This section provides step-by-step instructions for configuring the WPIM-T1/DDS to use a fractional T1 circuit in a PPP environment. This example assumes the setup shown in Figure 3-7using two CSX400s with each containing a WPIM-T1/DDS. Configurations may vary depending on the host platform. In a fractional T1 setup, only a portion of the 24 Timeslots or DS-0s are used.
