Example:
(1): EQM value (Line quality data). A larger number means more errors.
(2): Symbol rate (V.34 only)
(3): Final modem type used
(4): Starting data rate (for example, 288 means 28.8 kbps)
(5): Final data rate
(6): Rx revel (see below for how to read the rx level)
(7): Total number of error lines that occurred during non-ECM reception.
(8): Total number of burst error lines that occurred during non-ECM reception.
• EQM and rx level are fixed at "FFFF" in tx mode.
• The seventh and eighth numbers are fixed at "00" for transmission records and ECM
reception records.
Rx level calculation
Example:
The four-digit hexadecimal value (N) after "L" indicates the rx level.
The high byte is given first, followed by the low byte. Divide the decimal value of N by -16 to
get the rx level.
In the above example, the decimal value of N (= 0100 [H]) is 256.
So, the actual rx level is 256/-16 = -16 dB
3 Not used Do not change this setting.

Line error mark print
0: OFF, 1: ON (print)
When "1" is selected, a line error mark is printed on
the printout if a line error occurs during reception. This
shows an error position in ECM off mode.

G3/G4 communication parameter
display
0: Disabled
1: Enabled
This is a fault-finding aid. The LCD shows the key
parameters (see "G3 Communication Parameters"
below this table). This is normally disabled because it
cancels the CSI display for the user.
Be sure to reset this bit to "0" after testing.
