Configuring the Modem

The modem obtains some operating characteristics from jumper settings. The default jumper settings are for common 4-wire full-duplex applications. To reconfigure the modem for 2-wire half-duplex and special applications, you must change the default jumper settings.

To change jumper settings, push the two tabs on the back of the modem to open the modem cover and gain access to the jumper settings on the printed circuit board (see Figure 2-3). Then set the jumpers to the desired settings and replace the cover.

Figure 2-3. Gaining Access to the Modem Jumpers

Figure 2-4 on the next page shows the location of the modem jumpers. Table 2-1 on page 13 summarizes the jumper settings (default settings are bold).
