The invention relates to a circuit arrangement for forming the termination of
an analogous subscriber line which comprises a first connection and a second connection
for connecting a twin-wire analogous subscriber line. Said first connection is
linked with said second connection via a series connection of a first capacitor,
at least one first adjustable resistor and one second capacitor. According to the
invention, a direct current source is linked with the first point of linkage of
the first capacitor and the first adjustable resistor. Said direct current source
impresses a current which serves to adjust an operating point for voice and data
transmission via the analogous subscriber line. The first and the second capacitor
block equisignals on the subscriber line so that no direct current can flow via
the analogous subscriber line.
