The Signal Processing Subscriber Line Interface Codec Filter SLICOFI PEB 3065/PEF 3065 (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 m BiCMOS PEB 3065/PEF 3065 technology the SLICOFI is tailored for very flexible solutions in digital communication systems.
For the first time the SLICOFI PEB 3065/PEF 3065 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 of PEB 3065/PEF 3065 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 PEB 3065/PEF 3065 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 of PEB 3065/PEF 3065 is possible in all operating modes. To reduce overall power consumption of the line card, the SLICOFI PEB 3065/PEF 3065 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.
