Overview
BC205000
ALE – Automatic Link Establishment
An embedded internal option fully interoperable with FED STD 1045
ALE systems. Also capable of full 16 digit telephone dialling (using FED
STD 1045 ALE as the signalling medium) with Barrett 960 or Barrett
2060 ALE equipped telephone interconnects.
Selective Call options
Fitted with both a CCIR 493-4 based, four and six digit system of which
the protocol is available for free distribution and an OEM protocol that is
fully compatible with other major HF manufacturers’ four and six digit
systems that utilise encryption.
BITE – Built-in Test Equipment
Tests receiver performance, Selcall, syllabic mute, VCO operation and
serial communications port viability.
Programming by IR or serial port
For ease of programming in a vehicle a notebook computer loaded with the 2000 series programming package can load a transceiver’s parameters without the need for cables through the remote head IR port.
Second antenna connector
Allows each channel to select one of two antennas – ideal when long and short distance antennas are used.
Digital Signal Processing (DSP)
A single DSP chip provides modulation and demodulation of all on air signalling used in the ALE, Selective Call and syllabic mute processes and provides noise reduction of received signals.
Frequency hopping option
A simple to operate, unique frequency hopping system that has no network entry time or late entry time. Simply enter the hop band, cipher key number and talk.
Simple architecture
The transceiver uses only two microprocessors, the main processor uses a soft loaded core while the second processor is used within the control head to operate the display and keypad.
Size and weight
The 2050 in a local control configuration measures only 185(w) x 270(d) x 70(h) and weighs less than 2.6 kg. Housed in a lightweight, extremely strong sealed aluminium chassis, 2050 meets MIL-STD 810G for drop,
dust, temperature, shock and vibration.
GPS tracking
An option that supports connection to an external GPS receiver for tracking applications using the Barrett 977 tracking system.
Direct dial telephone calls
“Telcall” option provides direct dialling access with Barrett Communications’ HF Telephone Interconnects and most interconnects from other manufacturers.
“SMS Pagecall”
Allows short text messages to be sent from one 2050 transceiver to another. Barrett 2050 transceivers have alpha-numeric input keys(similar to mobile phones) that allow direct text message input (without the need for an external PC or Palm type input device).
HF email fax and data
The 2050 transceiver auxiliary connector is fully featured to interface to a variety of external modems including the Barrett 2020 HF email system.
The Barrett 2020 Email fax & data system is ideal for the provision of full telecommunication facilities within organizations with remote-sited operations with no existing communication infrastructure.
The 2020 provides a simple automatic interface for speech, data, fax and email among all stations in the HF Network with full connectivity to internet, email and fax facilities via the international telephone network.
Configuration Flexibility
The 2050 transceiver is packaged as a desktop(local control) transceiver and with the addition of the simple and inexpensive mobile pack the 2050 is quickly reconfigured to a mobile (trunk mount) transceiver. This feature simplifies the logistics of stocking the right transceiver for the right application. The modular design of the 2000 series of products, as a whole, enables a basic 2050 transceiver to adapt quickly and easily between base station, mobile, and email fax & data configurations.
