Shared Resources or Not

All,
Have a CM6.2 Core location with 10 PN's connected. Duplicated IPSI's in all 10. I have a few Tn744's C's and higher in a couple of the PN's. Lets just a PN 6 (1) and PN 7 (2). When doing the command "li measurements tone detail today" I get an output of the 10 PN's with the DTMF PN reg and PN alloc numbers. The PN 6 and PN 7 numbers are off the chart when compared to the other port networks. PN 7 is around 3700+ requests, about the same as all the other PN's put together.
In a fiber connected CM system I would think this is normal. In a IP based system this doen't make much sense.
Does an IP based system share these resources? I thought they were PN specific when it came to call-classifier ports.
thanks,

resources are shared across the system. If you don't like this, remove your tn748 tone detector and tn744 classifier boards. You should have plenty of on PN resources with tn2182 and tn2312 boards.

Which resource is choosen by applications first, the IPSI or the TN744/748?
 
The search algorithm the switch uses is to search for a given
type of tone detector (i.e. DTMF, CC-TTR, ...) from the top of the
list down; For each entry on the list it will search on the same PN
and then will search off-PN before advancing to the next entry

This means when looking for a CC-CPTR, it will search
in the following order:

1) CLAS-PT (i.e. TN744, TN744B) on the same PN
2) CLAS-PT on any PN
3) ETR-PT (i.e. TN744C) on the same PN
4) ETR-PT on any PN

This algorithim uses the least flexible ports first, and saves the
most flexible for last. This way the TN744C can serve as overflow
for either a CLAS-PT request or an GPTD request, and provides the
optimum utilization of the customers tone detector resources. The
cost of the off-PN allocation is very low, since the holding time
optimum utilization of the customers tone detector resources. The
cost of the off-PN allocation is very low, since the holding time
is short and the fact that there are many more timeslots between
port networks than there are tone detectors.

Thanks that makes sense. But using the resources across an IP based system....doesn't that use up X-fires and bandwidth?
