Overview
The service and management domains logically comprise the network model.
This chapter describes the components that comprise these domains.
Service Domain Components
The primary purpose of the service domain network is to provide IP routing of
customer data between the Network Service Provider (NSP) and the end-user
system (ES).
The basic service domain configuration consists of the following components:
An end user (PC or workstation) or multiple users on an Ethernet LAN
connected to the HotWire 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 or
switch that may also reside in the Central Office (CO) or wire center
The router or switch is then connected to the NSP typically over a Wide Area
Network (WAN)
The NSP may also be directly connected to the same LAN as the DSL card
