3.1.1
The functions described in this chapter are integrated in all DuSLIC chip sets (see
Figure 3
All BORSCHT functions are integrated:
• Battery feed
• Overvoltage protection
• Ringing
• Signaling (supervision)
• Coding
• Hybrid for 2/4-wire conversion
• Testing
An important feature of the DuSLIC design is the fact that all the SLIC and codec
functions are programmable via the IOM-2 or PCM/µC-interface of the dual channel
SLICOFI-2x device:
• DC (battery) feed characteristics
• AC impedance matching
• Transmit gain
• Receive gain
• Hybrid balance
• Frequency response in transmit and receive direction
• Ring frequency and amplitude
• Hook thresholds
• TTX modes
Because signal processing within the SLICOFI-2x is completely digital, it is possible to
adapt to the requirements listed above by simply updating the coefficients that control
DSP processing of all data. This means, for example, that changing impedance
matching or hybrid balance requires no hardware modifications. A single hardware is
now capable of meeting the requirements for different markets. The digital nature of the
filters and gain stages also assures high reliability, no drifts (over temperature or time)
and minimal variations between different lines.
