N is fixed to 70. The selection of one specific input time-slot is possible by writing the connection
memory (CM) as shown below.
Table 16
Programming Input and Output Lines and Time-Slots in Space Switch Mode
In CM address 00 – 3F: D8 – D4 (SM addr.)
In CM address 40 – 7F: D8 – D4 (SM addr.)
In CM address 80 – BF: D8 – D4 (SM addr.)
In CM address C0 – FF: D8 – D4 (SM addr.)
In space switch mode the leading edge of the SP pulse must be applied with the first bit of time-slot
125. The input and output time-slot number must match.
