The figures in this specification are based on the subscriber-line board requirements.
The proper adjustment of the programmable filters (transhybrid balancing, impedance
matching, frequency-response correction) requires a complete knowledge of the
SICOFI-2/4 TE’s analog environment. Unless otherwise stated, the transmission
characteristics are guaranteed within the test conditions.

A-Law
A 0 dBm0 signal is equivalent to 1.095 Vrms. A + 3.14 dBm0 signal is equivalent to
1.57 Vrms which corresponds to the overload point of 2.223 V.
When the gain in the receive path is set at 0 dB, an 1014 Hz PCM sinewave input with
a level 0 dBm0 will correspond to a voltage of 1.095 Vrms at the analog output.
When the gain in the transmit path is set at 0 dB, an 1014 Hz sine wave signal with a
voltage of 1.095Vrms A-Law will correspond to a level of 0 dBm0 at the PCM output.
In transmit direction for -law an additional gain of 1.94 dB is implemented automatically,
in the companding block (CMP). This additional gain has to be considered at all gain
calculations, and reduces possible AX-gain from 8 dB (with A-Law) to 6 dB (with -Law)
A 0 dBm0
1.57 Vrms which corresponds to the overload point of 2.223 V.
When the gain in the receive path is set at 0 dB, an 1014 Hz PCM sinewave input with
a level 0 dBm0 will correspond to a voltage of 1.0906 Vrms at the analog output.
When the gain in the transmit path is set at 0 dB, an 1014 Hz sine wave signal with a
voltage of 1.0906 Vrms will correspond to a level of 1.94 dBm0 at the PCM output.
