DuSLIC
Functional Description
Preliminary
The characteristics for the two voice channels within SLICOFI-2x can be programmed
independently of each other. The DuSLICOS software is provided to automate
calculation of coefficients to match different requirements. DuSLICOS also verifies the
calculated coefficients.
3.1.2
Additional Functions available for DuSLIC-E/-E2/-P Chip Sets
The following line circuit functions are integrated only in the DuSLIC-E/-E2/-P chip sets
(see
Figure
8):
• Teletax metering
For pulse metering, a 12/16 kHz sinusoidal metering burst has to be transmitted. The
DuSLIC chip set generates the metering signal internally and has an integrated notch
filter.
• DTMF
DuSLIC has an integrated DTMF generator comprising two tone generators and a DTMF
decoder. The decoder is able to monitor the transmit or receive path for valid tone pairs
and outputs the corresponding digital code for each DTMF tone pair.
• Caller ID Frequency Shift Keying (FSK) Modulator
DuSLIC has an integrated FSK modulator capable of sending Caller ID information. The
Caller ID modulator complies with all requirements of ITU-T recommendation V.23 and
Bell 202.
• LEC (Line Echo Cancellation)
DuSLIC contains an adaptive line echo cancellation unit for the cancellation of near end
echos (up to 8 ms cancelable echo delay time).
• UTD (Universal Tone Detection)
DuSLIC has an integrated Universal Tone Detection unit to detect special tones in the
receive or transmit path (e.g. fax or modem tones).
