I showed the questioner the table of substitutes, where everything is "as on the tray". The jumpers are mentioned in the instructions for the new uniphone. Another issue is calling, which will not work in the new one, and in the old one it did not work, only adding the generator plate (visible in the upper part of the old uniphone) caused the calling (heard in the uniphone receiver). It follows that a DC trigger is in the block and a buzzer is required. The generator just added is a better version of such a buzzer. In the new uniphone it should be connected as it was in the old one.
I will only suggest that the generator has three cables. One is power, the second is ground and the third is the signal output. In a typical multi-wire intercom installation, a calling signal appears on one of the cores, which goes to the uniphone receiver. In this case, a DC voltage appears on this vein. To use them, you need to give this cable to the generator board, connect the mass of the generator board to the ground of the uniphone (i.e. two wires will be after the MASS terminal) and the "signal" cable coming from the generator board should be given to the RING terminal.
