Preliminary
The UTDR-OK respectively UTDX-OK bit (register INTREG3) will be set if both of the
following conditions hold for a time span of at least RTIME without breaks longer than
RBRKTime occurring:
1. The in-band signal exceeds a programmable level Lev
2. The difference of the in-band and the out-of-band signal levels exceeds Delta
The UTDR-OK respectively UTDX-OK bit will be reset if at least one of these conditions
is violated for a timespan of at least ETime during which the violation does not cease for
at least EBRKTime.
The times ETIME and EBRKTime help to reduce the effects of sporadic dropouts.
If the bandwidth parameter is programmed to a negative value, the UTD unit can be used
for the detection of silence intervals in the whole frequency range.
The DuSLIC UTD unit is compatible with ITU-T G.164.
The UTD is resistant to a modulation with 15 Hz sinusoidal signals and a phase reversal
but is not able to detect the 15 Hz modulation and the phase reversal.

Operating System
The maximum capability of the EDSP is 32 MIPS.
Example:
• All devices enabled and LEC Length = 8 ms (LEN = 64):
• All devices enabled and LEC Length = 4 ms (LEN = 32):
• 4 x UTD, 2 x DTMF Receiver and 2 x LEC (8 ms) enabled:
