3.0 Hardware Description
3.1 Block Diagram
Figure 3-1 illustrates a block diagram of the evaluation board. It includes four
Bt8370 circuits, receive and transmit connected (T1 or E1) lines interface, a serial
bus used to transfer data between these circuits, and the Bt8474 (MUSYCC). The
data is transferred between the Bt8474 and the host through the Peripheral
Component Interconnect (PCI) bus. The Bt8370 circuits are configured and
controlled using the Expansion Bus (EBUS).
