1. On the router, issue terminal monitor and debug atm event commands.
   

   Router#terminal monitor
   Router#debug atm event
   ATM events debugging is on
   
   

2. Physically unplug the ADSL Cable (RJ-11) from the Cisco SOHO77 ADSL interface. Wait for a few seconds. Plug the cable back in to cause the ADSL line to retrain.
   If you have access to the digital subscriber line access multiplexer (DSLAM), make the line retrain by shutting down the specific ADSL Terminating Unit - Central Office (ATU-C) interface where the subscriber terminates the DSL connection.
   Note: If you issue the shut and no shut commands on the router, they do not retrain the ADSL line. Even when you administratively shut down the ATM interface, the Carrier Detect (CD) light and the ATU-C port LED are still on. This means that it is still trained up. Unplug and plug back in the ADSL line to make the interface retrain.
   
3. Watch the debug messages on the screen.
   If the modem state stays at "0x8" and says "Could not establish connection," it means that the Cisco SOHO77 has not heard from the central office (CO) . It does not see an incoming signal.
   

   Router# 
   1d01h: DSL: 1: Modem state = 0x8
   1d01h: DSL: 2: Modem state = 0x8
   1d01h: DSL: 3: Modem state = 0x8
   1d01h: DSL: 4: Modem state = 0x8
   1d01h: DSL: 5: Modem state = 0x8
   1d01h: DSL: Could not establish connection
   <... snipped ...>

   If the modem state changes from "0x8" to "SHOWTIME," it means that the Cisco SOHO77 has successfully trained with the DSLAM.
   

   Router#
   00:24:18: DSL: 2: Modem state = 0x8
   00:24:21: DSL: 3: Modem state = 0x8
   00:24:23: DSL: 4: Modem state = 0x8
   00:24:26: DSL: 5: Modem state = 0x8
   00:24:28: DSL: 6: Modem state = 0x10
   00:24:31: DSL: 7: Modem state = 0x10
   00:24:33: DSL: 8: Modem state = 0x10
   00:24:36: DSL: 9: Modem state = 0x10
   00:24:37: DSL: Received response: 0x24
   00:24:37: DSL: Showtime!
   <... snipped ...>

4. After viewing the debugs, if you do not want to see any more modem state messages, at the router prompt issue the undebug all command. All debugging is turned off.
   

Router#undebug all
