4.6.3 Protocols Supported
TCP/UDP/IP - Transport Control Protocol/User Datagram Protocol/Internet
Protocol, providing connectivity over LAN/WAN to any
networked computer.
HTTP - HyperText Transport Protocol, providing a Web-browser interface
to the management computer. (‘Max. number of simultaneous
connections’ = unlimited, although only one is processed at a time)
HTTPS - Hypertext Transfer Protocol over Secure Socket Layer is a Web
protocol that encrypts and decrypts user page requests as well as
the pages that are returned by the Web server. It uses Secure
Socket Layer (SSL) as a sublayer under its regular HTTP
application layering. HTTPS uses port 443 instead of HTTP port
80 in its interactions with the lower layer, TCP/IP. SSL uses a 40-
bit key size for the RC4 stream encryption algorithm, which is
considered an adequate degree of encryption for commercial
exchange.
FTP - File Transfer Protocol, providing access to the ‘FTP file system’
of the TANDBERG Gateway. (‘Max. number of simultaneous
connections’ = 1)
TELNET - Provide a standard command-line interface to management
functions. (‘Max. number of simultaneous connections’ = 8)

telnet connection where the password is not sent over the network,
hence impossible to sniff.
