System Switch 00 (SP No. 1-101-001)
No Function Comments
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.
ƒ
EQM and rx level are fixed at "FFFF" in tx mode.
ƒ
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.

G3/G4 communication
parameter display
0: Disabled
This is a fault-finding aid. The LCD shows the key
parameters (see below). This is normally disabled
because it cancels the CSI display for the user.
