Microwave Link Configuration

The U2000 Web LCT displays the parameters of the two NEs at the two ends of a microwave link in the same window and associates the settings of the same key parameters on the two NEs. In this manner, the microwave link configuration efficiency is improved. In this user interface, you can set the parameters on the NEs at the two ends of a microwave link.

Navigation Path

In the NE Explorer, select the NE and choose Configuration > Microwave Link Configuration from the Function Tree. Select an IF board in the drop-down list.

Guideline

The microwave link must be created.
Unlike other operations in the NE Explorer, the HOP management involves multiple NEs. Hence, it requires that you have logged in to NEs at both ends of links.

Shortcut Menu Description

Menu Item	Description
Clear	Clears switching for the selected board.
Force to Protection	Forces the service to switch from the working board to the protection board. This switching is performed regardless of the protection board state, unless the protection board is satisfying a higher priority bridging request.
Force to Working	Forces services to switch from the protection board to the working board. This switching is performed regardless of the working board state, unless the working board is satisfying a higher priority bridging request.
Manual to Protection	Performs manual switching from the working board to the protection board. If the protection board is normal, the switching takes place. If the protection board fails or must satisfy a switching request of higher priority, the switching does not take place.
Manual to Working	Performs manual switching from the protection board to the working board. If the working board is normal, the switching takes place. If the working board fails or must satisfy a switching request of higher priority, the switching does not take place.
Lockout of Protection	The switching request for the board is denied, but the reversion of switching is allowed.
Query Switch Status	Queries the current protection switching status from the NE.

Parameters

Field		Value	Description
Basic Parameters	RSL	Example: 2dB	Displays the received signal level of the ODU.
	TSL	Example: 2dB	Displays the transmitted signal level of the ODU.
	Protection	1+0, 1+1	Indicates the protection type.
	Link Working Mode	HSB, SD, FD	Selects the working mode for the IF 1+1 protection group. In the 1+1 HSB protection mode, the equipment provides a 1+1 hot standby configuration for the IF board and ODU at the two ends of each hop of a microwave link to realize the protection. In the 1+1 FD protection mode, the system uses two channels that have a frequency spacing between them, to transmit and receive the same signal. The opposite end selects signals from the two received signals. With the 1+1 FD protection, the impact of the fading on signal transmission is reduced. In the 1+1 SD protection mode, the system uses two antennas that have a space distance between them, to receive the same signal. The equipment selects signals from the two received signals. With the 1+1 SD protection, the impact of the fading on signal transmission is reduced. The 1+1 FD protection mode and 1+1 SD protection mode are compatible with the 1+1 HSB switching function. Set this parameter according to the planning information.
	Working Board	slot number-board name	This parameter specifies the working board of the protection group.
	Protecting Board	slot number-board name	This parameter specifies the protecting board of the protection group.
	Revertive Mode	Revertive, Non-Revertive	Specifies whether to switch back to the original working service after removing the fault. Select Revertive to switch back to the working service, or select Non-Revertive not to switch back to the working service any longer. When this parameter is set to Revertive, the NE that is in the switching state releases the switching and enables the former working channel to return to the normal state some time after the former working channel is restored to normal. When this parameter is set to Non-Revertive, the NE that is in the switching state keeps the current state unchanged unless another switching occurs even though the former working channel is restored to normal.
	WTR Time (s)	300 to 720	Sets the wait-to-restore time. Refer to the period of time starting when it is detected the working board returns to normal and ending when the working board is switched back after the protection switching. This parameter is valid only when Revertive Mode is set to Revertive. When the time after the former working channel is restored to normal reaches the set wait-to-restore (WTR) time, a revertive switching occurs. It is recommended that you use the default value.
	Enable Reverse Switching	Enabled, Disabled	When both the main IF board and the standby IF board at the sink end report service alarms, they send the alarms to the source end by using the MWRDI overhead in the microwave frame. When this parameter at the source end is set to Enable and the reverse switching conditions are met, the IF 1+1 protection switching occurs at the source end. This parameter is valid only when Working Mode is set to HSB or SD. In 1+1 FD mode, this parameter is read-only and its default value is Disabled. It is recommended that you use the default value.
	XPIC	checked, unchecked	Specifies whether the XPIC function is enabled. NOTE: Set IF Channel Bandwidth before enabling the XPIC function. If XPIC is enabled, the Guaranteed E1 Capacity(V/H), Data Service Bandwidth(Mbit/s)(V/H), Enable E1 Priority(V/H), and Full E1 Capacity(V/H) parameters are available. Values in the first and second text boxes next to each of them are for the V and H directions respectively.
	Link ID	1 to 4094	Indicates the link ID.

