Figure 1 BCM50 network management model
“BCM50 enterprise network model” on page 28 shows an example BCM50 enterprise network,
illustrating the various communications between the BCM50 end devices and management
applications managing end devices. The diagram also shows that the physical enterprise network,
conceptually, is segmented into domains.
The Network Operations Center (NOC) domain represents the tools, equipment and activities used
to analyze and maintain the operation of a network of BCM50 devices. Element Manager and
Network Configuration Manager are the management applications which allow the network
administrators working in the NOC domain to perform the administrative functions. The
management application workstations can be physically distributed across different enterprise sites
if they are networked via an IP network as represented by the cloud in the middle of the figure.
The BCM network domain represents one or more BCM50s located a different sites in the network
connected through an enterprise LAN to one or more management application workstations. The
WAN represents an adjacent network, external to the LAN.
The VoIP and Wireless VoIP domains represent terminating IP devices.
