Table 774 DCC Fault Messages

Message	Fault
DCC: Receive CALL_DISC_IND	The debugging information is probably output
	because:
	The physical connection between the local and
	remote ends is down, phone cable is not securely
	connected to the router, or the quality of phone
	line is not good.
	PPP authentication is not correctly configured, so
	the PPP authentication is failed.
	Remote DCC authentication is failed, because
	name in the commands dialer user and dialer
	route configured for DCC is inconsistent with
	name configured for PPP authentication, and the
	dialer route at the remote end does not contain
	the local network address.
	The remote end disconnects the connection
	because the remote DCC idle-timeout timer has
	timed out.
	Solution:
	If PPP configuration is incorrect or name
	configurations are inconsistent, implement the
	configuration as shown in the above example.
	If it is the problem of the network address, apply
	the following measures in the configuration of the
	remote end: Add the dialer route corresponding to
	the network address of the local router on the
	remote router. Alternatively, remove all the dialer
	routes configured at the remote end, and use the
	dial number.
DCC: link negotiation Down on	The link is probably disconnected because PPP
interface ***	negotiation is failed due to a wrong PPP
	configuration. To solve the problem, refer to the
	previous example to make the configuration.
DCC: NAME authentication ERROR,	The debugging information is probably outputted
failed	because name configured in the commands dialer
	user and dialer route is inconsistent with that
	configured in PPP authentication. The connection is
	disconnected since the local DCC authentication
	has been failed. To solve the problem, refer to the
	previous example to make the configuration.
