You will need to modify the PAM configuration. By default, PAM is setup to restrict root login to only terminals listed in /etc/securetty. You will either need to modify this file, or to allow root to login from anywhere you will need to remove the line:
auth required pam_securetty.so
from:
/etc/pam.d/login

.... Also, don't forget that telnet transmits unencrypted passwords accross the network. That is why pam is configured this way by default. You should try to use ssh if you can. SSH should have been loaded by default.

Hi,

By default, in order to reduce intrusion damage, root user may not connect to a computer via network directly, only via console or with su from a logged in user.
In order to change the degaul, look at files in /etc/security. One of them, console.perms should permit to root telnet access.

HTH
BTW, why do you use FEDORA ? AS2.1 is much better

Do not make root login by modifying the default pam settings. It is meant to remain like that! You can use ssh or telnet-ssl to login an user, after which that user can acquire root privileges via su. Take care ....
