Table 2-2 lists jumper settings for the Model 3610
DSU. Figure 2-2 shows the location of these switches and
jumpers on the DSU circuit card. The jumpers labeled J14
through J16 are for factory testing only and must not be
changed. They should remain in the positions shown.
Two additional hardware straps, labeled J12 and J13,
control the Test Mode Indication feature for the V.35 and
EIA-232-D/V.24 DSU interfaces, respectively. When
enabled (as shown in Figure 2-2), V.35 lead NN and
EIA-232-D/V.24 Pin 25 go to ON (+EIA level) during
Test mode. When disabled, the leads are not connected
internally. The indicator lead for each interface can be
enabled or disabled independently.
