3.3.3
The IEC-4-AFE-X Version 3.2 implements a digital low-pass filter. The filter
characteristic is optimized for high stop-band attenuation with a very steep transition
from pass-band to stop-band. Due to this filter characteristic and in connection with
external circuitry as specified in
AFE-X Version 3.2 PSD at the lineport of the starpoint hybrid meets the ADSL-friendly
ISDN-PSD-mask requirements according to
Therefore, ADSL service based on GEMINAX MAX chip set may be operated on the
same pair as ISDN service based on IEC-4-AFE-X Version 3.2 / DFE-T V2.2 / DFE-Q
V2.2 without a discrete, passive splitter device.
3.3.4
The output pulse is transmitted by a special DAC and a linedriver with high linearity.
