Loopback Testing

The IE-MultiWay includes Loopback testing functionality. This feature is selectable
via iView2 within the OAM AH configuration. The menu of choices for all ports
includes:

•

Terminate/initiate

•

Process/ignore

OAM Loopback is controlled by using the “Loopback” and “Ignore Rx” control
parameters. Selecting “Initiate” from the “Loopback” control tells the client to start a
loopback process with the peer. Selecting “Process” from the “Ignore Rx” control
tells the client to process received loopback commands.

Only AH “Active” units can send a Loopback command to a remote unit. Either
Active or Passive AH units can respond to a Loopback command, but must be
configured to process these commands or they will be ignored.

Select Loopback to display loopback data and define how loopback is configured:
