Overview
The customer and management domains logically comprise the network model.
This chapter describes the components that comprise these domains.
Customer Domain Components
The primary purpose of the customer domain network is to provide IP routing of
customer data between the Internet Service Provider (ISP) and the end-user
system (ES).
The basic customer domain configuration consists of the following components:
 An end user (PC or workstation) or multiple users on a subnet connected to
the HotWire 5446 RTU, which in turn, is connected to one of the DSL card
ports of the HotWire DSLAM
 The 10BaseT port of the HotWire DSLAM DSL card connected to a router
that may also reside in the Central Office (CO) or wire center
 The router is then connected to the ISP typically over a Wide Area Network
(WAN)
 The ISP may also be directly connected to the same LAN as the DSL card
