LBI-39224
3-52
If Automatic Level Control (ALC) is disabled for the selected
channel, subtract 1.5 dBm from the required Input Signal
Level setting. For example, if the required input signal level is
-10 dBm, enter -11.5 dBm. ALC is disabled by setting the
ALC text box to "NO."
LBI-38938 contains a line level adjustment overview section which
contains general information and general recommendations for both
input and output level settings.
Output Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) sent out by the selected channel's line output. The
setting specifies the voice peak (test tone) level sent out by the channel.
Valid range is -25.0 dBm to 13.0 dBm, in 0.5 dBm increments. Select
the required value from the drop-down list box. Output Signal Level
default = 0 dBm.
Bus/Slot Equipped
All utilized channels within an interface module must be allocated a
time slot on the CEC/IMC TDM network. Allocate a time slot to the
selected channel by setting Bus/Slot Equipped to "YES." A channel
will not route audio correctly if is not allocated a time slot. Set all
unused channels to "NO" (default setting).
Channel Equipped
This parameter is unique to NIMs, and must be enabled for each
installed distributed multisite audio channel. Enter "YES" in the text
box to enable those channels, enter "NO" for all unused channels.
ALC
DO NOT enable ALC for any channel if the respective Audio
Board part number is 19D903302P1 (any revision).
Automatic Level Control (ALC) provides compensation for signal level
variances in a channel line input signal. As required, enable ALC for
the selected channel by entering "YES" in the ALC text box or disable
it by entering "NO."
