Preliminary Information
Normal Configuration
For a given group (group 0 to 15), 2 PCM I/O channels are used. For example, group 1 Echo Cancellers A and
B, channels 2 and 3 are active.
Extended Delay Configuration
For a given group (group 0 to 15), only one PCM I/O channel is active (Echo Canceller A) and the other
channel carries don’t care data. For example, group 2, Echo Canceller A (Channel 4) will be active and Echo
Canceller B (Channel 5) will carry don’t care data.
Back-to-Back Configuration
For a given group (group 0 to 15), only one PCM I/O channel is active (Echo Canceller A) and the other
channel carries don’t care data. For example, group 5, Echo Canceller A (Channel 10) will be active and Echo
Canceller B (Channel 11) will carry don’t care data.
