Functional Description

Each unit has one or more signal inputs (denoted by I). Most units have at least one

signal output (denoted by S). Any input I can be connected to any signal output S. In

addition to the signals shown in figure 7 there is also the signal S0 (silence), which is

useful at signal summation points. Table 2 lists the available signals within the PSB 4860

according to their reference points.
