at the CEC/IMC for the currently selected console interface module.
Information within this box updates only after
Send is performed from
the preceding Console Channel Configuration List dialog box.
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 console. 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
Console 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 console.
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
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 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 when the ALC
text box is "NO."
