I have a Thinwire Ethernet wiring question.  I know that each segment has a
maximum length of 185 meters and 30 devices.  The question is the definition of
'device'.  We wire an office group by chaining a segment thus:

>-------------+  +------------->
Ethernet in   |  |  Ethernet out
              |  |
           +--------+
           |  |  |  |  Wall box
           |  |  |  |
           +--B--B--+  B = BNC connector crimped inside box
              A  A     A = BNC twist-on
              |  |
              |  |     (2) 10 foot cables
           +--+  +--+
           |        |
           +--ATA---+  T = BNC T-connector

We always thought this counted as one 'device'.  We just learned that each BNC
connection should be counted as one 'device'.  Is this true?

Is the above 1, 3 or 5 devices?

Thanks for any info,
-Bruce
