 and 3 for 75 ohm
Warning To prevent problems with the E1 interface and to reduce the potential for injury, jumper J6
should be installed by trained service personnel only. For either impedance option, a jumper installed
at J6 bypasses the AC-decoupling capacitor to ground, thereby coupling the interface directly to AC.
This is a setting that could pose a risk of severe injury. By default and for safety, J6 has no jumper
installed.
After you set jumper J6, proceed to the section "Removing and Replacing MIP Port Adapters" in
this chapter.
Using the EXEC Command Interpreter
Before you use the configure command, you must enter the privileged level of the EXEC command
interpreter with the enable command. The system will prompt you for a password if one has been
set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket
(>). At the console terminal, enter the privileged level as follows:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a
privileged-level password, as follows:
Router> enable
Password:
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is
not displayed.
Step 3 When you enter the correct password, the system displays the privileged-mode system
prompt (#) as follows:
Router#
Step 4 Proceed to the following section to configure the MIP controller.
Using the Configure Commands
Following are instructions for a configuration: enabling a controller and specifying IP routing. You
might also need to enter other configuration subcommands, depending on the requirements for your
system configuration and the protocols you plan to route on the interface.
The channel-groups must be mapped before the MIP controller can be configured.
For complete descriptions of configuration subcommands and the configuration options available,
refer to the Router Products Configuration Guide and Router Products Command Reference
publications, which are available on UniverCD.
Function
Controls capacitive coupling for either 120-ohm or 75-ohm operation. An installed
jumper directly connects the Rx shield to chassis ground.
