Could someone please recommend some good books for the track below. Core/Pop technologies ,DSL, Dial, Cable, Wireless, or Optical. Elements of WAN Switching and Dial. It is for the new track Cisco will be offering as a beta. I would like to get some books before hand to study on so that I don't miss the boat.
