Once the Telnet connection is established, it is necessary to initiate
a TL1 session. Establishing a TL1 session involves successful user
authentication. Until a TL1 session is established, all commands
other than those used to initiate or terminate a session will be
denied (autonomous messaging is also disabled). Authentication
involves the successful entry of a
username/password

session, see the section
TL1 Commands
on page 9-5.
