3.2 BIT SWITCHES
WARNING
Do not adjust a bit switch or use a setting that is described as “Not used”,
as this may cause the machine to malfunction or to operate in a manner
that is not accepted by local regulations. Such bits are for use only in other
areas, such as Japan.
NOTE: Default settings for bit switches are not listed in this manual. Refer to the
System Parameter List printed by the machine.

are listed on the Journal for each G3
communication.

e.g. 0000 32V34 288/264 L0100 03 04
(1) (2)(3) (4) (5) (6) (7) (8)
(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 (refer to the note after this table 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.
Note:
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: 0000 32 V34 288/264 L 01
00 03 04
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
