A communication terminal apparatus receives a management signal at a bit rate A and a data signal at a bit rate B (B>A) through the same line, and includes a band limiting unit, a signal regenerating unit, a timing controlling unit, and a data signal obtaining unit. The band limiting unit limits a band. The signal regenerating unit regenerates a signal having the bit rate A or the bit rate B. The timing controlling unit controls timing for obtaining a data signal based on a signal having the bit rate A. The timing controlling unit controls the band limiting unit to limit the band on receipt of the management signal and to lessen band limitation on receipt of the data signal. The data signal obtaining unit obtains the data signal from a signal having the bit rate B according to the timing control.
