The MUNICH32 is designed to handle up to 32 data channels of a PCM highway. It
transfers the data between the PCM highway and a memory shared with a host
processor via a 32-bit P interface. At the same time it performs protocol formatting and
deformatting as well as rate adaption for each channel independently. The host sets the
operating mode, bit rate adaption method and time slot allocation of each channel by
writing the information into the shared memory.
Using subchanneling each time slot can be shared between up to four MUNICH32s; so
that in one single time slot four different D-channels can be handled by four MUNICH32s.
Figure 4, Figure 5 and Figure 6 give a general overview of system integration of the
MUNICH32.
