By default, the device on the AUX port is assigned the network address
192. 1 68.0.0 with a subnet mask of 255.255.255.0. If there is a network address
conflict with a device on the Ethernet port, the network address of the device on
the AUX port is automatically changed to 192. 1 68. 1 .0.
In the illustration, one fax machine is connected to each pair of ports to illustrate
that only one T.38 connection is supported by each of the four pairs of RJ-11 ports.
Up to four fax machines can be connected to the SPA8000 router, but they must be
distributed as shown.
