Training the line comes from the days of analog modem connections. Remember the long sequence of hisses, beeps, and just some other plain wierd sounds after the dialing of the modem?

Training the line means to negotiate the best possible speed on the line. Sometimes, line noise can interfere with normal DSL line traffic, so, the modem must negotiate the best possible speed despite the noise.

With the noise, the best speed can't be offered, so, it throttles the speed back through a negotiation sequence so that you can get the best speed and connection stablility despite the noise.
