b. Signal Connections for Normal Operation (figure 2-2). Connect the modem's input/output (I/O) cable assembly to
either A5A1J5 or A5A1J6 on the rear panel assembly of the encoder-decoder. (A5A1J5 and A5A1J6 are wired in parallel
so that either can be used.) The signals and their pin connections for the input/output connectors are listed in table 2-4.
