1. GENERALThis section provides information on the NEC New Pasolink 13/15/18/23/26/38 GHz 4/8/17/34 MBpoint-to-point digital radio system. The ( )GHz ( )MB digital microwave radio system is configured in1+0 system. Included herein are system configuration, system performance, mechanical configuration,interface, presetting switches, initial lineup and maintenance.

2. SYSTEM CONFIGURATIONThis system consists of TRP-[ ]G-[ ] Transmitter-Receiver (Outdoor Unit (ODU)) and MDP-[ ]MB-[ ]Modulator-Demodulator (Indoor Unit (IDU)) (see Fig. 2-1).

The [ ]GHz 4 MB (2 MB × 2) digital radio system is used to communicate two data streams at 2.048Mbps (equivalent to 30 voice channels) between two stations.

The [ ]GHz 8 MB digital radio system is used to communicate one data stream at 8.448 Mbps(equivalent to 120 voice channels) or four data streams at 2.048 Mbps (equivalent to 30 voice channels)between two stations.

The [ ]GHz 17 MB (2 MB × 8) digital radio system is used to communicate eight data streams at 2.048Mbps (equivalent to 30 voice channels) between two stations.

The [ ]GHz 34 MB digital radio system is used to communicate one data stream at 34.368 Mbps(equivalent to 480 voice channels) or sixteen (16) data streams at 2.048 Mbps (equivalent to 30 voicechannels) between two stations.

The system block diagrams of 2 MB × 2, 2 MB × 4, 2 MB × 8 and 2 MB × 16 systems are shown in Fig.2-2, and that of 8 MB × 1 and 34 MB × 1 systems are shown in Fig. 2-3.

METER:Indicates receiving RF level voltage.

OW indicator:Lights when OW communication is performed (The OW ON-OFF switch is set to ON). When the OW indicator is not lit even though OW switch is set to ON, replace the battery (6F22(UB)/9V) since the battery becomes weak.

OW ON-OFF switch:Enables to transmission OW signal between IDU and ODU. When the OW communication is performed, OW ON-OFF switch is set to ON.

VOL control:Enables to adjust receive OW voice level.

RX LEV/OW IN jack:Supplied monitoring RX LEV voltage and OW signal from the ODU.

HEADSET jack:Permits communication between IDU and ODU when orderwire headset is connected.

8. MAINTENANCEThis section provides instructions for periodic maintenance and corrective maintenance of the IDU.Included is information on precautions, test equipment and accessories, periodic maintenance andcorrective maintenance.

8.1 Precautions

The following precautions must be carefully observed during maintenance.

Danger: The −43 V DC power is superimposed on the center conductor of the coaxial cablebetween the IDU and ODU. Connecting a measurement set may damage that setand touching the coaxial cable core may cause electrical shock. So, turn off powerswitch on the IDU before connecting or disconnecting the coaxial cable betweenthe IDU and ODU.

Caution: To protect the internal circuits against electrostatic discharge, engineers arerequested to wear the wrist band and connect it to the frame ground forElectrostatic Protection (ESP) before detaching the top cover (see Fig. 8-1).

Fig. 8-1 Location of ESP Button

(a) Before beginning maintenance, notify the opposite station that maintenance is about to begin.

(b) After equipment start-up, allow the equipment to warm up for at least 30 minutes.

(c) After completing the maintenance operation, restore all connections to normal.

(d) During maintenance, the IDU is set to maintenance condition using a PC as follows:

Caution: If Login is not posisible, check if settings of the communication format are proper.

8.4 Corrective Maintenance

In this paragraph, corrective maintenance in the field is described. Corrective maintenance in the fieldcovers fault isolation, replacement and alignment. The fault isolation procedures describes isolatingequipment-level faults without checking equipment. Therefore, if a ODU is faulty, it should bereplaced with a spare and aligned.

During corrective maintenance, carefully observe the precautions given in paragraph 8.1 untilalignment is completed.

8.4.1 Fault Isolation

Alarm conditions are identified through:

• Red alarm LED indication on the IDU or

• Notification from external equipment

During alarm conditions, red alarm LEDs on the IDU are lit except when there is a power supplyfailure. Faults can be isolated using the LED indications. Table 8-4 provides information for isolatingfaults at a station.

• Screwdriver

(b) Procedure

Step Procedure

Removing

1 Turn off the POWER switch on the front panel of the IDU (see Fig. 8-4),

2 Loosen tightening rings of the IF IN/OUT (N) on the ODU by turning them counter-clockwise,

3 For waveguide connector type of ODU, to remove the waveguide from the RF IN/OUT,remove the four waveguide fixing screws using a screwdriver,

Note: Be careful not to damage the O-ring between the waveguide and ODU,

4 Loosen four screws (M6) on the ODU (see Fig. 8-5),

5 Remove the ODU from mounting bracket,

(B) IDU

The Manufacturer does not recommend replacement of modules within IDU. If a fault is identified withthe IDU, the complete unit should be replaced with a spare. The faulty unit is to be returned to thefactory for repair.

When replacing with a new unit, the start up procedure should be followed. Refer to para. 7.1.1.

8.4.4 Alignment

After replacing the ODU or IDU with spares, the ODU or IDU must be aligned as follows.

Caution: After replacing any unit and/or module with a spare, allow equipment to warm upfor at least 30 minutes before alignment.

3.2 ODU Mounting on Andrew Antenna

Procedure for mounting methot is as follows:

Factory setting of antenna is V polarization. When the H polarization is required, steps 1 to 5 ofprocedure is performed.

Step 1. Remove the antenna radome.

LARGE O-RING

Note: In 18-38GHz band 2 O-rings are attached in Andrew direct mount antenna kit, large oneis used for ODU mounting and small one is used for only waveguide connection. 13 and15GHz band antenna doesn’t have small O-ring. (Small O-ring isn’t used for Andrewdirect mount antenna.)If the small O-ring is used for ODU direct mount installation, a gap occurs betweenODU and antenna for RF interface, because ODU has a small tab at RF interface and itinterfere to the small O-ring. Therefore it may happen transmit or receive level down.

SMALL O-RING(ONLY FOR WAVEGUIDE CONNECTION)

ANTENNA INTERFACE PORT


2-11

Step 3. Hold the antenna with your hand to rotate it by90 degrees.

Step 4. Check the aperture part of the connection unit isrotated by 90 degrees, the fix it with screws thatwere loosened in step 2.

Step 5. Fix the radome that was removed in step 1.

Step 2. To rotate the antenna connection unit, keep theantenna stand horizontally and loosen screwswith Allen wrench.

Note: Connection unit and radiator are integrated.Do not keep the antenna aperture downloadfor working, or the radiator may drop or getdamaged.

2-12

Step 8. Mount the mount pivot plate with v-clamp to the pole.

Step 9. Tight M10 hex head screw with wrench to fix the plate.

Step 10. Mount the mounting bracket to the pivot plate mounted in step 8.

Step 11. Adjust the elevation and tighten M10 hex head screw with wrench to fix the mountingbracket.

Step 6. Mount the azimuth adjustment clamp and v-clamp to the pole.

Step 7. Tighten M10 hex head screw with wrench to fix the clamps.

ROI-S03423

2-13

Step 12. Mount the antenna to the mounting bracket.

Step 13. Tighten M10 hex head screw with wrench to fix the antenna.

Step 14. When vertical polarization is required, rotate the ODU so as to go up the plate marked V.

Step 15. When horizontal polarization is required, remove the guide pin fixed on the plate markedwith V.

Step 16. Insert the guide pin removed in step 15 behind of the plate marked H.

Step 17. Rotate the ODU so as to go up the plate marked H.
