Diagnostics and Troubleshooting

The following table provides an overview of the sequence of troubleshooting procedures for the DSL card. The following sections address potential problems that may occur in each network segment:

If the Client cannot Ping the Gateway Router and . . .

Then . . .

The Client cannot reach the SN	Refer to Table 6-4,Client-to-ServiceNode
	Segment.

The Client cannot reach the DSLAM	Refer to Table 6-5, Service Node-to-DSLAM
	Segment.

The Client cannot reach the IPC	Refer to Table 6-6,DSLAM-to-IPC Segment.

The Client cannot reach the Gateway	Refer to Table 6-7,IPC-to-Router Segment,
Router	and Table 6-8,Router-to-IPCSegment.

The tables in the following sections, each pertaining to a specific network segment, provide suggestions for resolving network problems.

Client Cannot Ping the Gateway Router

When the client cannot Ping the gateway router, specific fault-isolation procedures begin with the first network segment, client-to-service node (SN).
