DSL over DLC or NGDLC is not only possible, but may become the architecture of choice, with a fiber trunk (instead of multiple T1s) between the CO and the NGDLC.

Re: NGDLC and DSL Deployments PaperChase, DLC equipment is a part of getting ADSL to some customers. Most customers, I think, are located out of range of ADSL speeds so the telco is forced to spend money on installing Next Generation DLC (NGDLCs) in order to bring the fiber closer to the customer. The article is correct. DLC have to be replaced by NGDLCs. That is what Bernard is referring to. We talked about this pretty extensively upstream. Try: Message 10301456 Installing NGDLC's isn't the only thing needed to be done for ADSL services. I thought the king of DLCs was Realtec. Which was purchased by GEC, Plc and now is called Marconi. Then I thought Lucent may be, then I thought Advanced Fiber (AFCI) may be, etc....I spent a lot of time trying to figure that one out and unfortunately, I never did. It was pretty confusing. At least to me. I believe that the NGDLC has to be of the same manufacturer of the DLC it has to replace because of compatibility problems with the CO. And I thought an outright NGDLC addition between the home and the CO also had to be compatible with the switching equipment already installed in the CO. But now I'm not sure.

Fiber-optic lines will connect these stations to 1,400 SBC central offices, at cost of $1.7 million per central office. cnetinvestor.com
