Technical Description of TANDBERG Gateway with software version G2

operating systems), which includes the necessary programs such as:

•An FTP client (please see ‘Upgrading software in TANDBERG Videoconferencing units’- document D10238 - for details)

•A web-browser (please see ‘TANDBERG Gateway User Manual’- document D13187 - for details)

•A Telnet client (please see ‘TANDBERG Gateway API’- document D13202 - for details)

•A terminal emulator for the RS232 port (please see ‘TANDBERG Gateway API’ - document D13202 - for details)

4.6.3Protocols 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 CHALLENGE - An option to the standard Telnet service. Telnet Challenge offers a

 

telnet connection where the password is not sent over the network,

 

hence impossible to sniff.

SNMP9 -

Simple Network Management Protocol, standard for network

 

management and surveillance. (RFC1157 SNMPv1, RFC 1213

 

MIB-II).

DHCP -

Dynamic Host Configuration Protocol, enabling the system to

 

automatically be given IP address and Subnet Mask when

 

connected to a network with a DHCP server.

In addition to the above, TCP/IP based protocols allowing management to be performed
