DSP Peripheral Interface
The function of the DSP shown in Table 5.5 is processed through the PCM highway. The PCM highway is connected with a local
highway (2.048Mbps) of the ASIC (IC2) through the McBSP(Multi-Channel Buffered Serial Port) and the control system is con-
nected with the CPU (IC1) local bus through the HPI-8 (Host Port Interface) of the DSP.
See the DSP Data Sheet for the detailed specifications of the McBSP and the HPI-8.

Local Highway Interface Function
This card has the local highway in the speed of 2.048Mbps and local TSW (ASIC (IC2) internal module) to switch from the call
channel (Bch) extracted from E1 line by the E1-IC (IC302), to H.100 interface.
As the switching function inside the DSP is used for the in-band signaling detection by the DSP (IC303), there is no assignment
directly on the local highway map, but the operation is synchronized with the local highway in timing.
