How to calculate the rx level listed on the TCR (when bit 2 of system switch 00 is set to 1)
Example: V29 96 L 01 0C 00 00
The four-digit hexadecimal value (N) after L indicates the rx level. Divide the decimal value of
N by -16 to get the rx level.
In this example, the decimal value of 010C(H) is 268.
So, the actual rx level is 268/16 = -16.75 dB.
SERVICE TABLES AND PROCEDURES
COMMENTS
1: Instead of the personal code, the following data are
listed on the TCR for each analog G3 communication.
e.g. V33 14 01 03 00 02
First number: Final modem type used
Second number: Final modem rate (for example, 14
means 14.4 kbps)
Third and fourth numbers: Line quality data. Either a
measure of the error rate or the rx level is printed,
depending on the bit 3 setting below. (An M on the
report indicates that it is error rate, and an L indicates
Rx level.) The left hand figure is the high byte and the
right hand figure is the low byte (see the note below
this table for how to read this value). If it is a measure
of the error rate; a larger number means more errors.
Fifth number (rx mode only): Total number of error
lines that occurred during non-ECM reception.
Sixth number (rx mode only): Total number of burst
error lines that occurred during non-ECM reception.
The fifth and sixth numbers are fixed at 00 for
transmission records and ECM reception records.
This bit determines the data type to be printed on the
TCR (Journal) when technical data printout is enabled
by bit 2 above.
If this bit is 1, a mark will be printed on the left edge of
the page at any place where a line error occurred in
the data. Such errors are caused by a noisy line, for
example.
This is a fault-finding aid. The LCD shows the key
parameters (see the next page). This is normally
disabled because it cancels the CSI display for the
user.
Be sure to reset this bit to 0 after testing.
This is only used for communication troubleshooting. It
shows the content of the transmitted facsimile protocol
signals. Always reset this bit to 0 after finishing testing.
Do not change the settings.
