In this example, a fax call received by the T-1 device on the first D/240SC-T1 board is connected to the fax device on the VFX/40ESC board. To make this connection, full duplex communications must be established between digital channel 12 on the first D/240SC-T1 board and fax channel 2 on the VFX/40ESC board. See Figure 6 for the SCbus routing connections established at system initialization.
For fax sharing applications, the VFX/40ESC board is setup in resource mode. In this mode, the analog devices on this board are disabled.
