View Current CEC/IMC Channel Configuration
The lower list box in the Site Channel Configuration dialog box,
labeled "CEC/IMC," displays the current channel configurations stored
at the CEC/IMC for the currently selected site-type interface module.
Information within this box updates only after Send is performed from
the preceding Site 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 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.
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.
