debug atm events Command

Use the debug atm events command to display events that occur on the ATM interface processor and to diagnose problems in an ATM network. This command provides an overall picture of the stability of the network. The no form of this command disables debugging output.

If the interface is successfully communicating with the Digital Subscriber Line Access Multiplexer (DSLAM) at the telephone company, the modem state is 0x10. If the interface is not communicating with the DSLAM, the modem state is 0x8. Example 14-5shows an ADSL line that is up and communicating successfully. Example 14-6shows an ADSL line that is not communicating correctly. Note that the modem state does not transition to 0x10.
