    Warnings!

    Do not disconnect IF coaxial cable between the IDU and the ODU, in power on condition, to avoid damaging the IDU and the ODU.

    The IF cable between the IDU and the ODU is not only used for IF/control signal connection but also supply power for the ODU, connecting a test equipment directly to this terminal may damage it or touching the cable core may cause electrical shock.

    Be careful, the top surface of the IDU is hot.

    In addition to the normal Hybrid, there is a 38GHz TX Attenuator for PASOLINK. The TX Attenuator comprises directional attenuator, antenna interface, radio mounting interface and polarizer to provide attenuation only for the TX signal. The RX signal power, received by a single polarized antenna, is sent to outdoor unit (ODU) through the TX Attenuator with less than 2dB loss. On the other hand, the TX signal power transmitted from ODU is sent to antenna through the TX Attenuator with more than 30dB attenuation. The TX Attenuator is very useful in regions where EIRP regulation is strict. The NEC 38GHz TX Attenuator is suited for Andrew or RFS Antenna and NEC 38G ODU

    NEC has developed an Ortho-Mode Transducer (OMT) over the full range of microwave frequencies for waveguide interface of PASOLINK series digital microwave radio systems. The OMT comprises Ortho-Mode transducer, antenna interface and radio mounting interfaces. The two independent RF signals received by dual polarized antenna are separated and sent to two outdoor units (ODUs) through the OMT for 2+0 systems. The OMT enables dual polarization feature to double the transmission capacity for the PASOLINK system. The NEC OMT has a waveguide interface for 13-38GHz Bands, which is suited for RFS antenna

    Pole Mounting of ODU & AntennaSTEP 13 - ODU Polarisation

    A guide pin is fitted on the ODU and determines the polarisation of the unit.

    For Horizontal polarisation move the guide pin to the H position.

    Vertical polarisation is the supply default and in this case the guide pin is fitted to the plate marked with a VGuide Pin

    Plate marked with V

    Guide Pin

    This is the orientation of the ODU for vertical link polarisation. The default supply of all ODUs is vertical polarisation

    This is the orientation of the ODU for horizontal link polarisation

    Remember to install the correct Band Pass Filter before installing the ODU!

    Fit the O- ring into the antenna flange. The table below shows whether the small or large O-ring is to be used.NEC do not recommend the application of silicon grease to O-Rings

    .

    For horizontal polarisation rotate the ODU until the plate marked H is at the top, and locate the guide pin in the hole on the antenna. It is important to ensure that the holes align and that the antenna and ODU flanges mate correctly.

    For vertical polarisation, rotate the ODU until the plate marked V is at the top.

    Notes: * Do not use both small O-ring and large O-ring simultaneously. Large O-ring size is different according to frequency band, as follows:

    ANT-W/G - ODU

    Note:Only the 18-38 GHz band Andrew/RFS direct mount antenna has the option to remote mount the ODU by use of waveguide. These are therefore supplied with two O-rings; one large, one small, but only one O-ring is to be used. If the small O-ring is used for ODU direct mount installation, a gap may occur between ODU and antenna for RF interface. This may cause transmission problems

    The 13/15 GHz band antenna does not have small O-ring as this antenna does not have the waveguide-attach option.

The materials from which the hardware is manufactured must have low electrical resistance (< 0.3 ohms), and must not cause galvanic reaction. This can be prevented by using Denso tape or an inhibitor paste depending on the material used. Where stainless steel hardware is used throughout, then only an inhibitor paste is needed, otherwise both Denso, and inhibitor paste must be used.

    Locate the ODU within an area protected by lightning rod.

    To avoid surge currents caused by lightning circulating in the equipment earth system, connect the equipment earth system (frame ground) to ground of the lightning rod at ground level.

    Pole mounting of Direct Mount Hybrid, ODU and antenna for 1+1 System

    NEC has developed a Hybrid Combiner/Splitter over the full range of microwave frequencies for PASOLINK series digital microwave radio. This Hybrid comprises a directional coupler, antenna interface, radio mounting interfaces and polarizers. The RF signal power received by the single polarized antenna is equally distributed and sent to two outdoor units through the Hybrid for 1+1 protected systems.There are two types of NEC Hybrid Combiner/Splitter, one is a coaxial cable connection type for 7/8GHz Bands and the other is Waveguide connection type for 13-38GHz Bands. The NEC Hybrid is suited for Andrew or RFS Antenna. The maximum loss through the Hybrid is 20dB.

