13 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 12

14 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 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. 13

31 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. 4.2 Electrifying Test Figure 5 Rack mounting IDU 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 One Way BER Test: (Fading-less) A station to transmit and B station to receive No BER error occurs. B station to transmit and A station to receive No BER error occurs. 30

No BER error occurs. Or route the other way around (loop from station B to station A). Figure 7 Loopback BER Test 31

33 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. 32
