ODU Interface

In this user interface, you can query and set parameters for an ODU interface.

Navigation Path

In the NE Explorer, click a board and choose Configuration > ODU Interface from the Function Tree.
In the NE Explorer, click a board and choose Configuration > RF Interface from the Function Tree.

NOTICE:

Setting the loopback status of the ODU interface to inloop or outloop may interrupt services and the ECC. Exercise caution before performing this function.

Guideline

Note the following when setting the TX High Threshold (dBm) and TX Low Threshold (dBm) parameters.
- When the actual launched power of the ODU is higher than TX High Threshold (dBm), the system records the time when the actual launched power is higher than TX High Threshold (dBm) and the time when the actual launched power is higher than TX Low Threshold (dBm) as performance events.
- When the actual launched power of the ODU is within the range from TX Low Threshold (dBm) to TX High Threshold (dBm), the system records the time when the actual launched power of the ODU is higher than TX Low Threshold (dBm) as a performance event.
- When the actual launched power of the ODU is lower than TX Low Threshold (dBm), no record is saved.
- The TX High Threshold (dBm) and TX Low Threshold (dBm) parameters are valid only when the ATPC function is enabled.
Note the following when setting the RX High Threshold (dBm) and RX Low Threshold (dBm).
- When the actual received power of the ODU is lower than RX Low Threshold (dBm), the system records the time when the actual received power is lower than RX High Threshold (dBm) and the time when the actual received power is lower than RX Low Threshold (dBm) as performance events.
- When the actual received power of the ODU is within the range from RX Low Threshold (dBm) to RX High Threshold (dBm), the system records the time when the actual received power of the ODU is higher than RX Low Threshold (dBm) as a performance event.
- When the actual received power of the ODU is higher than RX Low Threshold (dBm), no record is saved.

Parameters

Field	Value	Description
Board	For example: NE56-15-ODU	Displays the name of a board.
Transmit Frequency (MHz)	0-4294967.295	Sets and queries the transmission frequency for an ODU board. The ODU board can properly transmit and receive signals only when the frequency of the transmitter and the frequency of the received at two ends are matched. NOTE: The transmit frequency is 0 by default for an unconfigured ODU interface.
T/R Spacing (MHz)	0-4294967.295	Sets the spacing between the transmission frequency and the received frequency for an ODU board, to avoid mutual interference. The T/R spacing of the ODU should be set to the same value at both the ends of a microwave link.
Actual Transmit Frequency (MHz)	For example: 23025	Queries the actual transmission frequency for a board.
Actual Receive Frequency (MHz)	For example: 22017	Queries the actual received frequency for a board.
Actual T/R Spacing (MHz)	For example: 1008	Queries the actual spacingl between transmission and receiving for a board.
The range of the frequency point (MHz)	For example: [2300.8, 2332.2]	Queries the working range of a frequency point.
Maximum Transmit Power (dBm)	For example: 35.0	Sets the maximum transmit power for the board.
Transmit Power (dBm)	-10.0 to 35.0	Sets the transmit power for a radio frequency port.
Power to Be Received (dBm)	For example: -20.0	Sets the received power.
TX High Threshold (dBm)	For example: 35.0	Sets the high threshold of the transmit power.
TX Low Threshold (dBm)	For example: -10.0	Sets the low threshold of the transmit power.
RX High Threshold (dBm)	For example: -10.0	Sets the high threshold of the received power.
RX Low Threshold (dBm)	For example: -90.0	Sets the low threshold of the received power.
Actual Transmit Power (dBm)	For example: 10	Queries the actual transmit power for a radio frequency port. When you start the ATPC, the actual transmit power that is queried may be different from the one you set. NOTE: If the standby ODU does not transmit the RF signal, the query result of the parametor is mute.
Actual Receive Power (dBm)	For example: -50	Queries the received power.
Actual Transmit Power Range (dBm)	For example: [-6, 24]	Queries the range of the actual transmit power.
Frequency (GHz)	For example: 7	Queries the working frequency band for the ODU equipment.
Equipment Type	Low Capicity, High Capicity	Queries the type of the ODU equipment. Indicates the transmission capacity only and is irrelevant to the type of transmitted service.
T/R Spacing (MHz)	For example: 161000	Queries the T/R spacing for the ODU equipment.
Intermediate Frequency Bandwidth (MHz)	For example: 13	Queries the intermediate frequency bandwidth for the ODU equipment.
IF Bandwidth Type	Fixed, Max	Queries the intermediate frequency bandwidth type for the ODU equipment.
Station Type	Tx low, Tx high	Queries the settings of the high station and the low station for the ODU equipment.
Transmission Power Type	Standard Power Output, High Power Output	Queries the power output level for the ODU equipment.
Produce Time	For example: 2006-6	Queries the time when the ODU equipment is produced.
Produce SN	For example: 0-0	Queries the manufacturing serial number and the manufacturer code of the ODU equipment.
RF Loopback	Non-LoopBack, Inloop Default: Non-LoopBack	Sets the loopback status of a radio frequency port on the equipment. Non-Loopback is usually selected. Non-Loopback refers to the normal status. It is not required to set loopback during normal equipment operation. Inloop means that the input signal returns from the ODU board of the destination NE along the original trail. NOTICE: This function is usually used to locate faults for various IF interfaces. Performing loopback on an intermediate frequency interface is a diagnosis function which may affect services of related ports. Exercise caution before performing this function.
Configure Transmission Status	mute, unmute	Sets the transmission status of a radio frequency transmitter.
Actual Transmission Status	mute, unmute	Queries the transmission status of a radio frequency transmitter.
Antenna Polar Weid	V, H Default: H	Sets the antenna polar weid.
Factory Information	Character string	Queries the manufacturing information of the ODU.
Remarks	Character string	Queries the remark information for the ODU equipment.
