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. bytying it up, at outdoor work
in order to prevent door from slamming due to wind causing bodily harm or damage.
Use this unit only for the purpose specified by the manufacturer. Do not carry out any modifications or fit
any spare parts which are not sold or recommended by the manufacturer. This could cause fires, electric
shock or other injuries.
Any repeater, including this repeater, will generate radio signals and thereby give rise to electromagnetic
fields that may be hazardous to the health of any person who is extensively exposed to the signals at the
immediate proximity of the repeater and the repeater antennas.
Due to power dissipation, repeater may reach a very high temperature. Do not operate this unit on or close
to flammable materials.
Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives.
For pluggable equipment, the socket-outlet shall be installed near the equipment and shall be easily ac-
cessible.
This power of this system shall be supplied through wiring installed in a normal building. If powered directly
from the mains distribution system, it shall be used additional protection, such as overvoltage protection
device.

This function is that measuring the DL isolation value between donor antenna and service antenna during the
initialization process and setting the gain value for the repeater operation. If the measured values does not satisfy
the operating condition, the repeater is shutting down. Basically the gain value for DL/UL must be maintained un-
der [DL Isolation –15dB (±3dB)]. This process is applied to all service bands. Isolation Check is done within 30
seconds and Recheck is done within 10 seconds.
When a repeater is turned on, the system performs Isolation Check 3 times. The gain value is determined by re-
ferring to the lowest value among the three measured isolation values. If any one of these measured values does
not satisfy with operating condition (= satisfy shutting down condition), the value is excluded to the reference for
the gain value. And the repeater is shutting down.
If there occurs fluctuation in output power, more than 10 dB for 10 seconds over 5 times, the repeater performs
Isolation Recheck and set gain value properly for the last measured isolation value. After 1 hour, the repeater
performs Isolation Check one more time and set the gain value again.
Once the repeater starts to operate, the system performs the Isolation Check process one more time, once a day.
During the Isolation Recheck, the repeater is not going to shut down. If the isolation oscillation occurs while the
repeater is operating in the minimum gain value, Over-output Shutdown function performs to protect the repeater
and this time, the gain value is set to the minimum value if DL/UL gain is not under [DL Isolation -15dB (±3dB)].
Repeater Shutdown?
A repeater is shutting down when following conditions:
- DL input power is under -36dBm/Total, and measured isolation value is under 60dB.
- DL input power is over -36dBm/Total, and measured isolation value is under [DL/UL Gain + 15dB].
- Measured all 3 values satisfy above conditions.
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.

eration is described as follows.

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.
