This is from the install at my Inlaws place in Papakura.
The Antenna Install - 900mHz pointing at the cell tower (Top Antenna).

The Router / FXS Unit itself.

The Connectors on the Unit
Left is a USB "B" 5v 2A power, then an SMA Antenna connector, 4 Ethernet and an FXS.

The Underside of the Unit.
The sim slot is on the right (Our sim is blank white)

And the Web interface, default user/pass is admin
Interestingly, look at the IP address, the public IP was 124.x.x.x

The installer said that the signal wasn't good enough for us to use the FXS port.
We have a few trees between us and the Cell Tower.
