restore the CEC/IMC Manager configuration database for the selected
interface module.
Channel Selection
Select a channel (1 thru 32) for configuration from the CEC/IMC
Manager channel list box, only one channel may be selected at a time.
The selected channel and its configuration data will be displayed in the
edit fields above the CEC/IMC Manager list box.
Input Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) applied to the selected channel's line input. Enter
(type) the required value in the text box. The setting should be equal to
the voice peak (test tone) level applied to the channel's line input.
Voice peak levels are +10 dBm greater than average voice levels.
Valid range is -25.0 dBm to 12.0 dBm, adjustable in 0.5 dBm
increments. The program automatically rounds-off non-0.5 dBm
fractional entries to the nearest 0.5 dBm. Input Signal Level default =
0 dBm.
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.
The 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.
