The EAL4 input can, alternatively, be used for a repeater door switch to
indicate open repeater cover.
External alarms are assigned alarm levels in the Alarm Configuration
window (see the Alarm Configuration section in Chapter 11).
The external alarm inputs EAL1 - EAL4 are further described in the
Alarm Overview section in Chapter 11, Alarms and Events, and in the
P33 Alarm Port section in Chapter 3, OMT32 Installation.
Measured Values Input LNA Atten. Control
Gain control voltages attached to the uplink and downlink LNA antenna
input low noise amplifiers.
Low voltage (<0.5VDC) means maximum LNA gain.
Voltage range: 0V - 5VDC.
CU battery
The CU board battery voltage used by the calendar clock and event log
memory.
The battery voltage should be 2.7V - 3.5V.
Temp. now
Current CU board temperature in degrees Celsius.
Temp. max.
The highest measured CU board temperature since the last alarm reset.
The temperature is shown in degrees Celsius.
This temperature is reset to the currently measured temperature when an
alarm reset is performed. Alarm reset is described in Chapter 11, Alarms
and Events.
Temp. min.
The same as Temp. max. but this is the lowest measured CU board
temperature.
REFO drift
Shows a supervision count value for the reference oscillator (REFO)
frequency counter.
The count value shall be within ±10.
