DTE as DSR or RI (JB6 & JB7)

Because this rear card is designed to function in more applications

than the Model 1004ARC, this jumper must be installed only in one
position. Place the jumper across pins 1&2 so that the terminal (DTE)
sees DSR as high when the DTE raises DTR. The other positions,
across pins 2&3, are for Ring Indicate as defined by EIA/TIA-561. The
RI function is irrelevant (and on the Model 1004ARC is also discon-
nected) and can cause improper operation if the jumper is installed
incorrectly.

JB6 & JB7

Position 1&2  =  DSR
Position 2&3  =  N/A

4.0  INSTALLATION

This section describes the functions of the Model 1000R16 rack

chassis, tells how to install front and rear Model 1004ARC cards into
the chassis and provides diagrams for wiring up the interface connec-
tions correctly.

4.1  THE MODEL 1000R16 RACK CHASSIS

The Model 1000R16 Rack Chassis (Figure 5) 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.

WARNING!

There are no user-serviceable parts in the

power supply section of the Model 1004ARC. Voltage set-
ting changes and fuse replacement should only be per-
formed by qualified service personnel. Contact Patton
