The Barrett 2060 is a fully automatic telephone interconnect, which enables high frequency radio network stations to become part of the international telephone network. HF stations can direct dial any telephone number on the international telephone network. Additionally stations can call up to 98 programmable pre-set telephone numbers stored in the 2060 telephone interconnect. Telephone subscribers on the international telephone network can dial into the 2060 interconnect and call any station on the HF network.
The Barrett 2060 interconnect also supports MIL-STD 188-141B ALE allowing ALE networks to have fully automatic access to the telephone network. The Barrett 2060 interconnect provides full network management facilities including variable access levels for HF stations calling the telephone network, comprehensive call logging for charging purposes and remote supervision by a dial up computer link.
Recordable voice messages allows system greetings and instructions to be in any language, stored in non-volatile Flash RAM.
Should the selectable standard international telephone call progress tones not operate in certain countries, the 2060 can record, learn and store these non-standard call progress tones on site.
When not handling traffic, if enabled, periodic beacons are sent on all channels at regular intervals. This allows the HF users to evaluate the best channel to use with the 2060 base station.
Using a PC loaded with Barrett 2060 remote software, parameters, access levels and call logging information can be downloaded via the telephone network.
This allows the 2060’s to be installed at remote locations and be controlled from a central point.
ALE simplifies the operation of the system as the HF network user need only enter the 2060 address and a telephone number required and the telephone caller has only to enter the mobile number required. The ALE system establishes the link between the two.
Call charging information is stored in the 2060 and can either be based on call duration or information provided by 12 to 16 kHz or 50 Hz metering pulses.
(Note:- The Telco providing the line connected to the 2060 must be requested to provide these metering pulses).
To allow operation of the 2060 on older exchanges Decadic dialling as well as DTMF can be selected.
Stations within the HF network can be allocated individual access levels in relation to the telephone network, i.e. local calls only, full ISD call access, specific number barring or complete barring.
A DSP (digital signal processor) noise reduction system provides clearer reception from the HF network can be toggled on or off by the telephone caller.
Should telephone connection be of such poor quality that the automatic VOX becomes unstable, the telephone caller can switch to manual VOX on their telephone to change the 2060 from transmit to receive.
The telephone caller can request the frequency of the currently selected channel in kHz on their telephone keypad.
The keypad can also by used to will provide the software version, PA temperature, supply voltage during transmit and the percentage of billing storage used from the 2060 and its associated 2050.
While scanning, all types of emergency calls received will be annunciated both audibly and visually on the associated 2050 transceiver (if a front panel is fitted).
98 pre-programmed telephone numbers stored in the 2060 can be accessed by HF manpacks, vehicles or base stations that only have Selcall and not the full dial Telcall option fitted.
