DUNS ERROR 737
737 - Loopback
Error 737 is triggered by a loopback of data
involved in setting up a PPP connection after the modem successfully CONNECTs to
the remote modem.
This error may occur when making calls to ISPs
that use an authentication protocol within PPP (point-to-point protocol).
ISPs using authentication after PPP - may
include/require a dial-up script or other proprietary dialer. In some cases, a
plain-text string is transmitted to the RAS, and then a PPP session is
established. If the PPP session isn't established because the local system is
receiving back the packets it is sending, error 737 may be reported.
The problem may be timing: a script that has DELAY
# (where # is a number representing seconds) may need a value 1 or more
seconds greater; or, if there is no delay, one may be needed.
Examine the PPP Log to see
details of the PPP setup failure.
