This is very similar to the DS0 switching system configuration with CAS described in the
previous section. The only difference is that in this system the global C1FP can be reduced to
every SBI multiframe rather than the longer 48 frame SBI bus signaling multiframe. The
advantage is that there is less latency when making switch configuration changes via the CMP
signals.
