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 transmission digital microwave radio system. Included herein are notice for system operation, system configuration, system performance, RF channel assignment, 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 power switch to on/off, it must be pulled out power switch lever knob to unlock the switch lever.

2. After turning ON the equipment, wait at least 10 seconds or more before turning it OFF again. Repeatedly turning the power ON and OFF within a short interval may cause the IDU to fail.

3. Do not disconnect I/F cable between the IDU and the ODU in power ON condition, to avoid damaging the IDU and ODU. Do not connect/disconnect the I/F cable with IDU power ON, turn IDU power OFF before connecting/disconnecting the I/F cable.

4. Persons performing servicing must take necessary steps to avoid electro-static discharge which may damage the modules on the IDU or cause error. Wear a conductive wrist strap connected to the frame ground (FG) terminal on the front of the equipment shelf. This will minimize static build-up during servicing.

5. In back -to-back connection, the interface conditions of the 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 cable connection 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 radio frequency in the local station at first, you can not change radio frequency of the opposite station using PC menu at the local station. Because the opposite station can not receive the control signal to be set radio frequency.

1-1

GENERAL ROI-S04604

8. The equipment is applied only SEL V (Safety Extra-Low Voltage) power supply, do not apply a voltage that varies sharply. This may cause abnormal operation.

9. In 1+1 system, when neither No.1 nor No.2 channel is working, first set the OPE SEL switch to the desired (No.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.

In 1+1 system, when either No.1 or No.2 channel is working, set the OPR 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.

10. In 1+1 system, when demounting the ODU from the antenna direct mounting HYB, mount the attached SHORT PLATE to the demounted port of the HYB to avoid RF power leaking from the hybrid and for waterproofing.

11. In 1+1 system, to avoid occurrence of bit errors due to microphonic properties, when installing the standby ODU on to the antenna direct mounting HYB, protect the working ODU from mechanical knocks.

12. In 1+1 system, when the SW UNIT is replaced with a spare, the service is interrupted.

13. Before the start of maintenance, including operation of the 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 and ODU, using circuit tester, check that the resistance of the I/F cable between center conductor and insulation is more than 100 MΩ.

15. When the LAN INTFC is used, the domestic is an environment where the use of broadcast radio and television receivers may be expected within a distance of 10 m of the apparatus concerned.

16. 16x2MB bit rate is not supported on MDP-17MB-3/4A.

1-2

ROI-S04604 GENERAL

17. It is recommended that you connect the IDU to ODU after the TX/RX frequency and TX power control setting has been set on the IDU.

This process is most important for the following ODUs that may 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 is required to set to on depending when the frequency band and shift frequency are used as shown in following table. When corresponding ODU is connected with the IDU, the change of setting is necessary via LCT. For the setting procedure, refer to 3.4 Equipment Setting and Monitoring in 3.

1.2 Information About Operation Mode Label

Note that the following information for the Pasolink Mode is labelled on the ODU/Package which identifies the operation mode of the Pasolink Mx.

This information can be passed for the unlabelled ODU/Package.

1.2.1 TRP-( )G-3A PASOLINK ODU

For the TRP-( )G-3A PASOLINK ODU, though there is a package label, the Pasolink Mode checking section of the package label is not used. (The check box of the Pasolink Mode is not marked always, or meaningless.)

1.2.2 TRP-( )G-5A PASOLINK Mx ODU

For the TRP-( )G-5A Pasolink Mx ODU, there are two operation modes of the PASOLINK Mx and the PASOLINK that either can be selected through the PASOLINK Mx IDU using the LCT.

1. The TRP-( )G-5A PASOLINK Mx ODU which has been set to the Pasolink Mode (optional) at the factory, to identify the operation mode in delivery, the check box of the package label is marked and a transparent green label is put on to the ODU name plate. (The change of the operation mode of the ODU can be performed at onsite.) *1

Note *1: After the operation mode is changed from the PASOLINK to the PASOLINK Mx at onsite, the check mark or Pasolink Mode identification label is invalid.

The ODU can be connected with the IDU under the operation mode in shipment as listed in the following Table.

If an abnormal connection occurs between the IDU and ODU, perform the reset-up of the operation mode using the PASOLINK Mx IDU and check the operation.

When the ODU is setup to the Pasolink Mode in shipment, the check box of the following package label is marked. The green label is put on to the name plate on the ODU for the operation mode identification also.

ROI-S04604 ALARM AND CONTROL

5. ALARM AND CONTROL

The simplified alarm and control functions are described in accordance with the alarm indication and reporting, and network management.

5.1 Alarm Indication and Reporting

Alarm indication and reporting function are provided with the IDU. Alarm signals 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 of the IDU. The alarm indication for the IDU is also indicated by the corresponding alarm indicator on the IDU. When the equipment is operating normally, the alarm indicators on the IDU stay unlit. When an abnormal condition occurs, the related alarm indicator is lit and a remote alarm report is made (see Table 2-3 in MDP Equipment Description).

Fig. 5-1 Simplified Block Diagram of Alarm and Control

5.2 Network Management (Optional)

Configuration of network management system (NMS) is shown in Fig. 5-2. Network management system (PNMS) is connected with NMS/RA of IDU, and network management terminal (PNMT) is connected with LA PORT in IDU to provide monitor and control of the PASOLINK equipment and monitoring of actual microwave link. Communication with the remote station units is performed using one of DSC channels.
