Field description:

On/off status for PSU1 located in the cabinet, and PSU2 located in the
cover if the cover is equipped.
Alarm Inputs EAL1, EAL2, EAL3, EAL4
The status for the four external alarm inputs. These alarm inputs are
intended for external alarm detectors, e.g. relays, switches, etc.
The status is shown as follows:
- With steady text OFF for neither initiated nor activated alarms (and
after Ceasing).
- With steady text ON for initiated but not activated alarms.

The EAL1 input can, alternatively, be used for a mains breakdown relay
to indicate power supply failures.
The EAL2 input can, alternatively, be used for a battery backup unit to
indicate battery backup faults.
The EAL3 input can, alternatively, be used for fiber optic alarm to
indicate link errors between the repeater and the base station, if fiber
optical link is used.
