The quality of Transhybrid-Balancing is very sensitive to deviations in gain, group delay,
and deviations inherent to the A/D- and D/A-converters, as well as to all external
components used on a linecard (SLIC, OP’s etc.).

by-passed. The IM-filter is disabled, (H(IM)=0). The balancing filter TH is enabled with
optimized coefficients for this configuration (
A 0 dBm0 sine wave signal with a frequency in the range of 300 Hz to 3400 Hz is applied
to the digital input. The signal levels of the resulting echo at the digital output will stay
below the values shown in Table 20.
