Re: Security control in DSL access network

At the very least, you're making a big assumption here, and that is that there are no EMS in charge of managing configurations and no provisioning system to trigger and not triggering EMS configuration management. In effect, service provisioning doesn't exist in what you describe.Being able to provision over point-and-clicks does not get away with the rest of the configuration. I know you can do (depending on the EMS) a certain types of security configurations. Personally, I haven't seen an EMS capable of do a very good hardening of the configurations of DSLAMs and CMTS's.
Btw, if you don't mind, please point out to me a large scale deployment that actually has 10's of thousands of live customers on a single DSLAM or which DSLAM you propose this is even physically possible, as well as anticipated engineered bit rates for such a deployment.1) Point out? I know but I can't. This is a public list and I would get fired if I discuss in public anything from a client with name. But believe me when I say _it does_ exist.
2) Well with a over subscription you can do it on the Junipers E Series (and I've seen it).
It is on the technical docs of the ESeries but you can also see it in this URL: (http://www.thinkjuniper.net/isp/information.asp?page=239)
3) It is not a configuration I will ever recommend; but sometimes due to budget restrictions of what a provider set to spend for the servicing of a location, the provisioning division just "make it work" doing this.
