SCbus Routing Example Overview
In this example, an analog call answered by a D/160SC-LS analog device is connected to a loop-start line interfaced to a VFX/40ESC analog device. To make this connection, full duplex communications are established between analog channel 6 on the D/160SC-LS board and analog channel 2 on the VFX/40ESC board. See Figure 2 for the SCbus routing connections as established at system initialization. Since these boards interface to the telephone network via analog devices, signaling events are handled by the on-board voice device and are not transmitted over the SCbus. Thus at system initialization, default routing established full-duplex communications between each analog device and its associated voice device (on a one-to-one basis) as shown in Figure 2.
