All the infrastructure devices can be supervised with the SNMP or TR-069 pro-

tocols using tools used for retrieving information (throughputs, status of the inter-

faces, temperatures, binary error rate, and so forth) and to trigger threshold alarms.

The HP OpenView tool, for example, is used for centralizing the fed back SNMP

data.

For the purely PLC parameters of the network devices, it is necessary to use

tools specific to each deployed technology. For example, the DS2 products have the

OMS-PLC tool developed by the Dynamic Consulting International company used

for managing the supervision of a DS2 technology distribution network.

Configuring the Network

As we have seen, various technologies can be used to build a PLC distribution net-

work; it is up to the prime contractor team to choose the technology best suited to

the architecture requirements.

The example of a complete architecture for distribution network of a commu-

nity illustrated in Figure 12.13 includes the following elements:

•

IP networks upstream of the PLC network with the DataCenter, which groups

authentication, address, and name servers; and the NOC, which deals with

the supervision and administration of remote networks, like PLC distribution

networks.
