I was on a service call and was speaking with a FP line tech who I know somewhat well. He told me that FP is going to be rolling out bonded ADSL2+ service soon. Not sure what soon means. He saw paperwork at the office describing the service and probably also how to install it. I believe it will only be offered in towns where the CO is equipped with an Adtran TA5000 DSLAM. (same equipment used for their Ethernet over Copper service, if I am not mistaken)

How one would figure out if they are served from a TA5000-equipped CO without asking a local tech, not sure.

They'll bond more than 2 lines, but that isn't ADSL2+. That's their Ethernet over Copper service. You'd need a bunch of lines to get 100Mbit EoC. The tech mentioned he thought max per line was 5Mbit on their EoC, under good loop conditions. My guess is a lot less than that per line, like 2.3Mbit max. So you'd need a 50 pair copper drop installed. At that point it makes no sense, and they'd run fiber direct.
