Connection Memory Access
For a connection memory access the control byte bits C1 and C0 contain the data bits D9 and D8,
respectively. D9 is the validity bit which together with D8 and the data byte D7 – D0 is written to the
CM address IA7 – IA0.
The function of the validity bit is controlled by STA:TE. D8 – D0 and IA7 – IA0 contain the informa-
tion for the logical line and time-slot numbers of the programmed connection, D8 – D0 for the inputs,
IA7 – IA0 for the outputs. Tables 14 through 18 show the programming of these bits for the different
configurations and modes.
