I am not sure when the idea of using "circuit name" got into this discussion
but I am panicking about the consequences. I am not sure also of the 
motivation. Whatever could be done with "circuit name", it could be done
with "phivCircuitIndex".

And, it could be done with so much less complication and less memory!

I have to deal with not only a management station but also with the
routing implementation. 

So, please use "phivCircuitIndex" with whatever name you prefer.
