Re: [foxboro] Reliability of Copper Carrier Band Lan interfaces

All I can say is we've had to replace two over a 14 year period.  We'll
be moving to a mesh network over the next few years.

Dear List, 

I am trying to ascertain a spares strategy for the next couple of years
to
support the lifecycle support agreement and wondered if anybody had
data on
the above question.

For us a critical question is how often these devices fail verses how
many
we have installed. This will allow us to take decisions on when to
upgrade
certain parts of our network.

For us here, we have 10 devices, and we have a failure of 1 every two
years,
giving me 0.5 failure per year figure. 

Does anybody else have similar information that I could use to confirm
my
figures ?? 

Also, on a broader note, are these figures available anywhere else for
this
device, and any other Foxboro Devices ? 

Thank you,
