CHAPTER 7 TROUBLESHOOTING
4.5.2 Service Error Code Output
If ‘1’ is set to service data #1 SSSW SW01 bit 0, an appropriate service error code will be
indicated on the following reports if a communication ends in error: communication control
report, reception result report, error transmission report.
When an error occurs, you can generate a system dump list in service mode to check the
code.
4.5.3 Error Codes
The error codes used in the machine are defined as follows:
4.5.3.1 Transmission Level (ATT): No.07 of Service Soft Switch #2 MENU
• Increase the transmission level:
Increase the setting so that it is closer to 0 dBm. (At 0 dBm, the LCD indicates ‘0’.)
• Decrease the transmission level:
Decrease the setting so that it is closer to -15 dBm. (At -15 dBm, the LCD indicates
‘15’.)
4.5.3.2 NL Equalizer: No.05 of Service Soft Switch #2 MENU
• Adjust the NL equalizer:
Select ‘ON’.
4.5.3.3 Transmission Page Timer: SW12 of Service Soft Switch #1 SSSW
• Increase the page timer setting:
To set both transmission and reception to the same time-out length, set SW12 as fol-
lows:
8 min:
bit 7, bit 1, bit 0 = 0, 0, 0
16 min:
bit 7, bit 1, bit 0 = 0, 0, 1
32 min:
bit 7, bit 1, bit 0 = 0, 1, 0
64 min:
bit 7, bit 1, bit 0 = 0, 1, 1
If you want to set transmission and reception to different time-out lengths, or use differ-
ent time-out lengths according to different image modes, you will have to set all bits (from
7 through 0) accordingly.
4.5.3.4 T0 Timer: No.10 of Service Soft Switch #3 NUMERIC param.
• Increase the T0 timer setting:
Increase the setting of No.10.
The T0 timer is used to set the period of time in which a line connection is recognized
for transmission, i.e., in which the machine waits for a significant signal from the other
party after dialing. The line will be disconnected if no significant signal is received during
the period.
