Abstract: 1. A process for matching a termination amplifier circuit to a telecommunications line, in which the termination circuit (G, G1), whose bidirectional main branch is connected to the telecommunications line, is terminated at the side opposite the main branch by a balancing circuit containing adjustable impedances ; each secondary branch (AC, CA) of the termination circuit (G, G1) containing an amplifier (V1, V2) ; the two secondary branches (AC, CA) being coupled together at their ends away from the termination circuit (G, G1) ; a test signal being applied to one secondary branch (AC) of the termination circuit ; the portion of the test signal level passing through to the other secondary branch (CA) due to the termination transition damping being continually measured ; the adjustable impedances being adjusted, before the measurement, in a previously specified manner, to a different value ; the signal levels of said passing through portions of successive test signals being compared with each other and the corresponding impedances calculated ; the measurements being repeated a previously specified number of times, after which the balancing circuit is adjusted to the impedance corresponding to the least signal level in said pass-through portion of the test signal, and fixed at this adjustment, characterised in that throughout the matching process the secondary branch (AC) of the termination circuit (G, G1) which carries the outgoing signal is interrupted at a point (S1) between the termination circuit (G, G1) and the amplifier (V1) ; said passing through portion of the signal level being measured ahead of the interruption point (S1) ; a test signal of constant level being fed to the same secondary branch (AC) following the interruption point (S1) ; so that the test signal flows through the amplifier (V1) in this secondary branch (AC) and through the coupling (G1, LM) to the other secondary branch (CA) and then through the amplifier (V2) in the other secondary branch (CA) back to the termination circuit (G, G1).
