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.
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 overengineered 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:
All endpoints and media gateways have been assigned to various Network Regions, sites,
and/or Communication Manager systems, according to customer specifications.
The placement of resources adheres to the physical capacities of the proposed platform.
The number of PNs and/or Media Gateways is sufficient to handle the TDM traffic, the
required number of IPSI circuit packs, and the required number of port circuit packs.
The number of C-LAN circuit packs is sufficient to support the desired number of IP
endpoints, Media Gateways, and certain adjuncts.
The number of media processing circuit packs is sufficient to handle both calls involving IP
endpoints, and interport network calls between circuit-switched endpoints, unless a
circuit-switched center stage is used instead of IP-Connect.
The anticipated call volume can be handled by the server.
There is sufficient bandwidth in all IP networks to support the anticipated media traffic.
