The benefits of HF radio do not end with simple voice telephony. Barrett 923 fax and data systems and 960 telephone interconnect have also been designed to allow the non-technical user to install and operate the system. CC Mail and MS Mail are compatible with the system giving a familiar screen to the users of these packages. Fax is enabled from an on-screen word processor. Alternatively, images may be scanned and relayed over the network.
All mailboxes are password protected.
Only a supervisor can change system configuration. The over-air data is encrypted. Only those registered on the system can receive mail from the system, those outside will be unable to get in. Even other 923 users, unless registered, will not be able to enter the net. The 923 can be configured to be fully automatic and, when used with the 960 telephone interface, will collect messages from the Internet and distribute to the required mailbox.
