Benefits to BGAN users
Tieline BGAN connections offer a number of benefits to broadcasters including:
•
The ability to connect reliably and affordably, and broadcast live FM quality audio from
remote locations.
•
The flexibility to connect using either IP or ISDN connections, depending on the broadcast
situation and available connection bandwidth.
•
The ability to send high quality audio from a remote broadcast site and receive audio from
the studio over the same connection.
4 Typical
users
•
Broadcasters performing broadcasts from remote locations and wanting to send and
receive live broadcast quality mono or stereo FM audio between the remote site and
studio.

Setting up Tieline for ISDN broadcasting
This section describes how to set up BGAN for use with Tieline codecs and gives an example of an
ISDN broadcast configuration.
5.1
Equipment needed
•
Tieline codec at the remote broadcast location connected to a BGAN terminal.
•
Tieline codec at the studio connected to an ISDN B channel.
•
PC for programming the BGAN connection and monitoring the codec connection.
•
ISDN grade cable with RJ-45 connectors on both ends.
Tieline recommends connecting between the RJ-45 connector on a BGAN with an ISDN port like
the Hughes 9201 or the Thrane & Thrane EXPLORER 700 terminal and a Tieline ISDN module (for
ISDN connections). You can also use the vehicular terminals, such as the Hughes 9250 and the
Thrane & Thrane EXPLORER 727.
Some terminals, such as the Thrane & Thrane EXPLORER 500, have ISDN via USB, which is NOT
compatible with Tieline codecs.
Important note:
Please ensure that your Inmarsat service supports 64Kbps UDI (Unrestricted
Digital Information). Make sure that the terminal settings are set for 64Kbps UDI operation and that
the SIM is enabled for Data. If the service is RDI, only lower quality voice connections are
supported (i.e. G.711 algorithm).

Setting up the BGAN terminal
WARNING
:
Don’t stand in front of the BGAN terminal when pointing the antenna and do not touch
the front of the antenna module. Hold the support bracket and the transport lock of the antenna
while pointing the antenna. For your safety, always maintain a minimum distance of 1 meter from
the front face of the antenna.
To set up the BGAN terminal:
1. Open the BGAN terminal and position the face of the satellite toward the sky.
