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.
