General Description
1 General Description
The Signal Processing Subscriber Line Interface Codec Filter SLICOFI
(PEB 3065/PEF 3065) is a logic continuation of the well established family of the
SIEMENS PCM-Codec-Filter-IC’s with the vertical integration of all DC-feeding,
Supervision and Meterpulse Injection features on chip as well. Fabricated in a standard
1 µm BiCMOS technology the SLICOFI is tailored for very flexible solutions in digital
communication systems.
For the first time the SLICOFI uses the benefits of a DSP not only for the voice channel
but even for line feeding and supervision which leads to a very high flexibility without the
need for external components.
Based on an advanced digital filter concept, the PEB 3065/PEF 3065 provides excellent
transmission performance. The new filter concept (second generation in
SIEMENS-Codec-family) leads to a maximum of independence between the different
filter blocks. Each filter block can be seen as a one to one representative of the
corresponding network element. Together with the software package SLICOS, filter
optimizing to different applications can be done in a clear and straight forward procedure.
The AC frequency behavior is mainly determined by the digital filters. Using the new
oversampling 1 bit-AD/DA converter, linearity is only limited by second order parasitic
effects.
The new - digital - solution of line feeding offers free programmability of feeding current
and voltage as well as very fast settling of the dc-operating point after transitions.
A 0.3 Hz lowpass filter in the DC-loop is mainly responsible for the system stability.
Additionally teletax generation and filtering is implemented as well as free programmable
(balanced) ring generation with zero-crossing injection. Offhook detection with
programmable thresholds is possible in all operating modes. To reduce overall power
consumption of the line card, the SLICOFI provides a special mode called Power Denial
where Offhook is done via 2 high voltage inputs (VLINE1 and VLINE2) directly connected to
the line if the HV-SLIC is switched off.
