It also enhances telnet by replacing simple password access with a shared-key system, where you have to present a great long encryption key to login. This stops people trying to get in by simply trying lots of different passwords, since the key is too long and difficult to guess in a reasonable period of time. Additionally, unlike a simple password the key is never sent over the network so bad guys can't sniff it off the wire.

We use SSH all the time at ntl, so I'd be very surprised if it was blocked, half our techs have cable modems and use SSH for work or their own servers.
