GTB5 - what is it?

[Seb7]

I've started to come across 'GTB5' within the user agent. What is it?

eg:

User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; FunWebProducts; GTB5; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506)

User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; GTB5; InfoPath.2)

User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; GTB5; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506)

Pure guess here - GTB5 might refer to "Gigabit TestBed 5".

There is a set of testing protocols for various levels of gigabit data speeds named GTB1, GTB2, now going up to GTB7, I believe. The acronym in a browser's user agent string could mean that it complies with testing for that level of data transmission.

It's a content filter.

Add "technologies" to the end of the letters (omitting the numeral) and do a google.
