In this user interface, you can collect statistics on power and bit error rates (BERs) of the NEs at both ends of a microwave link and view the statistics in a graph or table. You can also quickly query the current and historical performance of the two NEs, which improves routine maintenance efficiency.
In the NE Explorer, select a microwave link and choose from the Function Tree. Click the Current Performance tab.
In the NE Explorer, select a microwave link and choose from the Function Tree. Click the History Performance tab.

Parameter |
Value |
Description |
|---|---|---|
Power to Be Received(dBm) |
-90.0 to -20.0 Default: -10.0 |
Indicates the expected receive power of an outdoor unit (ODU). This parameter is used in the antenna alignment stage. After this parameter is set, the NE automatically enables the antenna misalignment indicating function. When the antenna misalignment indicating function is enabled, if the actual receive power of the ODU is 3 dB lower than the power expected to be received, the ODU indicator on the IF board connected to the ODU blinks yellow (300 ms on, 300 ms off), indicating that the antenna is not aligned. After the antenna alignment, after the state that the antenna is aligned lasts for 30 minutes, the NE automatically disables the antenna misalignment indicating function. When this parameter takes the default value, the antenna misalignment indicating function is disabled. |
Actual Receive Power(dBm) |
For example: -66.3 |
Indicates the actual receive power of the ODU. |
Transmit Power(dBm) |
For example: 1.0 |
Indicates the transmit power of the ODU. This parameter cannot be set to a value that exceeds the nominal power rang of the ODU or a value that exceeds Maximum Transmit Power(dBm). |
Actual Transmit Power(dBm) |
For example: 10.0 |
Indicates the actual transmit power of the ODU. If the automatic transmit power control (ATPC) function is enabled, the queried actual transmit power may be different from the preset value. |
IF_ES(s) |
For example: 40.0 |
Indicates the errored second (ES) of a microwave link. ES refers to a second in which one or more errored blocks are detected. |
IF_SES(s) |
For example: 39.0 |
Indicates the severely errored second (SES) of a microwave link. SES refers to a second in which 30% or more than 30% errored blocks exist or at least one SDP exists. SDP is the period in which the BER of all the consecutive blocks in a period of less than four consecutive blocks or 1 ms (the longer period is applied) is equal to or higher than 10-2 or the signal is lost. |
IF_CSES(s) |
For example: 3.0 |
Indicates the consecutive severely errored second (CSES) of a microwave link. CSES refers to a second in which the SES occurs continuously for less than 10 seconds. |
IF_UAS(s) |
For example: 13434.0 |
Indicates the unavailable second (UAS) of a microwave link. The unavailable time begins at the onset of 10 consecutive SESs, with the 10 SESs included. When SESs disappear for 10 consecutive seconds, the available time begins from the eleventh second, with the previous 10 seconds included. |
IF_BBE(block) |
For example: 11060.0 |
Indicates the background block error (BBE) of a microwave link. BBE refers to the errored blocks excluding the errored blocks in the unavailable and severely errored seconds. |
FEC_BEF_COR_ER |
For example: 10.0 |
Indicates bit error rate before forward error correction (FEC). This event indicates the impact of the external environment on the transmission. |
Lapsed Time(hh:mm:ss) |
For example: 08:02:44 |
Indicates the elapsed time in the current performance monitoring period. |
Source |
For example: NE675-7-IFX |
Indicates the source of a microwave link. |
Sink |
For example: NE(126-8103)-4-ISU2 |
Indicates the sink of a microwave link. |
Resolution |
15-Minute, 24-Hour Default: 15-Minute |
Displays the performance monitoring period. |
From/To |
For example: from 2011-06-20 00:00:00 to 2011-06-21 00:00:00 |
Sets the start time and end time of the performance monitoring. |
NE Name |
For example: NE675/126-675 |
Indicates the NE that a microwave link belongs to. |
Max Rx Power(dBm) |
For example: -20.0 |
Indicates the maximum receive power in a performance monitoring period. |
Min Rx Power(dBm) |
For example: -90.0 |
Indicates the minimum receive power in a performance monitoring period. |
Max Tx Power(dBm) |
For example: -20.0 |
Indicates the maximum transmit power in a performance monitoring period. |
Min Tx Power(dBm) |
For example: -90.0 |
Indicates the minimum transmit power in a performance monitoring period. |
Max Rx Power(dBm) in Query Period |
For example: -20.0 |
Indicates the maximum receive power in query period. |
Min Rx Power(dBm) in Query Period |
For example: -90.0 |
Indicates the minimum receive power in query period. |
Average Rx Power(dBm) |
For example: -55.0 |
Indicates the average receive power in a performance monitoring period. |
Display Format |

Specifies how the performance event values in a performance monitoring period are displayed. |
End Time |
For example: 2011-06-14 00:00:00 |
Displays the time to end performance monitoring. |
