CEC/IMC to Disk
Choose the
CEC/IMC to Disk
button to write the current CEC/IMC
configuration data to the CEC/IMC Manager hard disk. This action
will overwrite the current CEC/IMC Manager configuration for the
selected interface module. This function is useful if the CEC/IMC
Manager configuration database is lost for any reason. A difference
between CEC/IMC and CEC/IMC Manager databases will be evident
by comparing the CEC/IMC Manager and CEC/IMC list boxes in the
Site Channel Configuration dialog box. Ensure that the CEC/IMC
configuration is correct, then choose the
CEC/IMC to Disk
button to
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. The
valid range is -25.0 dBm to +12.0 dBm in 0.5 dBm increments. The
program automatically rounds-off non-0.5 dBm fractional entries to the
nearest 0.5 dBm point. 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.
