Page 7-3
 2005, ADC Telecommunications, Inc.
Each Hub/RAN node contains a Bus Scanner process whose responsibility is to discover the
presence/absence of hardware modules and to start/stop HCP’s to manage those hardware
modules. The Bus Scanner MIB reports the information defining the hardware “discovered” at
that node.
Each node contains a Network Node process to manage information about that CPU, where the
interface is the Network Node MIB. This MIB contains information about the CPU itself (e.g.
IP Address, Hostname, etc.), Hub/RAN specific information (Pole ID, RAN Box ID, etc.), and
other miscellaneous status information. In addition, this MIB reports a high-level fault status
for each HCP type. If any HCP in that node reports a fault of any type in its HCP MIB, the
Network Node MIB fault field corresponding to that HCP will report a problem.
2.1 Hub/RAN Connection Relationships:
In Figure 7-1, the solid lines between the Hubmaster and Hub/RAN nodes illustrate Hub/RAN
connection relationships.
The Hubmaster contains a process called the Hub/RAN Config Process that is responsible for
managing the connections between the Hubmaster and the other nodes in the network. This
process uses the Hub Node MIB and RAN Node MIB to manage these connections. The
Hub/RAN Node MIB’s allow specific information about the Hub/RAN nodes to be configured.
This includes such things as Site ID, Pole ID, and RAN hardware connections. The Hub/RAN
Config Process will push the information configured in these MIB’s down to the Network
Node MIB at each node. Refer to Section 3 Network and System Installation and Setup for a
more in-depth explanation of how to use these MIB’s.
The Hub/RAN Config Process is also responsible for preparing the Hubmaster to have tenant
relationships established. This process uses the information set in the Hub Node MIB and BTS
Connection MIB to configure the tenant relationships. Information that is provided in the BTS
Connection MIB as part of Tenant Setup will be pushed down to the Hub RF Connection MIB
in the Hub Nodes. Refer to Section 3 Network and System Installation and Setup for a more in-
depth explanation of how these MIB’s are used.
2.2 Tenant Relationships:
In Figure 7-1, the dotted lines among Hubmaster and Hub/RAN nodes illustrate tenant
relationships.
Once a tenant is created using the BTS Connection of the previous section, then a Tenant
process is kicked off to manage that new tenant. This tenant process uses the Tenant OAM
MIB in the Hubmaster node to allow tenant specific parameters to be configured. These
parameters allow the setting of frequency, gain, and delay values as well as any other tenant
specific information. When these values are set, the Tenant process pushes this information to
the Equipment MIB at the appropriate node(s).
In addition, the Tenant process uses the Tenant OAM MIB to report any status information
about the tenant, such as hardware faults and RAN location information, which is gathered
from the Equipment MIB’s at the Hub/RAN nodes.
