Appendix K
K.3.2 Point-to-Multipoint Hub-to-Remotes, Split-path Traffic Using
Switches
With switches used, the hub and remote are on the same subnet as shown in Figure K-9,
meaning that broadcasts will be allowed to transverse the network. Learning Mode must be
disabled on the Hub Tx/Rx modem, because if a computer on the remote sends a broadcast out
to the Hub, the modem learns that MAC is local – when, in fact, it is not.
