      no, that's wrong, read:
      1) Data transmission + (10, 100baseT, 1000)
      2) Data transmission - (10, 100baseT, 1000)
      3) Data reception + (10, 100baseT, 1000)
      4) R/Data transmission + (1000)
      5) R/Data transmission - (1000)
      6) Data reception - (10, 100baseT, 1000)
      7) E/Data reception + (1000)
      8) E/Data reception - (1000)
      and this is just for ethernet, RJ45 can also be used for telephony (digital and analog), token ring, ATM25, G703 .... and others.
