2.1 TUMR26 alarms

The TUMR26 card unit has 6 alarms that may occur depending on current unit status:

Temperature Alarm: occurs in case the unit temperature goes over 75C or below 0C.

Power Supply Alarm: occurs in case the sub-rack main supply source voltage goes over 14Vor it goes below 10V.

Vcc Alarm: occurs in case of internal RF stage and Signal Processor power supply circuitmalfunctioning.

Synchronization Lost: occurs in case the Signal Processor is not able to correctly detectWiMax preamble parameters resulting in missing system synchronization

1.

Internal bus alarm: occurs in case the internal Signal Processor communication is

malfunctioning, no configuration changes are possible if this alarm is active. (Note: a unitReboot

2command may fix the problem)

Over Power WiMax: occurs in case the RF input power exceeds the maximum value of theinput power operating range

3.

1In case the Synchronization Lost alarm is active please check the TUMR26 configuration (it is recommended

to configure all settings in AUTO and to check the Channel Frequency configuration) and the input WiMax Rfsignal power that should be in the range [0..20dBm].2Rebooting the TUMR26 causes a temporary sub-rack I2C bus alarm that is automatically cleared once the unit

finishes its startup (it takes about 30 seconds).3See TUMR26 technical specification sheet. This feature has not been implemented in TUMR26 prototypes.

2.2 TUMR26 status sett ings

The TUMR26 has 5 statuses that show current unit configuration, 4 of them are user settable:

Signal Processor: ON means that the internal processor module is active; OFF means thatthe internal processor module has been turned off.

FFT Size: it is a parameter used to decode the WiMax preamble, all FFT Size settings (Auto,512, 1024, 2048) are mutually exclusive the latest one changed to Selected makes all theother Not Selected. The factory setting is Auto FFT Size this means that actual setting isautomatically selected by Signal Processor.

Cyclic Prefix: it is a parameter used to decode the WiMax preamble, all Cyclic Prefix settings(Auto, 4, 8, 16, 32) are mutually exclusive the latest one changed to Selected makes all theother Not Selected. The factory setting is Auto Cyclic Prefix this means that actual setting

is automatically selected by Signal Processor.

Auto DL Symbols: if this setting is Selected the Signal Processor automatically determinesthe Number of DL Symbols needed for preamble decoding, the correspondent manualconfiguration is disabled. If this setting is Not selected the current Number of DL Symbolscna be changed manually. (see TUMR26 analogical settings paragraph). The factory settingis Auto DL Symbols = Selected.

Store Signal Processor Config.: in order to make current configuration permanent (notaffected by a unit reboot) it is required to select this setting and press SUBMIT.

2.3 TUMR26 analogical monitors and settings

The TUMR26 has 1 read only monitor, the unit Temperature, and 2 user settable parameters:

Channel Frequency: is the WiMax channel center frequency that is used by SignalProcessor to detect and decode the signal preamble. There are 2 available frequencyranges: 2.5GHz range from 2496 to 2599 MHz and the 2.6GHz range from 2600 to2690GHz. The user can select the preferred one changing the Frequency Range value (2.5or 2.6 GHz] , within the selected range the user should type the frequency that matches theinput signal rounded to the nearest lower integer value (MHz) then , if needed, the channelfrequency can be adjusted using the Channel Frequency Adjust parameter with aresolution of 200KHz. For instance if the desired frequency is 2635.4MHz the user shouldperform the following steps:

1. refresh the window by clicking on refresh button or pressing F5 on keyboard,

2. type 2.6 in the Frequency Range setting text box,

3. type 2635 in the Channel Frequency (2.6GHz) setting text box,

4. type 400 in the Channel Frequency Adjust setting text box

5. click on SUBMIT.

Remember to Store Signal Processor Config. in order to make current configuration permanent

The factory configuration is: Channel Frequency = 2600.0MHz

DL Symbols: is a parameter used by Signal Processor to decode the WiMax preamble. If theAuto DL Symbols setting is enabled the actual DL Symbols may be different from thevalue that is shown in the related text box. In case of trouble (Eg, the Synchronization Lost

alarm is active) the user may try changing this parameter. For instance if the desired numberof DL Symbols is 29 the user should perform the following steps:

1. Disable the Auto DL Symbols , if it enabled enabled, from the status section

2. refresh the window by clicking on refresh button or pressing F5 on keyboard,

3. type 20 in the DL Symbols text box,

4. type 9 in the DL Symbols Adjust text box,

5. click on SUBMIT.

The new DL Symbols value is immediately used by Signal Processor to decode WiMaxpreamble. Remember to Store Signal Processor Config. in order to make currentconfiguration permanent.

The factory configuration is Auto DL Symbols = enabled

3.1 TPOI26 alarms

The TPOI26 card unit has 6 alarms that may occur depending on current unit status:

Temperature Alarm: occurs in case the unit temperature goes over 75C or below 0C.

Power Supply Alarm: occurs in case the sub-rack main supply source voltage goes over 14Vor it goes below 10V.

Vcc Alarm: occurs in case of internal power supply circuit malfunctioning.

DL WiMax band alarm: occurs in case one or more internal Downlink RF amplifier stages aremalfunctioning (or completely turned off due to Vcc Alarm).

Synchronization Lost: occurs in case the input synchronization signal is missing4.

Over Power WiMax: occurs in case the RF input power exceed the absolute maximum valueof the input power

3.2 TPOI26 status sett ings

The TPOI26 has 1 status configuration that may be changed according to current systemconfiguration:

DL backward compatibility: is a special configuration parameter that allows user change unitmaximum gain. In case the TPOI26 output RF signal feeds ION-B optical master unit(TFLN2504-4) with old RF auxiliary channel specification

6it is required to change maximum

4Please check that the front panel RJ11 connector is correctly hooked to a TUMR26 front panel RJ11

connector and that a valid WiMax signal is feeding TPOI26.5For details refers to TPOI26 technical specification sheet .

6Starting from 2008 ION-B master optical card RF specification has been improved especially regarding the

auxiliary channel leveling this results in different TPOI26 maximum gain configuration depending on which kindof TFLN is fed. Please check the all TFLNs serial numbers in order to determine whether they were released

with old or new RF specification: if the serial number isgreater than 00008XXXXXXX the unit has newRFspec. and no TPOI changes are required otherwise it is needed to change default DL backward compatibility to

Max Gain: 18dB.


12/16


gain from 15 to 18dB. The factory setting is DL backward compatibility = Max Gain: 15dBtherefore by default the TPOI26 is compatible to latest optical master unit RF specification.

Fig. 9: TPOI-26 configuration window STATUS section

3.3 TPOI26 analogical monitors and settings

The TPOI26 has 2 read only analogical monitors:

Temperature: is the unit internal temperature in C.

DL Output Power: is the WiMax channel power measured at the output of the TPOI26

It has also 2 user settable parameters:

Downlink WiMax Attenuation: is the downlink gain adjustment due to system calculation inorder to compensate RF input level or following system stage loss. The factory attenuationis 0dB (maximum downlink gain ) and the available attenuation range is from 0 to 27dB

(even if the SW reports a range of 0~30dB); in case the DL backward compatibility isactivated ( Max Gain: 18dB) then the actual available attenuation range changes in 0 to30dB

7.

Uplink WiMax Attenuation: is the uplink gain adjustment due to system calculation in order tocompensate RF level in the uplink path due to previous system stage loss. The factoryconfiguration is 0dB ( maximum uplink gain) and the available attenuation range is alwaysfrom 0 to 30dB.
