Physical resource placement
As a default, resources should be balanced as uniformly as possible. For example, if 11 Media
Processors are required in a Network Region that has three PNs, two of the PNs should house
four Media Processors each, and the other PN should house the final three Media Processors.
This applies to signaling components C-LANs and IPSIs, also. The MGs usually generate much
more signaling traffic than IP endpoints, even though they each take up one only socket on the
C-LAN and one DLCI on the IPSI. Therefore it is advisable to practice even distribution for both
MGs and IP endpoints among available C-LANs, IPSIs, and the port networks they reside in.
Advanced users should be able to manually override the resource-placement defaults. For
example, there might be reasons beyond traffic engineering for specifying an unbalanced
system or an over-engineered resource pool, such as reliability, cost, security, physical
constraints, and so on.

Final checks and adjustments
The final step in the design process is to verify that the final configuration proposal meets the
following criteria:
