Manually setting the Role is necessary only for asymmetric configurations.
Transmit Asymmetry
– Default value is symmetric configuration: 50% for Tx
and Rx (
50tx-50rx
). For an asymmetric configuration (75%/25% or 90%/10%),
you will have to manually configure the Role and set the Master unit to
75tx-
25rx (or 90tx-10rx)
and
the Slave unit to
25tx-75rx (or 10tx-90rx)
. Default
value is
50tx-50rx
.
Mode
– Select one of the following operation modes:
-
Alignment
– Carrier Wave transmission. Used for antenna
alignment.
-
Adaptive
– Adaptive Bandwidth, Code, and Modulation.
-
Static
– Fixed modulation profile. If you select
Static
, you must
select from a list of pre-configured modulation profiles in the
Modulation
field.
Default value is
Adaptive
.
Modulation
– qpsk, 16QAM, or 64QAM.
Sub Channels
– From 1 to 4 (occupied bandwidth. For Channel Width
250MHz: 62.5-250MHz, For Channel Width 500MHz: 125-500MHz)
Repetitions
– 1,2 or 4
FEC Rate
– 0.5
When using the system in Static mode, you must select from a pre-defined list of
modulation profiles. In Adaptive mode, the ODU will switch among the
modulation profiles from this list.
To check the available modulation profiles, refer to
Viewing Modulation Profiles

Tx and Rx Link ID
–You can set unique Link IDs for links installed on the same
site to avoid locking on the wrong transmitter.
Operational Status
– Displays the radio link status (Up or Down).
Tx and Rx State
–Displays the Tx and Rx chains status.
RSSI (dBm)
– Displays the Receiver Signal Strength Indicator.
CINR (dB)
– Displays the Carrier to Interf Noise ratio, which
indicates the radio link’s signal quality. In normal conditions, CINR≥17
indicates a good signal quality.
Tx Power (dBm)
–ODU’s transmit power (+5 to -35dBm).
Adjust Tx Power so the RSSI at the remote end will not be higher than -35dBm
(overload threshold).
Tx Mute
– set to
Enable
to mute the transmitter
Tx mute Timeout (seconds)
– number of seconds for Tx mute enabled
