MT89L80  
Data Sheet  
of the line circuit by building signalling logic, e.g., for on-off hook detection, which communicates on an ST-BUS  
output. This signalling ST-BUS output is monitored by a microprocessor (not shown) through an ST-BUS input on  
the bottom MT89L80.  
Fig. 8 shows how a simple digital switching system may be designed using the ST-BUS architecture. This is a  
private telephone network with 256 extensions which uses a single MT89L80 as a speech switch and a second  
MT89L80 for communication with the line interface circuits.
