Telnet/SSH
Use the Telnet or SSH protocol to connect to any AirLink device and send AT
commands.
A secure mechanism to connect remote clients is a requirement for many users.
In ACEmanager now, Secure Shell (SSH) is supported which will ensure
confidentiality of the information and make the communication less susceptible to
snooping and man-in-the-middle attacks.
SSH also provides for mutual authentication of the data connection.
