6.5.1.5 Indoor Unit Loopback Controls
These controls allow you to set the loopbacks on the payload data.
• IU Loopback to Line - Used to loopback the data on the payload interface so
that incoming user payload data is sent straight back to the user. The payload
data does not go out over the RF link.
• IU Loopback to RF Link - Used to loopback the payload (Indoor Unit)/Outdoor
Unit data so that payload data arriving over the RF link is looped and sent back
across the RF link.
Perform a loopback as follows:
1. Select the Loopback Type by choice of arrows on the IU being tested.
2. Select the Loopback Timeout Time (in seconds). If enabled, the Loopback
state will cancel after Time seconds and the unit will return to normal operation.
3. Click on the Loopback Timeout Enable checkbox.
4. Click on the Apply Changes button.
