DTE/DCE/Fiber mode
Each serial port can be configured to connect to a terminal (DTE
equipment), a modem (DCE equipment), or a Fiber Superloop Network
card. Instructions for setting the switches SW2, SW3, SW4, SW5, SW6,
SW7, SW8, and SW9 are shown in Table 324 "NT8D41BA DTE/DCE/Fiber
switch settings" (page 827). Figure 270 "NT8D41BA QSDI paddle board"
(page 823) shows the location of these switches on the paddleboard.
