F.2.3.3 Pilot test carrier
The pilot test carrier is related to each bank first channel at current first
channel frequency.
The test carrier may be ON (transmitting) when the pilot test carrier setting is
enabled and the first filter in each bank has checked Tx Enable.
F.2.3.4 MCPA Control:
For the “Output MCPA Mute” and “Reset Reflected Power Alarm Reset”
commands, the user can set the preferred control method by choosing
Software or Hardware in the “Control by” field.
a. If the user chooses hardware control, the controller will respond to the
opto-isolated inputs located in the ECM I/O DB25 Connector and the
software commands for these two parameters will have no effect.
The Reset Reflected Power Alarm command mapped to ECM I/O DB25
Connector can be controlled through pins 3 and 4 for both Service Side
(DL Tx) and Donor Base (UL Tx) outputs.
The Power Amplifier Mute command mapped to ECM I/O DB25
Connector can be controlled through pins 1 and 2 for both Service Side
(DL Tx) and Donor Base (UL Tx) outputs.
When “Control by Hardware” is selected the UL and DL MCPAs are
automatically un-muted unless the corresponding opto-isolated input is
energized.
b. On the other hand, if the user chooses software control, the controller
will respond to these software commands instead of to the opto-isolated
inputs.
