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.
That's the old "1+1" type. The later ones deployed are "0+2" where there is no baseband channel (IIRC). When I was out at Riversdale Beach, I had a 2nd line put in for a modem. The installer was about to put in a 0+2, due to scarcity of pairs. I convinced him that this wouldn't work with my modem, so he pinched someone else's line to use as my 2nd one, and put the 0+2 in further down the street. :^) -- Andrew P.
