Configuration: Fractional T1 Configuration Using PPP
This section provides step-by-step instructions for configuring the HSIM or CyberSWITCH to use
a fractional T1 circuit in a PPP environment. This example assumes the setup shown in
a fractional T1 circuit in a PPP environment. This example assumes the setup shown in
using two CSX400s with each containing a HSIM or CyberSWITCH. 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.
