Circuit Card Description and Installation
both switches are shown in Table 42. To avoid system problems, switches

For each X, the setting for this switch makes no difference, because it is not used.
DTE/DCE mode
Each serial port can be configured to connect to a terminal (DTE equipment)
or a modem (DCE equipment). Instructions for setting the DTE/DCE
switches SW2, SW3, SW4, SW5, SW6, SW7, SW8, and SW9 are shown in
Table 43.
Example: Port 1 is changed from DTE to DCE by reversing every switch
position on SW3 and SW2; i.e., switches that were off for DTE are turned on
for DCE, and switches that were on for DTE are turned off for DCE.
