The Diagnostics page allows you to run a series of diagnostic tests of your system software and
hardware connections.
You can view Diagnostic link in the left navigation bar. Following are the options available under

Once you have your DSL device configured, it is a good idea to make sure you can ping the network. A
ping command sends a message to the host you specify. If the host receives the message, it sends
messages in reply. To use it, you must know the IP address of the host you are trying to communicate with
and enter the IP address in the Host Address field. Click Go! To start the ping command, the ping result will
then be shown in this page.
Fields in this page:
Field Description
Host Address The IP address you want to ping.
In order to isolate the ATM interface problems, you can use ATM OAM loopback cells to verify
connectivity between VP/VC endpoints, as well as segment endpoints within the VP/VC. ATM uses F4 and F5
cell flows as follows:
− F4: used in VPs
− F5: used in VCs
An ATM connection consists of a group of points. This OAM implementation provides management for the
following points:
− Connection endpoint: the end of a VP/VC connection where the ATM cell are terminated
− Segment endpoint: the end of a connection segment
This page allows you to use ATM ping, which generates F5 segment and end-to-end loop-back cells to test
the reach ability of a segment endpoint or a connection endpoint.
