LBI-38938 contains a line level adjustment overview section which
contains general information and general recommendations for both
input and output level settings.
Bus/Slot Equipped
Only one TDM bus time slot is normally required for each console
since there is only one transmit channel per console. However, if the
Call Director option will be used with the console two slots are required
(see Note below).
In earlier CEC/IMC firmware/software releases, slot
allocations could only be made contiguously starting with
channel one (1). In some systems this produced slot allocation
inefficiencies—some slots had to be allocated but were never
used. For example a CIM supporting a Call Director had to be
allocated four (4) slots so CIM channel 4 could be used for
Call Director transmit audio. In this release, only those slots
actually required need be allocated; therefore, a CIM
supporting a Call Director requires only two (2) slots—one for
channel 1 and one for channel 4.
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."
Save and Send CIM Channel Configurations
When channel configuration of the selected console is complete, the
Console Channel Configuration dialog box changes must be sent to
the CEC/IMC before the changes will take effect. This reprograms the
CIM Controller Boards. However, it is important to save the new
