o
Checkbox to enable the ATPC operation.
o
ATPC Target RSSI – allowed values -35 to -70 dBm (default -35 dBm).
o
ATPC Min Tx Power – allowed values -35 to 0 dBm (default -35 dBm).
o
Min CINR – allowed values -128 to 128 dB (default -128 dB).
Encryption – checkbox to enable Encryption and field to enter the static key.
The EtherHaul supports 128bit and 256bit AES encryption with Static key. This
means that the encryption key (32 characters long for AES 128bit or 64
characters long for AES 256bit) must be inserted manually into both ends of the
link. If there is an encryption mismatch, traffic does not go over the link.
Encryption is a licensed feature that requires license for operation. Before
configuring it, verify that license is available and enable the
encryption
license
component.
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.
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%), Role
has to be set: the Master unit transmits the higher rate (75tx-25rx or 90tx-10rx)
and the Slave unit the lower rate (25tx-75rx or 10tx-90rx).
Note: Asymmetric configuration depends on product’s specs and is relevant only
for TDD systems).
Link ID – unique Tx and Rx Link IDs for links installed on the same site to avoid
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
.
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 is QPSK 1 4 0.5 (lowest available).
