Others have explained why, but I think your question was really, "how?"
If RH is anything like ancient Slackware in this regard, look for
/etc/securetty. root can only login on the terminals named there. If
you really want to allow people to attempt root logins via Telnet, add
the /dev/ttyp* special files to the list in that file. But you'd be
better off to leave things alone and make people use su so you can track
them, as others have suggested.
