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.
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. -----Original Message----- From: Masataka Ohta [mailto:mo...@necom830.hpcl.titech.ac.jp] Sent: Tuesday, February 05, 2013 7:17 PM To: Scott Helms Cc: NANOG Subject: Re: Muni fiber: L1 or L2? > note that a phone company often had > several central offices to cover their territory in the time before > there were remotes (Digital Loop Carriers). Each CO has its own MDF, where competing ISPs must have their routers. No different from competing ISPs using DSL or PON.
