Understanding the Domain Types
Functionally, the HotWire DSLAM network model can be divided into:
 Features supporting customers
Features integral to supporting customers are the DSL cards and HotWire
5446 RTUs.
 Features supporting overall system management
The central point of access for overall system management is the MCC card.
However, the features integral to supporting overall system management are
also distributed throughout the HotWire DSLAM and the HotWire 5446 RTUs.
To monitor and control the operation of the overall system, the IP addresses of
the HotWire DSLAM and the HotWire 5446 RTU must be allocated in such a way
that they are partitioned into two distinct domains.
 Management domain
The management domain resides in a mutually-exclusive domain from that of
the customer domain. The NAP provisions IP addresses for the management
domain.
For more information about the management domain, its features and
components, see Chapters 3 and 4.
 Customer domain(s)
The customer domain (also known as the ISP domain) resides in a
mutually-exclusive domain from that of the management domain. (There
should be one customer domain for each NSP served by the HotWire
DSLAM.) A customer domain encompasses IP addresses in all ISP domains
to which the end-user systems (ES) subscribe.
For more information about the customer domain, its features and
components, see Chapters 2 and 4.
For more information about assigning IP addresses, see Chapter 5.
