All statistics are read-only. Select LanToWan to view the Tx compression statistics of the
modulator’s transmission path:

Description
Top Line
Bytes In
The total number of bytes, displayed in scientific notation, sent to the compressor.
Savings
The XX% (percentage) value is calculated using the following formula:
100 * (1 - (Bytes Out/Bytes In))
Bottom
Line
Bytes Out
The total number of bytes, displayed in scientific notation, including compression and
encapsulation overhead, to be sent over the satellite. Bytes Out is the same as Bytes
to WAN (see Section 6.2.3.6.1 (Monitor: Stats) IP).
Last 10s
Calculated using the exact same formula as Savings (XX%), but uses the Bytes In and
Bytes Out for the past 10 seconds so you can see what compression is being
accomplished on current data.
Select WanToLan to view the Rx decompression statistics of the demodulator reception path.

Parameter
Description
Top Line
Bytes In
The total number of bytes, displayed in scientific notation, including compression and
encapsulation overhead, sent to the decompressor.
Savings
The XX% (percentage) value is calculated using the following formula:
100 * (1 - (Bytes Out/Bytes In))
Bottom
Line
Bytes Out
The total number of bytes, displayed in scientific notation, output from the
decompressor. This represents all the traffic received by the modem.
Last 10s
Calculated using the exact same formula as Savings (XX%), but uses the Bytes In and
Bytes Out for the past 10 seconds so you can see what compression is being
accomplished on current data.

(Monitor: Stats) Compression  Clr (Clear Statistics Buffer)
Use the  arrow keys to select Y (Yes) to clear the Compression statistics buffer. The default
is N (No). Press ENTER to clear the buffer, or press CLEAR to back out of the command and
return to the previous menu.
6.2.3.7 (Monitor:) Buffer
WAN Buffer Fill Status: 100%
This read-only screen indicates the fill state of the Modem to WAN or Modem to Satellite Buffer.
When the WAN Buffer Fill Status figure is increasing, this indicates that user traffic is exceeding
the capacity of the satellite link. If the figure is decreasing, this indicates that there is more
satellite capacity than there is user traffic.
