This HF data system provides email, fax connection services .. between remote stations located up to 2500km apart, using HF waves as the transmission medium. This system is very easy to install and operate.
The system is transparent to the direct user through the support of popular software such as MS Outlook, Lotus Note as well as other popular software.
For the system administrator, the system supports multiple automatic connection options and a link scheduler fully compatible with MIL-STD 188 141B ALE and CCIR call selection protocol is provided to achieve HF email network solution.
