1. A method for common transmission over multiple line pairs, comprising:
- modulating information to be sent on a signal;
transmitting the modulated signal to a receiving device over the multiple line pairs;
wherein, a transmission spectrum of each transmitter in the multiple line pairs comprises a frequency segment that meets a bearer condition of the modulating, and a frequency segment that does not meet the bearer condition of the modulating;
the number of the multiple line pairs is N, N is greater than or equal to 2; and
dividing the information to be sent into N+M parts, wherein, the N parts of the information to be sent are carried on frequency segments of the N line pairs that meet the bearer condition, the M parts of the information to be sent are carried on at least two frequency segments that do not meet the bearer condition, wherein M is greater than or equal to 1.

Abstract
The present disclosure discloses a method for common transmission over multiple line pairs, and a transmitting device and a receiving device therefor. The method for common transmission over multiple line pairs includes: modulating information to be sent; and sending a modulated signal to a receiving device over the multiple line pairs; wherein, a transmission spectrum of each transmitter in the multiple line pairs comprises two parts: a first part is a frequency segment that meets a bearer condition of a modulation method, and a second part is a frequency segment that does not meet the bearer condition of the modulation method.
