Corey,

We use ZCP's because we were told only the ZCP could handle both FBM100 and
FBM200 on the same CP. The FCP was cheaper but we would need more of them
because we had to split our FBM100 and FBM200 on seperate CP's. This also
means we would have a lot of P2P links (blocks which were in the same CP
talking to each other would now be in different CP's) Also we wanted to
keep our CP's in the control room, reusing the old IE32 cabinets. Besides
,the ZCP has more capacity.

For a completely new setup we would consider using FCP's ie we will have to
replace our old HIU - TP's setup sometime next year or so (as soon as
budget allows) and will probably use FCP for that.

"As a rule of thumb, I recommend FCPs over ZCPs in almost all cases."

Interesting comment.  We are evaluating migration options here, and so far
have been assuming ZCP270s.  Aside from being able to use existing racks
(which varies in importance from installation to installation, and may be
superseded by other factors), the ZCP has a 100Mbps fieldbus.  That's
overkill for sure, but I was worried that the 2Mbps fieldbus of the FCP
might not be enough for the full 60-FBM complement, especially if using
many FDSI or DCI FBMs.  The FCP advantages were simplified cabling and
less installation space (since it mounts in an FBM baseplate or something
similar).


But your statement below, that the ZCP lacks some software functionality
that the FCP has, is news to me.  Are there plans to add it to the ZCP
image?  Is FCP going to be the future direction (and in the process, will
ZCPs get end-of-life'd faster)?  Are you going to have to keep them more
environment-controlled than the FBMs (we have already seen by accident
that the FBMs will not meet their stated ~140°F temperature ratings)?


Also, what is TDR/TDA?  Those are TLAs I haven't heard yet.
