Figure 7.7 SSP and SCP Test Signals
7.3 Serial Interface Bus
The 192 Kbps S/T interface signal consists of two B channels (64 Kbps each), one D channel (16
Kbps) and other control signals. The multiplexing/demultiplexing functions are carried out in the Serial
Interface Bus (SIB) block. In addition, the B1 and B2 channels can be individually set to carry 64
Kbps or 56 Kbps traffic.
7.4 B Channel Switching
Each B channel in S/T bus can be individually programmed to connect to one of the three data ports:
B channel HDLC controller , PCM port 1 or PCM port 2. In addition, the PCM ports can be
programmed to connect to the B channel HDLC controller for voice recording/ retrieving from main
memory in answering machine applications. In this case, only extended transparent mode can be
used.
The switching matrix is controlled by PXC bit in PCTL register and BSW1
0 bits in B1_MODE and
B2_MODE registers as follows:
B1
01
A special mode is provided (BSW1
0 = 11B) in which case the PCM port can receive data from layer
1 and the HDLC receiver can receive data from PCM port simultaneously.
