Section 3 Supervision Controls

3.1 Operation Procedure

WaveLink PDH can be operated in three forms

1) LCD panel;

2) HyperTerminal;

3) NMS port.

IDU without front LCD display should be system controlled by HyperTerminal

Controls can be monitored via the LCD panel or the HyperTerminal

3.2 HyperTerminal settings

User can use HyperTerminal on Windows to manage the equipment through

supervision interfaces. The main content of control management includes: Login

management, Data link testing, system alert, power and environmental status,

equipment status, alert management, equipment maintenance and parameter

settings.

Parameters of supervision interface:

Supervision interface adopts RS-232 to interface: Full duplex, Baud rate=19200

b/s; Stop bits=1.5 or 2; Data bits=8; Parity=None; Flow control=None.

Main functions

Login authorization management

To stop illegal accessing the management system, the password management

was used in the system. User can change the password. Special attention: User

should log-off the system after operating to avoid illegal user from accessing.

(Default: No Password, press ENTER key to login).

Voltage status

Users can monitor the internal operating voltage. The equipment will show relative

alert when the voltage of some group out of Spec.

Data-link test and Status warning

Users can test and review the Branch Link and Multiplex Link of each E1, it

includes Mux-link loopback test, interrupt check and AIS warning; Mux-link BER

test、automatic link switch and system delay re-start.

Equipment status and Alarm management

Users can check the equipment status and alarm while operating, and define the

13

notify way and alarm level.

Equipment Maintenance and parameter setting

Users can save the parameters to prevent parameter losing after power off. Users

can set the parameter quite easily, such as to open/close the branch link; back up

selection of multiplex link; set/change password and equipment name; save/reload

equipment parameters

Equipment Maintenance includes: hardware module troubleshooting and link

testing. Do Troubleshooting to find out the root causes of hardware mal-functions

quickly.

Remote control

Users can control the remote equipment through the local equipment.

3.3 Operating HyperTerminal

3.3.1 Parameter Setting.

HyperTerminal operating steps:

Step 1:

Run “Start\All programs\Accessories\Communications\HyperTerminal” in Windows

OS.

Step 2:

Select one port and set the parameter for communication:

Baud rate=19200 b/s; Stop bits=1; Data bits=8; Parity=None; Flow control=None.

Section 4 Field Installation

4.1 IDU Installation

The indoor unit (IDU) shall be installed on a standard rack inside the link stations.

The power and grounding wires should be well connected to meet their individual

design specs. Make sure the power to be supplied is safely rated for the IDU.

Figure 5 Rack mounting IDU

4.2 Electrifying Test

After adjusting the antennas, the link devices in corresponding stations can be

energized for running. If system runs in normal conditions, there will be no warning

indicators flashing.

4.3 BER Test

4.3.1 One Way BER Test: (Fading-less)

A station to transmit and B station to receive – No BER error occurs.

4.3.2 Loopback Test: (Fading-less)

Loop start from station A and conduct BER test at loop end of station B. No BER

error occurs. Or route the other way around (loop from station B to station A).

Section 5 Maintenance and Troubleshooting

5.1 Maintenance Check

Check on Power;

Check cable connections;

Check battery power (should be within –48v ±20%);

Check light indicators;

Check weather conditions (temperature, humidity, etc.)

Conduct Maintenance check at least once a month.

5.2 Troubleshooting

If something wrong with the equipment, please do not dismantle it without getting authorization from supplier. Always check thoroughly by following the recommended steps: Use monitoring software or user guide to check (Failure analysis flow chart)

Same way to check the other link

Check failure symptoms at both links

Find out root causes at both links

If user wants to fix the failure, please consult experienced technical staff for getting

step by step problem-solving suggestions.

5.3 Maintenance Notes

Maintenance process should be done by or under the guidance of authorized

Professional engineers.

Re-start the equipment (after power-off) and wait for 30 seconds, the

equipment should operate back to normal.

During maintenance session, parameters could be changed or revised. Be

sure to change back to initial status after the completion of maintenance

session.

Section 6 Packaging and Storage

6.1 Equipment ID

Product Name, Model No., Serial No. must be clearly marked in a designated area

on the Product.

6.2 Packaging requirements

Packaging Check list

User Guide

Inspection Certificate

6.3 Shipment and Storage Handlings

Follow packaging specs to choose the packaging material and packaging

procedure to pack the finish product accordingly.

User Guide, Inspection Certificate and Packing List should be included in box.

Product would be delivered via airway, land and sea expressways by avoiding any

hazardous situations such as: rain, flood, storm, snow or any possible natural

impacts.

Require good ventilation system in the storage room. Keep storage temperature in

a range of -10~+40 and control humidi℃ ty to be lowered than 85% and keep the

products away from any hazardous chemical compounds or toxic gas.
