In the past the ISP simply needed a nice big ATM pipe to the ILEC for DSL service. The ILEC provided a PVC from the customer endpoint to the ISP. As understand it this is no longer the case, but only because of non-technical issues.
The non-technical issue is *COST*!!!!! No one considered to use so expensive ATM as L2 for DSL unbundling, at least in Japan, which made DSL in Japan quite inexpensive.
We currently use XO, Covad, etc to connect to the customer We get a fiber connection to them and the provide use L2 connectivity to the custom endpoint using an Ethernet VLAN, Frame Relay PVC, etc complete with QoS. I assume XO, etc use UNE access to the local loop. There is no reason a Muni can't do something similar.
Muni can. However, there is no reason Muni can't offer L1 unbundling. Masataka Ohta
