In the high speed transmit mode, the modem sets the SCR1S status bit to indicate that the modem is
sending the scrambled ones sequence. In the high speed receive mode, the modem sets the SCR1S status
bit to indicate that the modem is receiving the scrambled ones sequence. In the receive mode, SCR1S is
reset to indicate that the modem is not receiving the scrambled ones sequence.
The KS16114 supports V.17 and V.27ter short train while the KS16112 supports V.27ter short train.
To utilize these short train modes, the receiver must first be trained using a long training sequence at the
same speed as the subsequent short training sequence. After the long training sequence has been success -
fully received, the host may configure the modem for short train mode by setting SHRTN. At this time the
host must also set the SAVEQ bit to preserve the equalizer tap coefficients obtained during the long train.

When in the high speed transmit mode, the modem sets the SILIDL status bit to indicate that the modem
is transmitting silence. In the high speed receive mode, the modem sets the SILIDL status bit to indicate
that the modem is in the idle state waiting for energy to be received.
The TD1 bit is set when the modem detects energy above the turn - on threshold of tone detector No 1.
As the default, tone detector No.1 is programmed to detect energy in the 2100 Hz
±
25 Hz frequency range.
All three tone detectors ( TD1, TD2 and TD3 ) have host programmable filter coefficients.
Tone detector No. 1 is operational in FSK, FSK and DTMF receiver and Tone configurations and whenever
the modem is not transmitting.
The TD2 bit is set when the modem detects energy above the turn on threshold of tone detector No 2.
As the default, tone detector No. 2 is programmed to detect energy in the 1100 Hz
±
30 Hz frequency range.
All three tone detectors ( TD1, TD2 and TD3 ) have host programmable filter coefficients.
Tone detector No. 2 is operational in FSK, FSK and DTMF receiver and Tone configurations and whenever
the modem is not transmitting.
