STATUS Menu Item Definitions
The STATUS Menu displays information about the hardware configuration of the link and the performance
of the modem unit and the link. The items in this menu do not accept user input.
Table 3-3. Status Menu Items
RF Signal Level
The relative strength (arbitrary normalization) of the power
received by the RF unit from the antenna. Typical values are
from 83% to 100%.
Signal Level
The relative strength (arbitrary normalization) of the power
received at the baseband processor. This is a measure of
whether the signal received by the antenna is from the other
end of the link or from a noise source. Typical values are 40%
to 70%.
Pre-FEC BER
This is the rate of bit errors that are received from the link,
before correction by the Forward Error Correction (FEC)
circuitry. In usual operation, the FEC circuitry corrects most of
the bit errors so that the error rate of the data sent to the
user’s equipment is smaller than this rate. See Advanced
Menu section for details.
Data Rate
This will read either E1 or T1, depending on how the modem
was configured at the factory.
Software Version
Firmware Version
Displays the version numbers of the software and firmware
that are installed in the modem unit.
Serial Number
Displays the serial number of the modem unit.
Channel Plan
Note: A “B” channel plan is also
available which operates at a slightly
different frequency.
The RF channel plan for the link. The possible options are
A1..A2 and A2..A1, where the first value is that of the local RF
unit and the second that of the far-end RF unit. This setting
has no operational effect on your link.
