ISDN Interface blocking on authentication failure

I have an 803 ISDN router

the system is configured to perform CHAP authentication on incoming ISDN calls. Are there any commands that will allow me to block the interface for a defined period of time following an incoming CHAP authentication failure (or 3 failures in a row)

thank you

Re: ISDN Interface blocking on authentication failure

I don't think that there are any command which allow you to block or shutdown the interface after x number of failed authentication.
