Five Oversampling AD/DA converters are necessary for data conversion to gain the
aspired programmability in the DSP. Generally the SLICOFI can be divided between the
AC-Loop which is handling the voice and additionally teletax and the DC-Loop for line
feeding, ringing injection and supervision.

Transmit Path
The analog input signal has to be connected to pin 21 (ITAC) by an external capacitor
(680 nF - 1
μ
F) for AC/DC separation. After passing a simple initializing prefilter (PREFI)
the voice signal is converted to a 1-bit digital data stream in the
Σ
-converter. The first
down sampling steps are done in fast running digital hardware filters. The following steps
are implemented in the micro code which has to be executed by the central Digital Signal
Processor. This DSP-machine is able to handle the workload for the DC-loop as well. At
the end the fully processed signal (flexibly programmed in many parameters) is
transferred to the IOM-2 Interface in a PCM-compressed signal representation.
Receive Path
The digital input signal is received via the IOM-2 Interface. Expansion,
PCM-lowpass-filtering, gain correction and frequency response correction are the next
