1. GENERAL
This section provides information on the NEC PASOLINK 7-38 GHz 2/4/8/16 x 2 MB and/or 2 x 10/100Base-T(X) LAN signals transmissiondigital microwave radio system. Included herein are notice for systemoperation, system configuration, system performance, RF channelassignment, and alarm and control.
1.1 Notice (Operation)
1. To prevent accidental IDU power switch lever movement,the power switch lever is locked. When set the powerswitch to on/off, it must be pulled out power switch leverknob to unlock the switch lever.
2. After turning ON the equipment, wait at least 10 secondsor more before turning it OFF again. Repeatedly turningthe power ON and OFF within a short interval may causethe IDU to fail.
3. Do not disconnect I/F cable between the IDU and theODU in power ON condition, to avoid damaging the IDUand ODU. Do not connect/disconnect the I/F cable withIDU power ON, turn IDU power OFF before connecting/disconnecting the I/F cable.
4. Persons performing servicing must take necessary steps toavoid electro-static discharge which may damage themodules on the IDU or cause error. Wear a conductivewrist strap connected to the frame ground (FG) terminalon the front of the equipment shelf. This will minimizestatic build-up during servicing.
5. In back -to-back connection, the interface conditions ofthe PM CARD must be matched between two IDUs. Then,check the setting of the interface if it is RS-485 or RS-232C before connecting the cable.
6. Do not turn on the power of the IDU leaving cableconnection between the PC and RA PORT of the IDU.
7. When the radio frequency is changed in maintenance, first,set frequency in the opposite station. If you set radiofrequency in the local station at first, you can not changeradio frequency of the opposite station using PC menu atthe local station. Because the opposite station can notreceive the control signal to be set radio frequency.

8. The equipment is applied only SEL V (Safety Extra-LowVoltage) power supply, do not apply a voltage that variessharply. This may cause abnormal operation.
9. In 1+1 system, when neither No.1 nor No.2 channel isworking, first set the OPE SEL switch to the desired(No.1 or No.2) position and power on the selected MDUnit or set the OPE SEL switch to neutral (Auto) positionand power on both MD units.
In 1+1 system, when either No.1 or No.2 channel isworking, set the OPR SEL No.1-No.2 switch on the IDUto the working channel side, then, turn on the powerswitch of the not working channel.
10. In 1+1 system, when demounting the ODU from theantenna direct mounting HYB, mount the attachedSHORT PLATE to the demounted port of the HYB toavoid RF power leaking from the hybrid and forwaterproofing.
11. In 1+1 system, to avoid occurrence of bit errors due tomicrophonic properties, when installing the standby ODUon to the antenna direct mounting HYB, protect theworking ODU from mechanical knocks.
12. In 1+1 system, when the SW UNIT is replaced with aspare, the service is interrupted.
13. Before the start of maintenance, including operation ofthe OPR SEL SW on the front panel of the equipment,select the equipment to maintenance mode using the LCT.
After all operation for maintenance have been completed,perform MAINT OFF setting.
14. Before connecting the I/F cable between the IDU andODU, using circuit tester, check that the resistance of theI/F cable between center conductor and insulation ismore than 100 MΩ.
15. When the LAN INTFC is used, the domestic is anenvironment where the use of broadcast radio andtelevision receivers may be expected within a distance of10 m of the apparatus concerned.
16. 16x2MB bit rate is not supported on MDP-17MB-3/4A.

17. It is recommended that you connect the IDU to ODUafter the TX/RX frequency and TX power control settinghas been set on the IDU.
This process is most important for the following ODUs thatmay be emitted TX power if you set the channel number to"0ch" which is not defined (excepting 13/26/38 GHz band)by the Radio Frequency Assignment.
Code No. of Corresponding ODU:H0738 (7 GHz), H0739 (8 GHz), H0330 (13 GHz),H0331 (15GHz), H0332 (18GHz), H0333 (23 GHz), H0334 (26 GHz), H0335 (38 GHz)
18. Note that the setting of the DEM Invert is important.The default value of the DEM Invert is off, though it isrequired to set to on depending when the frequency bandand shift frequency are used as shown in following table.When corresponding ODU is connected with the IDU, thechange of setting is necessary via LCT. For the settingprocedure, refer to 3.4 Equipment Setting and Monitoringin 3. OPERATION in Section III MDP EquipmentDescription.

2. SYSTEM CONFIGURATION
This system consists of TRP-[ ]G-[ ] Transmitter-Receiver (Outdoor Unit(ODU)) (see Fig. 2-1) and MDP-[ ]MB-[ ] Modulator-Demodulator(Indoor Unit (IDU)) (see Fig. 2-2, Fig. 2-3 (1/2) and Fig. 2-3 (2/2).
The [ ]GHz (2/4/8/16 x 2 MB) MB digital radio system is used tocommunicate from 2 to 16 data streams at 2.048 Mbps and/or up to 2channels 10BASE-T/100BASE-TX LAN signals between two stations.
The system block diagrams of 2/4/8/16 x 2 MB systems are shown in Fig.2-4 and Fig. 2-5.

5. ALARM AND CONTROL
The simplified alarm and control functions are described in accordancewith the alarm indication and reporting, and network management.
5.1 Alarm Indication and Reporting
Alarm indication and reporting function are provided with the IDU. Alarmsignals initiated by detection circuits on the ODU are sent to the IDU.Therefore the alarm indicator for the ODU is located on the front panel ofthe IDU. The alarm indication for the IDU is also indicated by thecorresponding alarm indicator on the IDU. When the equipment isoperating normally, the alarm indicators on the IDU stay unlit. When anabnormal condition occurs, the related alarm indicator is lit and a remotealarm report is made (see Table 2-3 in MDP Equipment Description).
