Step 2 If you do not get any response, to find where failure is occuring, run the following debug commands:

• debug chat script

• debug PPP negotiation

• show cellular all

• show interface cellular

• show running-config

• show controllers cellular

Step 3 Save the output from all these commands and contact your system administrator.
