This MIB module defines the objects that support provisioning
of 'container' class physical entities.  Provisioning sets up
a 'container' to hold a specified physical entity.  This allows
a management client to configure the specified physical entity,
including all of its subordinates physical entities, before
installation.

Consider a network manager of a CLEC (Competitive Local Exchange
Carrier) planning for the installation of the hardware necessary
to support several new subscribers.  This network manager wants
to pre-configure the ADSL (Asymmetric Digital Subscriber Loop)
modems that will support these subscribers, thereby reducing the
bring-up time once they arrive.  Under normal circumstances this
would not be possible.  However, provisioning allows the network
manager to 'create' the physical entities that represent the new
modems.  In essence, the device simulates the installation of
the new modules into the system.  This has the effect of creating
all conceptual rows in all the necessary tables that support the
physical entity and all its subordinate physical entities (e.g.,
entPhysicalTable, entAliasMappingTable, and ifTable).
