APPENDIXE
ISDN BRI Cause Values
This appendix describes ISDN BRI standard cause values that might be received 
from the ISDN switch when using Cisco 800 series routers. These values are sent 
from the ISDN switch to the router to indicate ISDN call status.
Although telephone service providers generally define cause messages with 
decimal values, Cisco 800 series routers display the hexadecimal (or hex) 
translation of the decimal value.
Cause...
