Its probably in extended version of the old 2-in-one telecom line multiplexer. These old multiplexers, which are still in use in many places, (including big cities) are analog line doublers, where one of the voice signals is mixed up to a higher frequency, and on the other side (in the exchange normally) mixed down again. Using this system, it should be possible to mix multiple voice bands (each about 2.x Khz) on top of each other. ofcourse this requires agressive filtering, and will limit the bandwidth of the voice channel, and therefore the maximum throughput on modem connections.
