Overview

The carrier-mounted Model 3811 modem (Figure 3-1) is capable of dial or 4-wire/2-wire leased-line operation and installs into a COMSPHERE 3000 Series Carrier. The Model 3811’s faceplate has 16 LED status indicators for displaying modem activity and an audio speaker jack for the carrier’s optional speaker.

The Model 3811 modem’s rear has two DTE edge card connectors that mount into a connector plate located on the rear of the carrier. This connector plate has two DB-25-S connectors, one providing an EIA RS-232 DTE interface and one providing an EIA RS-366A DTE interface. The Model 3811 derives ac power from the COMSPHERE 3000 Series Carrier’s backplane which is a common bus to all devices installed in the carrier. The user interface to any Model 3811 is through the shared diagnostic control panel (SDCP), an optional feature

similar to the DCPs on the Model 3810 and Model 3820. For a better understanding of DCP operation, refer to Chapter 4, DCP Operation.

The COMSPHERE 3000 Series Carrier has a total of

17 slots. The first slot, Slot 0, is reserved for the Shared Diagnostic Unit (SDU) while the remaining 16 slots can house up to 16 Model 3811 modems, or for mixed networks, a combination of Model 3811 modems and Model 3611 Data Service Units (DSUs). An SDU is a circuit card that provides SDCP and network management interfaces to modems and DSUs installed in the carrier. SDUs are only required if a single SDCP is used by multiple COMSPHERE 3000 Series Carriers in a cabinet or if a network management system (NMS) is used.

For more details on the COMSPHERE 3000 Series Carrier, refer to the COMSPHERE 3000 Series Carrier, Installation Manual.
