Connect To The Network - METRObility Optical Systems Delta Class Installation And User Manual

Remote Loopback Switch (RLBK)
The remote loopback switch allows you to test the fiber connection between
a Metrobility Delta Class "twister" and a remote Metrobility x133 unit.
Enabling the switch sends a loopback request to the remote fiber port. To
run the loopback test properly, the following conditions must be met:
• The remote unit must be a Metrobility x133 standalone converter or
line card.
• The DSLB switch on the remote unit must be disabled.
If the conditions are satisfied, the remote loopback sequence will begin.
The remote fiber port will go into loopback mode. Next, the local "twister"
will generate a test pattern that is sent to the remote unit and then looped
back. The local "twister" will read the returned data to verify proper
transmission. The LB LED on the local "twister" will indicate whether the
test passed (green) or failed (amber). Refer to
further information.
If the two conditions for remote loopback are not met, the remote loopback
test will always fail. By default, remote loopback is disabled.

Connect to the Network

The Metrobility 100Mbps Delta Class "twister" offers the ease of plug-
and-play installation. The overhang extension provides built-in protection
for the two cable connectors.
When making network connections with the Metrobility "twister", grasp
the end of the cable with your index finger on the top of the connector
and your thumb on the bottom, as shown in the illustration below. For
easier installation, insert the copper cable to the "twister" before connect-
ing the fiber.
