Routing The MADI card transfers the MADI input signal to the TDM bus, and the
MADO card converts the TDM bus signal to the MADI format. Without
external control, the channels will transmit the signals in the MADI data
stream and on the TDM bus in the same sequence. When using the RS485
interface it is possible, however, to arbitrarily change the allocation on the
MADO card (application e.g. in Route56).

The same frames can be used for MUX and DEMUX units. The 19” frames
have a height of 3U and are equipped with backplane, two power supply
units (+5 V, ±15V), and a connector panel with supply and control connec-
tors.
The D19m series cards are plugged to the backplane. On the rear side of the
backplane, connectors for the power supply, the audio and control signals
can be found. Apart from the supply, also the clock, synchronization, and
control signals are distributed. A jumper determines for each card whether it
is linked to the TDM bus or operating in standalone mode.
