  • Page 7: Introduction

    Introduction The 960 HF Telephone interconnect is designed to provide users on a HF network full interconnection with the international telephone network. It is designed to be operated as a completely automatic facility with no requirement for human operator supervision. A high level of security is incorporated to eliminate system abuse.

  • Page 8: Facilities Available To The Telephone User

    Facilities available to the telephone user A telephone subscriber using a DTMF telephone can access the following facilities provided by the 960 telephone interconnect. These facilities are available after the 960 has answered the call and played its recorded instruction messages.

  • Page 9: Sending A Telcall

    Using the Voice Operated Switch (VOX) The transceiver being operated by the Barrett 960 telephone interconnect is usually switched between transmit and receive using the telephone subscribers voice to derive the switching signal. This is achieved using a specialised VOX (voice operated switch).

  • Page 10: Completing A Call - "Hanging Up

    Note: ID's 9900 and above are reserved for ALE calls. Facilities available to the HF station For more detailed information on how to call the interconnect using Barrett 530,550,930 and 950 transceivers refer to the relevant transceiver operation manuals. Sending a beacon Request To receive a beacon revertive from the 960 interconnect, send a Selcall to the ID xx99, where xx is the self ID of the interconnect.

  • Page 11: Sending An Ale Call

    Sending an ALE call ALE calls may be sent to Interconnects fitted with the ALE option. The transceiver must also be fitted with an ALE board. Preset numbers are allocated by the Interconnect operator. Preset numbers are allocated according to which destination address is used.

  • Page 12: Completing The Call - "Hanging Up

    The 960 operator can select 'Place Off Line' from the manual operator's control menu. Once a telephone call is complete, the Barrett 960 will revert to scan if scanning is selected as the system default. Sending a Selcall to a HF station Enter manual mode by pressing '0'.
