Internal Components
The Model 711-102 and 7115-102 Subsets contain one internal component, the subset termination PCBA.
This assembly routes the signals of the handset, party-line selector switch, and hookswitch to the subset
cable.
Block Diagram
The handset, hookswitch, party line switch (Model 7115-102 only), and auxiliary input (optional) signals
connect to the subset termination PCBA (see Figure 3). The subset termination PCBA then connects
these signals to the appropriate terminals of the subset cable for connection to the amplifier/amplifier
enclosure.
