The problem may be intermittent, inform the operator of the remote machine, they should
report the problem to the telephone company.
Perform the following:
• Confirm line is standard PSTN / PBX analogue line
• Line quality too poor for Super G3 or G3 to function correctly. Possible mains interference
on line. Possible DSL line, not properly filtered.
• Ask customer to request Fax capable service from telephone company.
• If mains noise, install a new fax module, PL 20.05 Item 1 . Use line 1.
• Enter dC131 NVM Read / Write. Set the value at the following locations:
– NVM ID 200-085 T30 Maximum resolution Line 1 Rx = 7
– NVM ID 200-086 T30 Maximum resolution Line 2 Rx = 7
This sets the receive resolution capabilities for line 1 and line 2 to 400 x 400 max, this will
shorten the DIS.
• The DIS field is too long to enable successful communication.
Enter dC131 NVM Read / Write. Change NVM ID 200-141 USSTOCKSUPPORTRAX to 0
(disable).
• Disable V34 (Super G3). Enter dC131 NVM Read / Write and reset the value at the follow-
ing locations:

– NVM ID 200-090 T30MaxSpeedL2Rx = 11 (14400)
If the problem still exists try a lower line receive (Rx) speed: 12 = 12000, 13 = 9600, 14 =
7200, 15 = 4800, 16 = 2400
