3.2 CONFIGURATION STRAPS 3.2.2 Location of the Internal Straps In addition to the configuration switches described above, the Model 1075 is also equipped with two internal straps that set the DTE/DCE Configuration and the DB-15 Shield. In order to configure these straps, you must open the Model 1075 case. Figure 5 (below) shows the location of the DCE/DTE switch and the JP1 strap on top side of the the PC board.
4.0 INSTALLATION 3.2.4 Setting the JP1 Shield Strap The setting of JP1 determines whether the shield (pin 1) of the X.21 interface is connected signal ground.

When connecting two Model 1075s, it is necessary to use a "crossover" cable. The diagram below shows how a cross-over cable should be constructed for an environment where both Model 1075s use a 8wire RJ-45 connector. Similar logic should be followed when using RJ11 connectors or a combination of the two. 4.3 AC POWER CONNECTIONS Power is supplied to the Model 1075 by a 9 VDC, 1 A wall mount transformer. This transformer connects to the Model 1075 by means of a cannon jack on the rear panel.
5.0 OPERATION 5.2 TEST MODES Once the Model 1075 is properly configured and installed, it should operate transparently—as if it were a standard cable connection. Section 5.0 describes the LED status monitors and the built-in V.52 and V.54 test modes. The Model 1075 is powered by a 9V DC external wall mount transformer. To power up the unit, connect the power supply cord to the power jack on the rear of the Model 1075 and plug the power adapter into the wall. There is no ON/OFF switch. 5.
APPENDIX A C. If the BER test equipment indicates a fault, and the Local Analog Loopback test was successful for both Model 1075s, you may have a problem with the twisted pair line between the modems. You should then check the twisted pair line for proper connections and continuity. 5.2.3 How to Use the V.52 BER Test Independently The V.52 BER test can be used independently of the V.54 loopback tests.
