Appendix C List of Parameters Installation and Operation Manual
C-8 Configure Transmission Parameters ASMi-52CD Ver. 1.0
Parameter Type Use Value Indication
Integer
between -10
and 10
Selected current margin value
CURRENT MARGIN Write Selecting the minimum
desired target margin for
the local line conditions
during the startup
sequence.
Available only if the rate
adaptation is enabled (see
line probing configuration
below)
Disable Disable current margin.
Allows the use of all line rates,
regardless of line condition
Symmetric Supported in both Annex A and
Annex B modes.
ASYM PSD Write Defining the amount of
power applied to the
information signal in order
to achieve a satisfactory
level of signal strength at
the receiving end of the
circuit
Asymmetric • Annex A at 768 kbps
• Annex B at 2048 kbps.
Fixed No line probing
ASMi-52CD/4 modems support
fixed line probing only.
LINE PROB Write Indicating whether the
modem should perform a
line probe in order to find
the best possible rate of
transmission
Adaptive Force a line probing
ASMi-52CD/2 modems support
adaptive mode only.
Master Selected modem operated with
the clock set by the Clock
Source field of the Modem
Setup menu (see
Figure C-2
)

ATTENUATION
THRESHOLD
Write Setting the acceptable
difference (in dB) between
the power transmitted
from the ASMi-52CD
modem and the power
received by the remote
modem.
0 dB to 127
dB
Minor alarm is generated (LOOP
ATTN. OVER LINE A/B), if
selected loop attenuation
threshold value is exceeded
SNR MARGIN
THRESHOLD
Write Setting the signal-to-noise
ratio threshold.
0 dB to 15 dB Minor alarm is generated (SNR
MARGIN OVER LINE A/B), if the
selected signal-to-noise ratio
threshold is exceeded
