Status Indicators

The 3800 Series modems’ status indicators continuously provide information on the modem’s operating condition. All of the status indicators on the Model 3810 and Model 3820 appear on the DCP (Figures 4-1 and 4-2), whereas the status indicators for the carrier-mounted Model 3811 are located on the

Model 3811’s faceplate, the SDCP, and the SDU faceplate (Figure 4-3).

The standalone Model 3810 modem’s DCP has

12 LEDs, and the carrier-mounted Model 3811 has 16 LEDs. These LEDs are listed and described in Table 4-1; LEDs specific to one model type have the appropriate model number shown in the table.
