ECOTEL 3G 16.1. Revised: 1 March 2011.
The following output appears when the compression chip recognizes DTMF tones:
n14
FaxBitRate 0 Undefined or 300 bpx (T.30 con-
trol signals)
1 2400 bps
2 4800 bps
3 7200 bps
4 9600 bps
5 12000 bps
6 14400 bps
7-15 Reserved
n15
DemodulationStatus 0 EQM and Timing Offset fields are
invalid.
1 EQM and Timing Offset fields are
valid.
n16
EyeQualityMonitor (EQM) Eye Quality Monitor measure for TCF or fax im-
age. The value of 0 corresponds to the best qual-
ity of demodulation. Values greater than 100
have a negative influence on the quality of the
fax image.
n17
TimingOffsetPpm Timing Offset (ppm) recovered during demodula-
tion of TCF or fax image. The offset is a short in-
teger equal to the sum of the sampling rate error
and the sending fax baud rate offset. The value
is in integers and and may not exceed 50 ppm in
the following ranges during fax transmission
(T30TxState):
65535 – 65486 (-50ppm) 0 – 50 (+50ppm)
