Functional Description of Register Bits
0
Must be set to zero.
These three bits (SD2,SD1,SD0) control how long the echo canceller remains in a fast
convergence state following a path change, Reset or Bypass operation. A value of zero will keep
the echo canceller in fast convergence indefinitely.
Must be set to zero.
Slow convergence mode speed adjustment.(Bits Slow2, Slow1,Slow0)
For Slow = 1, 2,..., 7, slow convergence speed is reduced by a factor of 2
Slow
as compared to
normal adaptation.
For Slow = 0, no adaptation occurs during slow convergence.

Functional Description of Register Bits
This register is used to scale the comfort noise up or down. Larger values will increase the relative level of
comfort noise. The default value of 16
hex
will provide G.168 compliance with the Advanced NLP. A value of
74
hex
is recommended if the original NLP is used.

Functional Description of Register Bits
Reserved bits. Must be set to 4

for normal operation.
Noise level estimator ramping rate. When InjCtrl = 1, a lower value will give faster ramping.
When InjCtrl = 0, a higher value will give faster ramping. The default value of 5
hex
will provide
G.168 compliance with InjCtrl = 1. A value of C
hex
is recommended if InjCtrl = 0.
