UMPERS
For most applications, you don't
need to reset internal jumper
switches. However, jumper switches
must be reset if you need to
connect frame ground to signal
ground, switch from A/A1 control
to MI/MIC control, or use the
modem in a DC rack enclosure.
For detailed jumper information,
see Appendix C.
