Broadband network architecture


I'm doing a study on broadband access. Can anyone guide/direct me to obtain info. on broadband Network Setup/Architecture ?? Basically, knowing the setup of the core network until the last mile access using various connection and ways( eg. wireless/cable). Need not to be vendor specific (something in general).
Have anyone come across anything like this or more less equivalent ??

Most of the broadband info. i've got are on business, news and definition, none on the technical/network setup.

Pls. help..

Thank You.

Introduction and Overview of Communication Systems
Broadband Network Architecture:

That is a very open-ended question!

The main places to look are:-

the equipment manufacturers

Alcatel networks will give you a good info.

The basic answer for DSL is:-

Phone line to CO
In the CO the line is attached to a DSLAM
The DSLAM is connected to the Telcos network - usually ATM
The ISP will take a feed of f the Telcos ATM network - This is usually 34-155mb
This is attached to a large Cisco gateway router
This router will provide Radius and other services such as the allocation of IP addresses
The router is connected to the ISPs core network.
here you will find all the usual suspects such as email servers, apps servrs, news etc. These and cusomer subscriptions etc will be controlled by an OSS application.
The ISP will have a fat pipe to the Internet for external traffic.
The DEVIL is in the cost of support rather than the equipment.

Hope that helps