    Each field fixing kit for Pasolink contains ODU sealing rings, antenna mounting screws and antenna bracket fixing screws. Remove flange protection and install O-ring to antenna interface ports Mount the assembled unit to antenna using 4 screws. Gradually torque the antenna mounting screws to 4.0Nm to ensure good microwave contact

    ODU InstallationFix two ODUs to the hybrid with four bolts, respectively.Notes: 1. Be careful not to damage the O-ring.

    2. *Tighten to 4.0Nm torque.Remove flange protection (blue tape and/or cap) and install O-rings to ODU interface ports.Attach ODU1, orientated for correct polarisation to the hybrid ensuring that the waveguide flange lines up without damaging the O ring. Repeat for ODU2 on the other side.

    Each ODU must be earthed as explained earlier.

    ODU blanking plateThe ODU blanking plate is stored on the rear of the antenna bracket for Pasolink. It is protected with copper based anti seize paste on the screw threads. In the event of ODU failure, remove the faulty ODU leaving the ODU O-ring seal in position. Remove the blanking plate from its stored position, and screw into unused mounting holes in the recess around the relevant ODU port, to avoid RF power leaking from the hybrid and for waterproofing. Torque screws to 0.5Nm max finger tight is sufficient to ensure a waterproof seal.

    Downgrading from 1+1 system to 1+0 systemRemove ODUs and Hybrid. Attach ODU direct to dish as per previous slides or to ODU remote mounting bracket as described later. This is normally carried out after Common Unit has been set up for 1+0 system and IDU is switched off or removed. That way, the alarms are suppressed.

    Remote ODU ArrangementsAntenna Installation For Remote Mounted ODUAssemble the antenna including the mounting steel, in accordance with the manufacturers instructions.

    Attach the dish to the pole, ensuring that there will be sufficient access for maintenance and antenna alignment. Fix temporarily in position with the U-bolts at a convenient height and orientation. Ensure that the drain holes point downwards.

    Release the U-bolts sufficiently to raise the assembly to its required height and rotate the assembly to point the antenna at the remote site. If the remote site is not visible, add the current value of the difference between true and magnetic north to the bearing given in the Microwave Link Deployment Form to obtain the approximate magnetic bearing for compass alignment of the antenna. This value is to be found on maps. It does vary with time and location, so the correct map for the area, and the latest version is to be used

    Fix coaxial cable to thecable clamp with two bolts.

    Connect the cables between antenna and ODU with torque wrench respectively (pay attention to connecting torque in order not to break connector screw).

    Remote mounting of 7/8G ODU for 1+0 System:

    In the case of the 7/8GHz V4 ODU, the N-type coaxial connector is the standard method of presentation. SMA may also be an option.

    A waveguide flange option (PDR 84) will be available during a future release.

    Cabling and Connectors - IF CableA single coaxial cable links an ODU to a channel unit.

    For cable lengths up to 90m, RG223/U is typically used, with appropriate 'N' type connectors provided by the installer.

    For cable lengths greater than 90m, Belden 9913 is typically used, with appropriate 'N' type connectors provided by the installer.

    Prior to installation and with the ODU end terminated, check the cable for continuity of the screen and centre conductor. Check for short circuit between screen and centre conductor.

    Ensure that a service/drip-loop of about 1 metre is allowed for at the antenna end for maintenance or relocation purposes. The excess cabling must be secured to the pole.

    Route and secure the cable using either black UV resistant tie-wraps or studding and REM straps or equivalent approved if agreed with a third-party site owner.

    Where the cable is continuously supported by the cable tray in horizontal and vertical runs, tie in securely at maximum intervals of 1000mm. Where the cable is run on cable racking or its weight is not supported at all e.g. on walls or trays fixed vertically to walls, tie in or fix at maximum intervals of 500mm.

    Where there is insufficient space on the trays or racking, or they have not been provided, it is permissible to fix the cables to the pole or direct to a tower leg, but not to LDF Heliax feeder cables or AC power cabling.

    NOTE: Care should be taken to ensure that the coaxial cable is not damaged by strapping too tightly or strapping against sharp edges.

