III. The debugging information displayed when DDR fails to interwork with theopposite end and the solution
This section lists in turn the debugging information when DDR fails to interwork with the
opposite end and explains how it is generated. Users may clear the fault by following
the attached solutions.
DDR: Receive CALL_DISC_IND
This debugging information may be generated by the following causes:
a. The physical connection between local end and remote end is cut off, poor
connection between telephone line and router, and poor telephone line quality.b.
Incorrect PPP authentication configuration, PPP authentication fails to pass.
c. The remote DDR authentication fails to pass, the name (dialer remote-name, name
in dialer map) configured by DDR is inconsistent with the name configured in PPP
authentication configuration, there is no local network layer addres s in the remote
dialer map.
d. It is not a fault, while the problem is caused when the remote DDR idle-timeout tim er
is timeout, the opposite end hooks on this connection.
The solutions are as follows:
a. For incorrect PPP configuration, please configure according to the ex ample above.
b. If the names are configured inconsistently, please configure according to the
example above.
c. For the problem of “Network layer address”, please take one of the f ollowing
solutions in the configuration of the opposite end:
