Overview of the HotWire DSLAM
Network Model
The HotWire DSLAM and the HotWire 5446 RTU provide high-speed Internet or
Intranet connectivity to a central site from customer premises.
NOTE:
Data rates and distances vary depending on line speed and line conditions
(i.e., the DSL cards measure performance during operation and can adjust
the upstream or downstream rate to match changing loop characteristics due
to temperature, humidity, or electrical interference). For a list of the supported
DSL card data rates, see Appendix C,
Data Rates , of the appropriate
HotWire DSLAM Installation Guide.
The HotWire DSLAM network model can be implemented in a number of ways.
For example:
 A Small Office/Home Office (SOHO) implementation with one or more users
connected to a LAN needing high-speed Internet connectivity to an Internet
Service Provider (ISP).
 A SOHO implementation with one or more users connected to a LAN needing
high-speed Intranet connectivity to the corporate LAN.
 A campus implementation needing internetworking between several sites,
each with a LAN.
The network model for these examples can be partitioned into the following
building blocks:
 Network Service Provider
 Network Access Provider
 Service Subscriber
