antennas, and also setup parameters and keep optimal condition automatically; the only thing for users is
just activating this function by front panel.
Note. The users can’t adjust by manual setting when smart function is active.
Auto Level Control
The 20dB ALC is used to maintain steady output power even when the donor source signal fluctuates.
Also when the ALC is activated, the ISOLATION LED indicator would be lighted in orange, which means
the Isolation may not be enough. It also prevents UL interference and self-oscillation from insufficient
isolation between donor and server antennas.
Antenna isolation testing
P2110Aseries product also has a repeater mounted antenna isolation detection function. Equipment
installation completed boot automatically after the onset detection transceiver antenna isolation, if
transceiver antenna isolation can not meet the installation requirements, the device will automatically
reduce the gain to guarantee the equipment in normal working, not self-excitation vibration, guarantee
not to interference protection of base station, repeater itself. At the same time alarm exhibit of lanterns
bright red light alarm.
Device LED gain display panel will display device is reduced after the equipment current gain state, which
has the advantages of convenient construction, but also to protect the base station equipment, and does
not generate interference.
