During the microprocessor initialization routine, the
microprocessor should program the desired active
paths through the matrices, and put all other
channels into the high impedance state. Care should
be taken that no two connected ST-BUS outputs
drive the bus simultaneously. When this process is

Applications
Typical Exchange, PBX or Multiplexer
Figure 7 shows a typical implementation of line cards
being interconnected through a central routing matrix
that can scale up in channel capacity to
accommodate different number of ports depending
on the application. In a configuration where the
switched services utilize concatenated or grouped
time slots to carry voice, data and video (channels of
128, 256 Kb/s, ISDN H0 and others), the central
routing matrix has to guarantee constant throughput
delay to maintain the sequence integrity between
input and output channels. Figure 7 shows an
example where the MT89L85 device guarantees
data integrity when data flows from the T1/E1 to the
