Data Pump Miscellaneous Controls
Do not modify this location during automatic handshake or retrain.
The data pump sets this location to its default value at any reset
.
b15
TXSQLCH (Squelch Transmitter: all modes)
b14
AGCFRZ (Freeze Autogain Control: V.22/V.22bis/Bell 212A)
Set to 1 to freeze AGC adaptation.
b13
Reserved for Internal Use
Set to 0 when Dpctrl is written by the host.
b12
Reserved for Internal Use
Set to 0 when Dpctrl is written by the host.

LEQTYPE (Link Equalizer Type) Set LEQTYPE to 0 for a
fl
at
line equalizer, or LEQTYPE to 1 for a 3002 line equalizer.
b9
GTEN (Guard Tone Enable: V.22/V.22bis/Bell 212A)
This bit controls if a V.22/V.22bis/Bell 212A link has a guard
tone or not. If ia guard tone is set, the tone is transmitted
along with the carrier. This bit must not be enabled in
modes other than V.22, V.22bis, and Bell 212A. This bit
must be set prior to selecting the mode in the Con
fi
g.
register.
b8
GTSEL (Guard Tone Select: V.22/V.22bis/Bell212A)
This bit selects the guard tone frequency: 0 is 550 Hz, and
1 is 1800 Hz. This bit must be set prior to selecting the
mode in the Con
fi
g. register.
b4
EQE (EQMlev > EQMMaxThresh: V.22, V.22bis, BELL
212A)
—
The data pump sets EQE to 1 when EQMlev
exceeds the threshold set in EQMMaxThresh.
b3
EQFRZ (Freeze Equalizer: all modes)
Set to 1 to freeze adaptive equalizer (AEQ) adaptation.
AEQ coef
fi
cients are lost when a mode change (in the
Con
fi
g. register) occurs.
b2
TSPACE (Select T-spaced vs. T/2-spaced Equalizer)
This bit, when set, selects a T-spaced AEQ. When reset, it
selects a T/2 spaced AEQ. V.22/V.22bis/Bell 212A modes
always use a T/2-spaced equalizer.
