Meaning
Max Receive
Modulation Mode
The maximum mode the unit will use as its adaptive modulation. By
default the Max Receive Modulation Mode is the highest mode available.
For minimum error rates, set the maximum modulation mode to the
minimum necessary to carry the required traffic.
Lowest Ethernet
Modulation Mode
The lowest modulation mode that must be achieved before the link is
allowed to bridge Ethernet frames.
Link Mode
Optimization
IP Traffic: The link is optimized for IP traffic to provide the maximum
possible link capacity.
TDM Traffic: The link is optimized for TDM traffic to provide the lowest
possible latency.
Regulatory Band
The regulatory band selected from the list in the license key.
Channel Bandwidth
Bandwidth of the transmit and receive radio channels.
Link Symmetry
Only displayed when Master Slave Mode is set to Master.
Adaptive: Allows link symmetry to vary dynamically in response to
offered traffic load. This is not supported in the following cases:
•
Where radar avoidance is mandated in the region.
•
Link Mode Optimization is set to TDM Traffic.
“2 to 1”, “1 to 1” or “1 to 2”: There is a fixed division between transmit
and receive time in the TDD frame of the master ODU. The first number in
the ratio represents the time allowed for the transmit direction and the
second number represents the time allowed for the receive direction. The
appropriate matching Link Symmetry is set at the slave ODU
automatically. For example, if Link Symmetry is set to “2 to 1” at the
master ODU, then the slave ODU will be set automatically as “1 to 2”. In
this example, the master-slave direction has double the capacity of the
slave-master direction.
Spectrum
Management
Control
In regions that do not mandate DFS (radar detection), the options are:
DSO
Fixed Frequency
In regions that mandate DFS (radar detection), the options are:
DFS
DFS with DSO
This attribute is disabled if the regulatory requirement is fixed frequency
only.
