In pseudo code it would be something like:
if (length(ADSL-Agent-Remote-Id) > 31) {
update reply {
    strncat(SubscriberID, ADSL-Agent-Remote-Id +
(strlen(ADSL-Agent-Remote-Id) - 31), 31)
}
}
else {
update reply {
    SubscriberID := ADSL-Agent-Remote-Id
}
}
Where in effect if the string is longer than 31 chars take the right
most 31 chars and only return that.
if ( ADSL-Agent-Remote-Id =~ /(.{0,31})$/ ) {
   update reply {
      SubscriberID := "%{1}"
   }
}

that should do it.
