Requiring Encryption for in.telnetd on Solaris 10

I'd like to require encryption for all telnet connections on my Solaris 10 box. In the past, I've been able to do this using MIT's in.telnetd that they include with their Kerberos distribution. I'd like to use Sun's if possible. Does anyone know the right way to require encryption? Thanks.
