Functional Description of Register Bits
This register sets the negative ERLE sensitivity value. Raising this value decreases path change sensitivity.

Functional Description of Register Bits
This register should reflect the minimum return echo level (SIN) relative to ROUT expected in the system.
The default value of 4800
hex
= 0.5625 represents a path loss of -5 dB. This value sets the high-level double-
talk detection threshold (DTDT). The information is in 16 bit 2’s complement linear coded format presented
in two 8 bit registers for each echo canceller. The maximum value is 7FFF
hex
= 0.9999 or 0 dB.

Functional Description of Register Bits
This register sets the lower limit on SUP, which marks the region below which fast convergence always
occurs (provided a signal is present). If ERLLOW is set to the DTDT starting value (4800
hex
), the echo
canceller will remain in fast convergence mode and will not switch to slow convergence. The information is
in 16 bit 2’s complement linear coded format presented in two 8 bit registers for each echo canceller.
