NAME
CONDITION
DESCRIPTION
0
The adaptive equalizer is in its initialized state.
D0
Equalizer
Enable
1
The adaptive equalizer is enabled. This bit is used in
handshakes to control when the equalizer should
calculate its coefficients.
0
The adaptive equalizer is active.
D1
Train Inhibit
1
0
The adaptive equalizer coefficients are frozen.
The DSP is inactive and all variables are initialized.
D2
RESET DSP
1
The DSP is running based on the mode set by other
control bits
0
The receiver and transmitter are using the same decision
plane (based on the Modulator Control Mode).
D3
16 Way
1
The receiver, independent of the transmitter, is forced
into a 16 point decision plane. Used for QAM
handshaking.
0
The transmitter when placed in alternating Mark/Space
mode transmits 0101 . . . . scrambled or not dependent
on the bypass scrambler bit and Modulation mode.
D4
Transmit
S1
1
When this bit is 1 and only when the transmitter is placed
in alternating Mark/Space mode by CR1 bits D7, D6, an
unscrambled repetitive double dibit pattern of 00 and 11
at 1200 bit/s (S1) is sent.
0
The DSP is setup to do demodulation and pattern
detection based on the Various mode bits. Both answer
tones are detected in Demod Mode concurrently; TR D0
is ignored.
D5
Call Init
1
The
unscrambled mark, and 2100 Hz and 2225 Hz answer
tones.
