2.4.8. Resource Manager (RM) 
IMPORTANT:
The Resource Manager is released for use in standalone
systems with HFA and IPDA.
In a real, complex IP network the available bandwidth is typically
not uniform in all sectors.
The Resource Manager (RM) can administer and monitor the bandwidth
for up to 800 sectors in a given IP network.
The RM updates a cluster matrix whenever a call is setup or torn down.
The matrix allows determination whether there is a resource shortage
in any of the involved sectors. Based on the configured bandwidth and
the actual bandwidth a call is either allowed to complete or rejected.
The RM calculates real bandwidth, taking compression settings, DMC,
FAX, etc. into account.
For more information on the resource manager please refer to Chapter 16, “Resource Manager Functionality”.
