Basic Information About Microwave Links

Based on the spectrum allocation on the radio network and the required radio transmission capacity, you can obtain the basic information about microwave links as shown in Table 1.

**Table 1** Basic information about microwave links
Parameter	Link 1	Link 2
Link ID	301	302
Tx high site	NE33	NE33
Tx low site	NE32	NE34
Tx frequency at the Tx high site (MHz)	14967	14930
Tx frequency at the Tx low site (MHz)	14547	14510
T/R spacing (MHz)	420	420
Channel spacing (MHz)	14	7
RF configuration mode	1+1 HSB	1+0
Polarization Direction	V (vertical polarization)	H (horizontal polarization)

NOTE:

The link planning information that is not associated with the configuration of IDU (except for the polarization direction) is not provided in this example.

Hybrid/AM Attribute Information

According to the capacity of E1 and Ethernet services and the availability requirement, you can calculate the Hybrid/AM attribute information, as provided in Table 2.

**Table 2** Hybrid/AM attribute information
Parameter	Link 1	Link 2
Capacity of high-priority services (Mbit/s)	10	5
Capacity of low-priority services (Mbit/s)	43	19
AM enable status	Enabled	Enabled
Modulation mode of the guarantee AM capacity	QPSK	QPSK
Modulation mode of the full AM capacity	64QAM	64QAM

NOTE:

The Hybrid radio capacity and the AM function are available only if the corresponding license files are configured.

Power and ATPC Information

By using the radio network planning software such as the Pathloss, you can analyze and compute the parameters of microwave links and obtain the microwave link power and ATPC information as shown in Table 3.

**Table 3** Power and ATPC information
Parameter	Link 1	Link 2
Transmit power (dBm)	16(NE32) 16(NE33)	20(NE33) 20(NE34)
Receive power (dBm)	-43(NE32) -43(NE33)	-48(NE33) -48(NE34)
ATPC enabling	Disabled	Disabled
Automatic ATPC threshold setting	-	-
Upper threshold of ATPC adjustment (dBm)	-	-
Lower threshold of ATPC adjustment (dBm)	-	-
Maximum transmit power (dBm)	-	-

NOTE:

The transmit power is calculated in AM guaranteed capacity mode.
The receive power is calculated in AM guaranteed capacity mode.
In this example, the ATPC function is disabled.

Information About IF boards

According to the radio type, slot priorities of IF boards, and configuration rules of the 1+1 protection, you can obtain the information about IF boards as provided in Table 4.

**Table 4** Information about IF boards
Parameter	Link 1	Link 2
Main IF board	3-ISU2(NE32) 4-ISU2(NE33)	3-ISU2(NE33) 3-ISU2(NE34)
Standby IF board	5-ISU2(NE32) 6-ISU2(NE33)	-
RF configuration mode	1+1 HSB	1+0
Revertive Mode	Revertive (default value)	-
Enable reverse switching	600s (default value)	-
Enable reverse switching	Disabled	-

NOTE:

It is recommended that you configure the main IF board in the slot with the smaller slot number.
In 1+1 HSB configuration, it is recommended that you disable the reverse switching function. In 1+1 SD configuration, it is recommended that you enable the reverse switching function.
