Role – Determines whether the ODU functions as a master or slave. In a link, one
side must be set to Master and the other side must be set to Slave (required for
link synchronization). Default value is Auto, meaning the role is set automatically
by the link.
side must be set to Master and the other side must be set to Slave (required for
link synchronization). Default value is Auto, meaning the role is set automatically
by the link.
Manually setting the Role is necessary only for asymmetric configurations.
Link ID – unique Tx and Rx Link IDs for links installed on the same site to avoid
locking on the wrong transmitter.
locking on the wrong transmitter.
Link IDs must be identical on both ends for the link to be operational.
ARQ - checkbox to enable the mode and field to view the current status.
The ARQ (Automatic Repeat Request) is an algorithm that uses selective repeat
(retransmission) to eliminate radio BER. The default mode is Enabled. When
both sides are enabled and radio link is up, ARQ status will be Established.
(retransmission) to eliminate radio BER. The default mode is Enabled. When
both sides are enabled and radio link is up, ARQ status will be Established.
Disabling the ARQ mode is not recommended as it may result in radio BER.
Lowest Modulation – Lowest modulation profile. When modulation drops below
this threshold, radio link will be down. It is used to limit the minimal modulation
profile of the link. Default QPSK 1 (lowest available).

This section allows configuring the following parameters:
RF Loopback – checkbox to enable the internal RF loopback, set the timeout for
clearing the loopback in seconds and select the modulation the ODU will be
tested at.
clearing the loopback in seconds and select the modulation the ODU will be
tested at.
Note that it will take the ODU to stabilize after loopback up to 3 minutes so set the
loopback timeout accordingly (recommended 600 seconds).

Mute remote transmitter first to avoid interference with the loopback operation.
Loopback is done with MAC addresses swap.
Refer to the Diagnostics chapter of this manual for detailed description of the
system’s loopbacks.
