I think he means standard telnet not TN3270.

But TN3270 clear text connections are basically the same as telnet or any other TCPIP client/server - other than some negotiation and actions specific to the TN3270/TN3270E protocols.

TN3270 encrypted sessions, on the other hand, start out with the same logic used to connect to an https:// web site. Once established, both sides run the same internal logic as a clear text session.

We use ssh on all systems. No telnet.

How does TN3270 connect?  I had thought it was TELNET with some
handshaking.  Or used to be.  Headshaking?
