OK - that's interesting.
I set a Telstra/Thomson device up for a neighbour (two doors away) a few weeks ago, probably one like yours, but we left the wireless implementation for a future date.
I was surprised how little information was offered (or indeed required) with the package. It's all on the CD. I think there is a manual of sorts on the Telstra setup CD, and I took a copy, but it's very much lacking in technical stuff of any kind.
I'll have a closer look at the device at this end later tomorrow and see what I can 'discover'.
More later - unless someone else sees an answer at this stage
.
