1.8.2 Connecting the CSMIM-T1 to a Fractional T-1 Line
In a fractional T-1 setup, only a portion of the 24 timeslots or DS-0’s are
used. Some may be routed through the Drop and Insert Port to a PBX, as
in a voice application. Table 1-2 provides a short list of information
necessary to use a fractional T-1 circuit in a PPP environment.
Configurations may vary depending on the hub. The line configuration
information shown in Table 1-2 must be supplied by the service provider.
