Abstract
A communications network router is described for secure routing of calls between domains of different classification levels. The network router includes a first communications port arranged to receive a first communications channel of a first domain, a second communications port arranged to receive a second communications channel of a second domain, a switch apparatus arranged selectively to connect the first port to the second port to establish a communications link between the first and second domains. The first domain has a different level of classification to the second domain.
Claims14
A communications network router comprising:
- a first communications port configured to receive a first communications channel of a first domain;
- a second communications port configured to receive a second communications channel of a second domain;
- a switch apparatus configured to selectively connect said first port to said second port to establish a communications link between said first and second domains, wherein said first domain has a different level of classification relative to said second domain;
- and
- a manual switch operable to control selective connection of said first port to said second port, manual operation of said manual switch by an operator being required for each instance of said selective connection of said first port to said second port.
A method of establishing communication between a first domain and a second domain, the method comprising:
- (i) receiving by a communications network router of a first communications channel of a first domain at a first communications port;
- (ii) receiving by the communications network router of a second communications channel of a second domain at a second communications port;
- and
- (iii) an operator manually initiating a connection process to selectively connect said first port to said second port to establish a communications link between said first and second domains, wherein said first domain has a different level of classification to a said second domain.
