Could the polarity of tha A and B legs of a line have an impact on the transmit speed of a modem.

For example I rune my modem with A leg 0v and B leg -48v would there be a difference if the legs were reversed

Polarity can not alter communication speed, because the signal modem handles is an alternate sound-wave. Moreover, modem has a transformer at the very first point of connection to the line, making "polarity" a meaningless word.
