To ensure safe operation of the product, a ground (earth) connection is required. For single phase AC powersource, the product must be grounded by connecting the earth wire of the power cord to the groundterminal of the AC supply. For operating this product with DC power system (such as rectifiers), the productshould not be connected to power systems that switch open the return lead because the return lead mightserve as the ground (earth) connection for the equipment.

Protective Ground Connection

The enclosure must be grounded securely by connecting a copper wire (CSA 16mm2) to the grounding

terminal on the equipment/rack, and the other end to a protective ground (i.e., building earth point). Aninternationally acceptable colour code of the ground connection wire is green/yellow.

Such a ground connection implements the Protective Ground Connection, and must be connected to theequipment at the designated ground point. In general, do not connect the supply before establishing anadequate ground (earth) connection.

Service Voltage Connection

The repeater accepts single phase 220VAC (or 110VAC) power. The recommended AC connection is ratedat AC220V (or AC110V), 10A and has three connections to include earth. The power cord has been

pre-wired to the PSU, and is identified by a label AC 220V or AC 110Vor DC +24V or DC -48V adjacentto the cable gland.

For sites with AC-to-DC power system (e.g. rectifiers), this product could be supplied to work with DCvoltages of -48V or +24V.

DC power connection from telecom rectifier is via a wire with CSA of 2.5mm2. DC voltage supply is

hard-wired to the rectifier equipment. For planning purposes, allow DC current up to 20A and 10A to bedrawn when powered with +24V and -48V respectively. The wiring to telecom rectifiers is outside the scopeof this document. Please consult and observe the installation guidelines for telecom rectifiers.

Powering option: +24V connectivity

The DC power cable for +24V is colour coded, typically as REDfor +24V or Battery and BLUEfor 0V orReturn connection.

4.8.2 RF INFORMATION

It includes: Switch (including Carrier Switch and RF Switch), Channel No., Alarm Threshold, VSWR,Temperature, Alarm Control, Pre-ATT, Post-ATT, Power, Gain, and Miscellaneous, of which RF Switch andAlarm Control are generic to the products using Comba proprietary CSP3 protocol and are described in the

OMT product manual (see Ref 0.6.2).

The following table lists the RF parameters and provides parameter description.

Node Name Description

[Switch] For the RD-8132, parameter [Switch] includes [RF Switch] and [Carrier Switch]. TheRF switch is to enable/disable the PA output. When user checks and sets non-RFparameters, such as checking physical antenna connection, switching off will disableequipment power temporarily to avoid the electro-magnetic emission from therepeater in operation. And the carrier switch provides flexibility for user to switchoff/on un-desired channel(s).

[Channel No.] This is product specific information. Includes UL/DL channel number of all available

channels.[Pre-ATT] The purpose of adjusting the Pre-ATT is to avoid BTS input power exceeds the

power range and thus to ensure call quality.

[AlarmThreshold]

Alarm Threshold includes Downlink Output Power Low Threshold, Downlink InputPower Overload Threshold, Over Temperature Alarm Threshold and DownlinkVSWR Threshold. Users can set alarm threshold according to the specific situation.If the measured value is lower than the threshold lower limit or more than thethreshold upper limit, the appropriate alarm will be generated.

[Power] Power Includes UL/DL Input/ Output power and it is equipment specific. This valueshould be within the UL/DL Input/Output Power Threshold, or else, an alarm will begenerated.A measured value of power can be read directly when equipment signals are

connected. When the measured value is lower than the minimum value, it will beshown as --, while being higher than the maximum value, it will be shown as ++.

[Gain] Gain includes Max. Gain, UL/DL Calculative Gain, UL/DL Actual Gain and is equipmentspecific.

A measured value of gain can be read directly when equipment signals areconnected. Adjustment to the UL master ATT will make change to the UL gainaccordingly, in this way, the UL and DL routes are balanced with each other and theUL output noise level is decreased. Therefore, the optimal coverage is achievable.

[VSWR] VSWR includes DL VSWR and is equipment specific. This value should be within theVSWR threshold, or else, an alarm will be generated.

[Temperature] Refer to equipment temperature and is equipment specific. This value should bewithin the Temperature Threshold, or else, an alarm will be generated.

[AlarmConfigure] Used to set alarm level and external alarm name that specifies the alarminginformation for external alarm.

4.9 COMMISSIONING PROCEDURES

System commissioning can commence after the monitoring system has completed self initialization. (i.e.,when MCU LED H3 is off and H1 begin to flash). The commissioning procedure is as follows:

Commissioning Tasks Observation

1. On-line and inquirystatus

Activate the RD-8132 Main window. Initialization will complete in about2 minutes, with MCU H3 is off and H1 flashing.

Click Connect button to enquire the repeaters status. Proceed if thereis no alarm; else check the failure and attend to the alarm.

Set device ID and alarm report mode.

2. Set On/off Status /operating band/ gain

Turn on the Power Supply switch by selecting On, and set site ID,telephone number and channel number of the repeaters operatingfrequency. Adjust the UL/DL Pre-ATT to achieve desired output power.The factory setting is 0dB, which can be set to an initial value of 30dB.

3. Set monitoring systemparameters

See RF Parameters section.

4. Set external alarmparameters

If external devices are connected to the RD-8132 for management,external alarm parameters must be enabled within the AlarmInformation area of the OMT main window.

5. Test DL input power andalign donor antenna

Observe DL input power from measured value. Align the direction ofdonor antenna until the DL input power reading is maximized.

Note: To ensure that the measured DL input power is accurate, oneshould set the DL ATT to 0 before performing the check.

6. Measuring power Check if DL power can satisfy design requirements.

7. Test DL output powerand adjust DL ATT level

Set the DL ATT to the optimal level to avoid saturating the DL PA or tosatisfy design requirement.

8. Test coverage area fieldintensity and adjust

service antenna.

Use test-handset to verify field intensity within the coverage area. Ifneeded, realign the service antenna to achieve the desired coverage.

Note: If during operation, the equipment gain could not be set tomaximum or the output power is not high enough due to insufficientdonor and service antennas isolation, then the antennas positionshould be changed to increase isolation. If the output power is too highand ALC is activated, then adjust the DL ATT to achieve optimal DLGain. It is recommended to overdrive the PA by around 3dB to turn onALC feature.

9. Verify UL gain andensure test callproduces good voicequality and there is nointerfering BTS

Adjust UL gain and perform test calls. Typically, the UL gain is setaround 10dB less than DL gain. Perform test calls in the coverage areawhile adjusting UL gain if required.

Note: If the repeater is near the BTS and the test call performance ispoor, this may be due to UL noise interference to the BTS. Users cancalculate and determine if the repeater UL noise will interfere with the

BTS. Verify again that there is no unacceptable interference to BTS.
