I have just moved over to 21CN and have a query about the training phase.
I asked my ISP's support desk whether I should leave my router connected all the time, or reboot it once a day, as was the case during the training phase for 20CN MaxDSL. They advised leaving it up all the time. However, I'm puzzled by this, because I can't see who the exchange is going to figure out what the maximum speed for my line is, if it never has the opportunity to resync and attempt faster speeds.
The line is currently sync'ed at 12999 Kbps downstream, but I think the link ought to be capable of better than this (previously, I was getting 8128 Kbps with 28 dB of Attenuation and a noise margin of 10 dB).
So the question is: should I manually force a resync by rebooting the router, or not?
