摘要：
A frequency division multiplexed coupler (401) for multiplexing a plurality of signals onto a single telephone wire (636) is disclosed. The frequency division multiplexed coupler (401) comprises a first modulating unit (621) for modulating a frequency of a first outgoing signal to a first modulated signal having a frequency range corresponding to a first carrier signal (601). The frequency division multiplexed coupler (401) further comprises a second modulating unit (622) for modulating a frequency of a second outgoing signal to a second modulated signal having a frequency range corresponding to a second carrier signal (602). A frequency multiplexer (635) is coupled to the first modulating unit (621) and the second modulating unit (622) for multiplexing the first modulated signal and the second modulated signal onto a single telephone wire (636) for transmission to a remote site.
