User’s Manual
Frame Processing
During normal operation the processing of a frame comprises three consecutive parts.
During transmission from ISDN to LAN the frame is first processed from the MUNICH32,
then from the CPU and finally from the LAN controller.

Frame Processing
Though the CPU is never idle, its part on frame processing is that between the
MUNICH32 and the LAN controller are active. The time to process one frame is the
minimum delay required between frames during continuous transmission.
