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. CEC/IMC software/firmware release 5.0 (and later)
provides non-contiguous slot allocations. In this release, only
those slots actually required need be allocate. For example,
channels 1 and 4 can be allocated slots without allocating slots
to channels 2 and 3.
Notch Filter
Do not enable the notch filter on any utilized channel for a PIM,
therefore set Notch Filter to "NO" (disabled).
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 PIM Audio Board Configurations
When channel configuration of the selected PIM is complete, the
Site Channel Configuration
dialog box changes must be sent to the
CEC/IMC before the changes will take effect. This reprograms the
PIM Controller Boards. However, it is important to save the new
configuration prior to sending it to the CEC/IMC because a send will
send the last configuration that was saved to disk; saving first ensures
that the actual CEC/IMC channel configuration will be the same as the
channel configuration stored on the CEC/IMC Manager hard disk. To
save and send configurations, action is required first in the
Site Channel Configuration
dialog box and then in the
Site Channel Configuration List
dialog box.
