Configuring DIP Switch S1 DIP s witch S1 is where you configure the data r ate, asynchronous or synchronous data f ormat, transmit clock source, and response to RDL request. The f ollowing tab le summarizes def ault posi[...]

10 Note When setting the 1082 for SNMP Management, the DTE r ate switches (S1-1,S1-2, and S2-1) m ust be also set to the ON posi- tion. Theref ore , to set a 1082 unit SNMP Mangagement mode, the follo wing s witches ha v e to be at the ON position, S1-1, S1-2, S2-1. Switches S1-1 and S1-2: Data Rate Use s witches S1-1 and S1-2 to configure the asy[...]

11 Switch S1-4: Must be set to the ON position (Reser ved). Switch S1-5: Asynchronous/Sync Operation Use s witch S1-5 to configure the Model 1082 f or async/sync operation. Switch S1-5 must be set in the Off position. There is no other v alid set- ting. Switches S1-6 and S1-7: System Clock Mode Use Switches S1-6 and S1-7 to configure the 1082 or [...]

Y ou must first set the units to 128 kbps or slower to use the RDL. Configuring DIP switch S2 Use the eight DIP s witches in S2 to enable 19.2 kbps or 144* kbps syn- chronous operation and set the lo[...]

13 Switches S2-1: 19.2 kbps or 144* kbps Synchronous Rate Enable Use s witch S2-1 to allow the Model 1082 and Model 1082/144 to operate at the 19.2 kbps synchronous data rate, or to enab le the Model 1082/144 to operate at the 144* kbps synchronous data rate . Note T o operate at 19.2 kbps or 144 kbps, set s witches S1-1 and S1-2 to the OFF positio[...]

14 Switch S2-6: Response to RDL Request from DTE Use s witch S2-6 to deter mine the Model 1082 response to RDL requests from the local DTE. In the enabled setting, the 1082 responds to RDL requests from the local DTE by sending an RDL loop request to the remote Model 1082 (See “Remote Digital Loopback (RDL)” on page 23). Switch S2-7: Compatabil[...]

15 4.0 INSTALLATION Once the Model 1082 has been configured, it is ready to connect to the twisted pair interf ace, to the serial por t, and to the power source . This section tells you ho w to make these connections . Figure 4. Model 1082 or Model 1082/144 rear view 4.1 CONNECTING THE T WISTED PAIR INTERFACE The Model 1082 suppor ts communication[...]

16 The RJ-45 connector on the Model 1082’ s twisted pair interface is polar- ity insensitive and is wired f or a two-wire interface . The signal/pin rela- tionships are shown in Figure 5. Figure 5.

17 designed to connect to DTE equipment, such as a router . How e ver , tail- circuit applications require connection to another DCE equipment, such as a multiple x er (see Figure 7). When connecting the V .35 interface of the Model 1082 to your DCE de vice , use a V .35 null modem cable. Some applications ma y also require the installation of a V [...]

18 multiple x er. When connecting the X.21 interf ace of the Model 1082 to your DTE de vice, use a X.21 str aight through cab le (see Figure 8). Figure 8. Connecting the Model 1082 to X.21 DTE or DCE T o change the DCE/DTE or ientation from the default position (DCE), y ou must open the case Model 1082 case. Opening the Case T o open the Model 1082[...]

19 The DCE/DTE strap is located on the top side of the 1082 PC board (see Figure 10). The arrows on the top of the str ap indicate the configuration of the X.21 por t (for e xample, if the DTE arrows are pointing tow ard the DB-15 connector , the X.21 por t is wired as a DTE). Change the DCE/ DTE orientation by pulling the strap out of its soc ket[...]

20 The Model 1082 powers up as soon as it is plugged into an A C outlet-- there is no power s witch.The Universal A C supply is equipped with a male IEC-320 DC P ower The 36-60 VDC DC to DC adapter supplied with the DC version of the Model 1082 plugs in a DC source (nominal 48VDC) and plugs into the barrel power supply jac k on the rear of the 1082[...]

21 5.0 OPERATION Once the Model 1082 is properly configured and installed, it should oper- ate transparently . This sections describes power-up , reading the LED status monitors, and using the b uilt-in loopback test modes . 5.1 POWER-UP T o apply power to the Model 1082, first be sure that you ha v e read “Con- necting P ower” on page 19, an[...]

22 5.3 T EST MODES The Model 1082 off ers two proprietar y loopback test modes , plus a built- in V .52 BER test patter n generator , to ev aluate the condition of the modems and the communication link. These tests can be activ ated ph ys- ically from the front panel, or via the interf ace. Local Line Loopback (LLB) The Local Line Loopback (LLB) te[...]

23 Remote Digital Loopback (RDL) The Remote Digital Loopback (RDL) test chec ks the performance of both the local and remote Model 1082s, and the communication link betw een them. Any characters sent to the remote Model 1082 in this test mode will be returned back to the originating device (see Figure 14, below). F or e xample, characters typed on [...]

24 Using the V .52 (BER) test pattern generator T o use the V .52 BER tests in conjunction with the Remote Digital Loop- back tests (or with Local Line Loopbac k tests), do the f ollowing: 1. Locate the 511/511E toggle s witch on the front panel of the Model 1082 and set the toggle to the down position. This activ ates the V .52 BER test mode and t[...]
