*Estimated 8-Pair Downstream Rate (Mbps) =           Estimated rates assume:
          1) No AMI or B8ZS in cable
          2) 12 self crosstalk (vectoring = no)
          3) MinINP = 2, SNR Margin = 8

    *If the background color of the calculated value is red, the backhaul loops are too long to support the required Network capacity.

**ADTRAN predicts an average per-subscriber busy hour load of 1.7 Mbps for CAF-rate services in the year 2020. The selector provides the required network
    capacity at that value and twice that value (3.4 Mbps). Vectoring gain assumes full FEXT removal via SLV.
