In a point-to-multipoint system, at the hub a split-path topology is used and traffic in the Forward
Link and Return Link directions may be processed by different SLM-5650A modems.
Figure E-7 shows a typical Hub Data Traffic Network for one Layer 2 Network ('P1/P2/A'
shown in red). The other two networks ('P3/P4/B' shown in blue and 'P5/C' shown in green) can
be used in a similar fashion.
Note that the Hub Demodulators used in this configuration are SLM-5650A modems configured
for operation with the optional 'Demodulator only' FAST Feature enabled.
