To put the remote module into Smart Loopback or DTS RFC 2544
mode:
1. Select the Remote Capability as Remote Loopback or DTS RFC 2544.
2. Select the Loop Up or Connect button to respectively enable the Smart
Loopback or start the DTS RFC 2544 mode on the target module. An
icon will be displayed in the title bar if the operation is successful.
3. For Remote Loopback, any test/tool can be started at this time.
For DTS RFC 2544, only the RFC 2544, Ping and Trace Route tests/tools
can be started.
4. Select the Loop Down or Disconnect button to respectively disable the
Smart Loopback or DTS RFC 2544 mode from the target module.
Loop down or Disconnect is possible only following a successful loop
up or disconnect process on a selected target module.
Note: Even if a remote module is busy, it can still be overtaken by the Loop Up or
Connect command.
