the modem Level output transmissions. The closer
the transmit level is to zero the greater the level
(strength) of the output signal. This parameter
should only be changed under the direction of
service personnel. The default condition for the
transmit level is 0 dbm. The transmit level settings
are as follows:

T Level
This command selects the type of adaptive equalizer
used by the receiver. In most cases, a two taps per
baud spre`ad over 16 bits gives the best
performance because of the increased sample rate
and the resulting reduction of alias errors. In cases
where the line has ringing or echoing, a one tap per
baud spread over 32 bits may be necessary.
$T1:
T/2 with one tap per baud
$T2:
T/2 with two taps per baud (default)
$W
Write Configurations to Modem
The Write Configurations to Modem command ($W)
incorporates any updated internal modem

on a temporary basis. This permits you to try various
configurations before storing them in memory by
executing the &W command.
