Introduction Prerequisites Requirements Components Used Conventions Cause Code Origination Point Disconnect Cause Code Optional Diagnostic field Related Information Introduction This document cause code 0 explains how to interpret Integrated Services Digital Network (ISDN) disconnect cause codes. The ISDN disconnect cause code appears in the debug isdn q931 command output, and indicates the reason for call disconnection. Note:Activate the http://www.cnes.com/causecodes.html debug isdn q931 command for this exercise. Remember that the debug isdn q931 command generates a large volume of debugs. Refer to Important Information on Debug Commands for more information on the safe use of debugs. Here is a sample output of the debug isdn q931 command. The output indicates the disconnect cause code for a failed ISDN call: Calling#ping 10.10.10.2 Type escape sequence to abort.
