War Dialer
Before THEnet can implement and operate the dial NMS, several design parameters must be defined by
the network engineers and operators.
Each dial POP requires enough IP address space for the POP to grow to its maximum size. For THEnet,
each POP must support up to 50,000 lines. Therefore, an entire class B network is initially assigned to
each POP.
Modems
Clients
To simplify IP address management, each POP uses a similar IP subnetting plan.
Authenticates, authorizes, and accounts for dial access
clients in each POP by using RADIUS.
Authenticates, authorizes, and accounts for router
administrators in the NOC by using TACACS+.
Uses AAA accounting records to collect performance
data, fault data, and track router configuration changes.
Runs performance tests by using a dial simulator and
client PCs.
