Figure 5-2.Typical Stand-Alone Modem Pool (No D-Lead Control)

In Figure 5-2, the modems and data modules are typically the models that are contained in their own housings and placed on shelves or on top of other cabinets. However, they could be the rack-mounted versions where they are cabled as stand-alone modem pools (no D-Lead). Stand-alone modem pools are usually dedicated for a particular application.

Figure 5-3, DCP Mode 2 Network (Modem Pooling), shows a DCP Mode 2 network where the switches are either System 75, System 85, Generic 1, Generic 2, or Generic 3.
