One of the following factors
could be the cause of this error:
• In the User Tools, check the
settings for the dial-up user
name and dial up password.
• Modem has been
disconnected.
• Modem board disconnected.
Check the following for a machine that is
using Cumin (NRS modem):
• An error was returned during the dialup
connection
• A network was detected at startup
• At startup the machine detected that the
NIB was disabled, or did not detect a
modem board

Error Problem Solution
1 Failure to certify dial-up
In the User Tools, check the dial-up user and dial-
up password settings
4 Illegal modem setting
Check the setting of SP5816 160 to determine
whether the setting for the AT command is correct.
If this SP setting is correct, then the problem is a
bug in the software.
5
Poor connection due to low power
supply on the line.
The problem is on the external power supply line, so
there is no corrective action on the machine.
11
Data in the NVRAM became
corrupted when the network enable
switch and Cumin-M were enabled
at the same time.
Use SP5985 1 and set the NIC to "0" (Disable) to

The modem board could not enable
the NIB.
Replace the modem board.
