1. In a cellular mobile data communications system comprising at least one base station, a mobile station having a communications receiver including a modem with an adaptive equalizer, and means for establishing a wireless communications link between the mobile station and a first base station, a method comprising the steps of:

  • receiving at the modem user data communicated from the first base station across the wireless communications link;

    detecting at the mobile station a blank and burst sequence associated with an order from the first base station;

    during the blank and burst sequence, ceasing to receive at the modem user data communicated from the first base station across the wireless communications link; and

    following the blank and burst sequence, again receiving at the mobile station, without retraining the adaptive equalizer of the modem, user data communicated from the first base station across the wireless communications link.
