    Hello
    I need to set up an ISDN call from cisco router but from some reason my
    router
    cisco 3725 12.3(9)
    won't take the command:
    "ppp encrypt mppe auto"
    I get this:
    Router(config-if)#ppp encrypt mppe auto
    ^
    % Invalid input detected at '^' marker.


    any idea how to enable this "ppp encrypt" ?
