As shown in Figure 4, the handset, hookswitch, party line switch (Model 7165-102 only), and auxiliary
input (optional) signals connect to the Subset Termination PCBA. The Subset Termination PCBA then
connects these signals to the appropriate terminals of the subset cable for connection to the
amplifier/amplifier enclosure.
