DTE as DSR or RI (JB6 & JB7)
Because the Model 2017RC uses DSR (but not RI), only position
1&2 is valid when this rear card is used. Position 1&2 causes the
terminal (DTE) to see DSR when the Model 2017RC is powered up
properly. Position 2&3 is for Ring Indicate, which is not used on the
Model 2017RC. Furthermore, use of position 2&3 will cause DSR to
float, which will lead to improper operation of the Model 2017RC.
JB6 & JB7
Position 1&2 = DSR
Position 2&3 = Not a Valid Setting for Model 2017RC

4.0 INSTALLATION
This section describes the functions of the Model 1000R16 rack
chassis, tells how to install front and rear Model 2017RC cards into the
chassis and provides diagrams for wiring up the interface connections
correctly.
4.1 THE MODEL 1000R16 RACK CHASSIS
The Model 1000R16 Rack Chassis (Figure 6) has sixteen short
range modem card slots, plus its own power supply. Measuring only
3.5” high, the Model 1000R16 is designed to occupy only 2U in a 19”
rack. Sturdy front handles allow the Model 1000R16 to be extracted
and transported conveniently.
4.1.1 THE RACK POWER SUPPLY
The power supply included in the Model 1000R16 rack uses the
same mid-plane architecture as the modem cards. The front card of
the power supply slides in from the front, and the rear card slides in
from the rear. They plug into one another in the middle of the rack.
The front card is then secured by thumb screws and the rear card by
conventional metal screws.