	Polarization Direction - H	slot number-board name	Indicates the H-direction IF board on the local NE of an XPIC protection group.
	Adjacent NE Link ID	1 to 4094	Indicates the link ID of the adjacent NE in an XPIC working group.
	Synchronize to the adjacent NE	Synchronize	Indicates that the local NE configurations are synchronized to the adjacent NE in an XPIC working group after XPIC is enabled. NOTE: If the adjacent NE exists, the adjacent NE ID, for example, NE(9–123), is displayed below Synchronize to the adjacent NE. If the adjacent NE does not exist, Not Exist is displayed below Synchronize to the adjacent NE.
IF	IF Service Type	Hybrid(Native E1+ETH), Hybrid(Native STM-1+ETH), SDH	Sets the IF service type. Hybrid(Native E1+ETH) indicates that the Hybrid services consisting of native E1 services and Ethernet services are transmitted currently. Hybrid(Native STM-1+ETH) indicates that the Hybrid services consisting of native STM-1 services and Ethernet services are transmitted currently. SDH indicates that the SDH services are transmitted currently.
	IF Channel Bandwidth	For example: 56MHz	Specifies the IF channel bandwidth of the port. The channel frequency bandwidth, that is, channel bandwidth or channel interval, depends on the spectrum of the signal transmitted, or depends on the capacity and the modulation mode used.
	AM Status	checked, unchecked	Enables or disables the AM.

This parameter is configurable only when AM Status is set to Enable. NOTE: This parameter can be set to 512QAM, 1024QAM, QPSKStrong, 16QAMStrong, 512QAMLight, or 1024QAMLight only when Running Mode of the board is IS3.
	Full AMAC Capacity	QPSK/11Mbit/s, 16QAM/21Mbit/s, 32QAM/25Mbit/s, 64QAM/32Mbit/s, QPSKStrong_250M, QPSKStrong_500M	Specifies the highest-order modulation scheme that the AMAC function supports.

	Guaranteed E1 Capacity Guaranteed E1 Capacity(V/H)	For example: 5	Specifies the minimum number of E1 services that can be transmitted in hybrid mode. If AM Enable Status is set to Enabled, this parameter needs to be set according to IF Channel Bandwidth, Modulation Mode of Guaranteed AM Capacity, and the actually transmitted services. If AM Enable Status is set to Disabled, this parameter needs to be set according to IF Channel Bandwidth, Manual Modulation Mode, and the actually transmitted services. For the ISU2 and ISX2 boards, this parameter is available when IF Service Type is Hybrid(Native E1+ETH). For the ISX2 boards, the Guaranteed E1 Capacity may vary with the XPIC Enabled value (Enabled or Disabled) although the IF channel bandwidth and modulation mode are the same. The Guaranteed E1 Capacity value varies with boards. For details, see technical specifications of the boards in the related device documentation. NOTE: You need to check the maximum capacity that can be specified currently to ensure that the value of this parameter does not exceed the limit.
	Data Service Bandwidth(Mbit/s) Data Service Bandwidth(Mbit/s)(V/H)	For example: 33.881	Displays the bandwidth of data service.

	T/R Spacing(MHz)	0 to 4294967.295	Sets the interval between the transmit frequency and the receive frequency of an ODU board to avoid mutual interference.
	ATPC	checked, unchecked	When the ATPC is enabled, according to the current receive power of the ODU and the set ATPC thresholds, the ATPC module inserts the ATPC overhead. According to the ATPC overhead, the opposite ODU adjusts the transmit power. When the ATPC is disabled, the ATPC module does not insert any ATPC overhead.
	ATPC Upper Threshold (dBm)	Valid Values:-85.0 to -20.0 Default Value:-45.0	The parameter value can be accurate to only within 0.1 dBm. In normal cases, an ODU should operate at a low transmitted power as long as services are stable. The ATPC Upper Threshold (dBm) parameter is used to prevent the transmitted power of the opposite ODU from being too high. Hence, set the ATPC Upper Threshold (dBm) parameter to a value as small as possible. NOTE: The value of the ATPC Upper Threshold (dBm) parameter must be 15 dB more than the value of the ATPC Lower Threshold (dBm) parameter.
	ATPC Lower Threshold (dBm)	Valid Values:-90.0 to -25.0 Default Value:-70.0	You can set the ATPC Lower Threshold (dBm) parameter to any integer from -90.0 through -25.0. In actual application, the value of the ATPC Lower Threshold (dBm) parameter is the lowest received power of the local ODU that ensures stable microwave services. NOTE: The value of the ATPC Lower Threshold (dBm) parameter must be 15 dB less than the value of the ATPC Upper Threshold (dBm) parameter.
