FRACTIONAL E1 CONFIGURATION USING PPP
This section provides step-by-step instructions for configuring the WPIM-E1 to use a fractional E1
circuit in a PPP environment. This example assumes the setup shown in Figure B-6 using two host
platforms, each containing a WPIM-E1. In a fractional E1 setup, only a portion of the 32 timeslots
or DS-0’s are used.
Figure B-6 Fractional E1 Configuration
The line configuration information shown in Table B-2 must be supplied by the service provider.
NOTE
The terms DS-0 (Digital Signal, level 0) and timeslot are used synonymously in this
guide to represent a standard 64,000 bit/second channel.
