General
“Only qualified personnel are allowed to handle this unit. Read carefully and understand all the warning
labels attached in this user manual”. Any personnel involved in installation, operation or service of the
SOLiD repeaters must understand and comply the following:
Understand all general and regional installation and safety regulations relating to work on high voltage
installations, as well as regulations covering correct use of tools and personal protective equipment.
The power supply unit in repeaters contains dangerous voltage level, which can cause electric shock.
Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when
servicing repeaters.
The repeater cover should be (door) securely fastened in open position, e.g. by tying itup, at outdoor work
in order to prevent door from slamming due to wind causing bodily harm or damage.

The following block diagram describes the operation principle, how the repeater works (e.g. 1.8GHz frequency
range (b3)).
Isolation Check and Gain Limitation
The repeater often checks DL isolation between a donor antenna and a service antenna while servicing at work-
ing frequency. Basically the gain value for DL/UL must be maintained under [DL Isolation –15dB (±3dB)]. To
calculate the isolation value, the correlation value of input signal and that of the feedback signal are used.
If isolation value is measured [Gain + 7 dB] at 1.8 GHz or [Gain + 12 dB] at 3.5 GHz more than 30 seconds, the
repeater reports oscillation alarm and shuts down 5 seconds later. And the repeater maintains its shutting down
state until the power turned off and on or performs CPU reset.
Even though the oscillation state is maintained for more than 30 seconds, the oscillation may occur bigger be-
cause the isolation is getting worse. In this case, the repeater performs Over-output Shutdown.
Automatic Gain Control (AGC)
This function is that controlling gain value to maintain DL output power is [user setting value ±2 dBm] when

each service band’s DL input power is within rated range. The UL Gain must be maintained [DL Gain ±2 dB]. If
the Isolation ATT value is set due to Isolation Check, the repeater can control AGC ATT within [30dB - Isolation
ATT]. The DL In/Output and DL/UL Gain value for AGC operation is described as follows.

ALC for UL over-output
Basically, each service band’s UL Gain value is controlled by AGC. The ALC maintains UL output level is under
[Rated power ±2dB]. The attenuator used for ALC function for UL over-output is same hardware as the one used
for the ALC function for UL over-input. The attenuator for the AGC uses a different hardware from the ALC one.
Shutdown for UL/DL over-output
This function is that automatically shutting down the service band when the DL/UL output of each service band is
over the rated. During DL Shutdown, UL Shutdown is also proceed at the same time and this is vice versa. The
operating level is [(Rated output level +2dB) ±2dB] and working algorithm is described as follows.
In ‘Check’ state, if the power level is back to normal from over-output level, the algorithm is reset. If ‘Complete
Shutdown’ occurs, a repeater is kept shut-down state, until performing Power on / Reset / Isolation Re-check.
Dying Gasp
This function is to report the alarm "Failure of the DC power supply" to the NMS using the standby power from a
connected capacitor if the DC power supply of the repeater is interrupted.
