Device Configuration
The ZL50232 architecture contains 32 echo cancellers divided into 16 groups. Each group has two echo cancellers
which can be individually controlled (Echo Canceller A (ECA) and Echo Canceller B (ECB)). They can be set in
2.1
Normal Configuration
In Normal configuration, the two echo cancellers (Echo Canceller A and B) are positioned in parallel, as shown in
Figure 6, providing 64 milliseconds of echo cancellation in two channels simultaneously.
Figure 6 - Normal Device Configuration (64 ms)
2.2
Back-to-Back Configuration
In Back-to-Back configuration, the two echo cancellers from the same group are positioned to cancel echo coming
from both directions in a single channel providing full-duplex 64 ms echo cancellation. See Figure 7. This
configuration uses only one timeslot on PORT1 and PORT2 and the second timeslot normally associated with ECB
contains zero code. Back-to-Back configuration allows a no-glue interface for applications where bidirectional echo
cancellation is required.
