The data signals for all the accessories are generated on CPU224, and then
transmitted to MS224 CPUKON via MS224 CPU-FC. CPU224 also receives the
speech signals - A (ring) / B (tip) - for extension 1111 through the BPL224
backplane and passes them to MS224 CPUKON card via MS224 CPU-FC. The
following table illustrates the pin-out of the MS224 CPU-FC Flat Cable:

There is a LED on the front panel of CPU224 and another one on MS224
CPUKON. During normal operation they blink continuously. During a Reset or a
Parameter Download they remain on. So, the state of the system can be monitored
by way of these LEDs.
