[USR-TC] need help setting up a "telnet" user that telnets to a host

I'm trying to duplicate the functionality we have in our ascends, namely this user... unixuser Service-Type=Login-User, Login-Service=Telnet, Login-TCP-Port=23, Login-IP-Host=192.168.100.101 (This isn't merit radius, no need to comment that the syntax is wrong) is telneted directly to the ip host listed when he logs in. On the hiperarc, the call is just dropped. Any ideas? thx,