    Note:Tighten connectors to 196 Ncm torque. In case of employing hitless 1+1 protection, ensure the length of the two IF cables are the same (within 50m difference)

    Danger: Do not disconnect the coaxial cable before turning off the power switch on the IDU. Do not touch the IF cable jack core before turning off the power switch.

    Waterproofing ODU ConnectorWeatherproofingAll external connections, either coaxial or waveguide, must be weatherproofed, using self-amalgamating tape or an alternative.

    Start immediately next to the casing and bind the connector and cable ends to 15mm beyond the cable connector, then continue to bind back up to the start position. For an efficient seal, the self-amalgamating tape is to be pulled so as to reduce its width by 50% and overlap each turn 50%.

    When complete, it is advisable to cover the self-amalgamating tape with one layer of PVC tape also applied with a 50% overlap of each layer from the bottom up. _______________________________________________________________

    Connecting the Management PC

    Ref: Equipment Description, S04605, Section 3On initial commissioning, it is recommended that you connect the IDU to ODU after the TX/RX frequency setting has been set on the IDU. This process is most important to avoid the possibility of transmitting on the incorrect frequency.

    If powering up a 1+1 system, when neither channel is working, first set the OPR SEL switch to the desired (N0.1 or No.2) position and power on the selected MD Unit or set the OPE SEL switch to neutral (Auto) position and power on both MD units. When either No.1 or No.2 channel is working, set theOPR SEL No.1-No.2 switch on the IDU to the working channel side, then turn on the power switch of the not working channel.

    After powering up the IDU, connect the PC to the common unit, via the serial cable to the LA Port. Warning: Do not turn on the power of the IDU with a cable connected between the PC and RA PORT of the IDU.

    To access the remote end, the cable should be connected to the RA Port on the common unit (LCT Remote Access only applies if the PM card is not fitted to the IDU).

    Wait for 10 seconds or more to turn OFF the power switch of the IDU again after turning it ON. Do not repeat turning ON/OFF the power in a short time, or the IDU may fail.In a 1+1 system, before turning off the POWER switch of No.1or No. 2 channel, perform MAINT ON condition with the LCT.

    Link commissioning1. System configuration (Hot standby) When changing the system from Twin path to Hot standby, hand over the setting

    parameter of No. 1 CH to No. 2 CH. When changing the system from 1+0 to Twin path or from Hot standby to Twin path, first set the frequency of No.2 CH to 0ch and change the System configuration after 1sec. or later.

    1. Throughput (disable) [( ) denotes current state]Throughput (disable:0 / 2M:1 / 4M:2 / 8M:3 / 16M:4 / 32M:5) :Select maximum rate option from list. Enter: [0, 1, 2, 3, 4, or 5] The E1 channels are restricted depending on the throughput bit rate assignment of the

    LAN Port 1 and port 2. (see Table on next page). The throughput bit rate for the Port 2 must be set less than Port 1 or the same value with Port 1. Full bandwidth assignment of the throughput for Port 2 is not applicable.

    2. Mode (AUTONEG(AUTO-MDI/MDIX)) [( ) denotes current state]Mode AUTONEG(AUTO-MDI/MDIX) :010M-HALF(MDI) :1 / 10M-FULL(MDI) :2100M-HALF(MDI) :3 / 100M-FULL(MDI) :410M-HALF(MDIX) :5 / 10M-FULL(MDIX) :6100M-HALF(MDIX):7 / 100M-FULL(MDIX):8Select maximum rate option from list. Enter: [0, 1, 2, 3, 4, or 5] AUTONEG denotes automatic rate negotiation. The rate reverts to the slowest LAN port

    connected. HALF denotes half duplex, i.e. LAN transmission takes place one direction at a time. FULL denotes full duplex, i.e. LAN transmission in both directions at same time.

    3. Flow ctrl (on) [( ) denotes current state]Flow ctrl (off:0 / on:1) :Enter: [0, or 1] Flow control is used on LANs to minimise collisions. This is especially important where

    100M rated LANs are connected to the Radio Link LAN port as the maximum rate over the radio link is 32Mb/s (if none of the E1s are used)

    Framing (off:0 / on:1) :Enter: [0, or 1]Framing is used on LANs to control the length of frames being sent and therefore prevent a single user from occupying the bandwidth to the detriment of others. When 1 is selected, G.704 E1 formatting is applied to the LAN signal.6. Collision report (report)Collision report (report:0 / not report:1): to select whether Ethernet collisions are reported to the NMS in the form of traps.
