Chapter 5 - Commands

The Receive Level settings are as follows:

$RL0: -43 dbm (default)

$RL1: -26 dbm

$TL0-7 Transmit

The Transmit Level Command selects the level of

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:

$TL0: 0 dbm (default)

$TL1: -2 dbm

$TL2: -4 dbm

$TL3: -6 dbm

$TL4: -8 dbm

$TL5: -10 dbm

$TL6: -12 dbm

$TL7: -14 dbm

$T1-2 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

parameters into the operation of the internal modem

on a temporary basis. This permits you to try various

configurations before storing them in memory by

executing the &W command.
