2 Introduction to AISG Device

The Antenna Line Devices (ALDs), used in an antenna system, refer to TMA, RET, TMB,

and accessories. Currently, there are two protocol versions for ALDs: AISG1.1 and

AISG2.0.

AISG1.1: Introduced in 2004, it is designed to enable the RETs (RCUs and their

control devices or software) of different vendors to be interoperable and to achieve

remote control of RCU devices.

AISG2.0: Developed based on 3GPP standards in 2006, it corrects some errors in

AISG1.1 and supports TMAs in addition to RETs. Besides, it takes into account the

scalability of the protocol itself.

Generally, the AISG devices mainly refer to RETs and TMAs. Sometimes, The RET is

also called RCU or ACU. One RET is mechanically connected to an antenna and controls

the downtilt of the antenna remotely.

2.1 AISG Devices

2.1.1 AISG Ports and Cables on R8882 and RSU82

For the list of AISG cables that have been authenticated by ZTE, refer to A.3.

2.1.1.1 R8882

Figure 2-1 shows the AISG interface on R8882.



Figure 2-1 R8882 AISG Interface

Figure 2-2 illustrates the AISG cable used to connect one R8882 and the RET.

Figure 2-2 Cable for Connecting R8882 and RET

Table 2-1 shows the definition of pins of the AISG interface on one R8882.

Table 2-1 Pins of R8882 AISG Port



2.1.1.2 RSU82

Figure 2-3 shows the AISG interface on RSU82.

Figure 2-3 RSU82 AISG Port

Figure 2-4 illustrates the AISG cable used to connect one RSU82 and the RET.

Figure 2-4 Cable for Connecting RSU82 and RET

Table 2-2 shows the definition of pins of the AISG interface on one RSU82.



Table 2-2 Pins of RSU82 AISG Port

2.1.2 NSBT and ASBT

For the list of NSBTs and ASBTs that have been authenticated by ZTE, refer to 0.

An NSBT is the bias tee used on the eNodeB side and it has two functions:

Providing DC current to an ADTMA or a RET through a feeder.

Modulating the RS485 signals that are used to control the downtilt of the RET or

ADTMA antenna on the eNodeB side into low-frequency analog signals, and

uploading them to the feeder.

Figure 2-5 illustrates one NSBT.

Figure 2-5 NSBT

An ASBT is the bias tee used on the antenna side. It also has two functions:



Providing DC current to a RCU through an AISG cable.

Demodulating the RS485 signals that are used to control the downtilt of the RET or

ADTMA antenna.

Figure 2-6 illustrates one ASBT.

Figure 2-6 ASBT

The difference between an NSBT and an ASBT lies in that the AISG port of the NSBT is a

8-pin male connector, while the AISG port of the ASBT is an 8-pin female connector, as

shown in Figure 2-7.

Figure 2-7 8-pin Male & Female Connectors

2.1.3 ADTMA

An ADTMA acts as two AISG TMAs. It has five ports: Node B0, ANT0, Node B1, ANT1,

and AISG. Figure 2-8 illustrates a typical ADTMA.



Figure 2-8 ADTMA

An ADTMA and a common DTMA are the same in RF performance, the number and

model of RF connectors, and the effect on network performance. However, they are

different in several aspects, as shown in Table 2-3.

Figure 2-9 illustrates the difference between the antenna system with a TMA and that

without a TMA.



Figure 2-9 Antenna System with TMA vs Antenna System without TMA

For the list of TMAs that have been authenticated by ZTE, refer to 0.

2.1.4 RCU (RET)

The RCU is used to adjust the downtilt of an electrically-adjusted antenna. It has an AISG

port, one 8-pin female port, and one 8-pin male port. The 8-pin male port is used to

connect one AISG cable, while the 8-pin female port is used for RCU cascading. Some

antennas have built-in RCUs.



Figure 2-10 RCU (RET)

Prior to the installation of one RCU, read its installation manual carefully because the

installation methods of RCUs of different vendors differ. Incorrect installation may cause

RET calibration to fail. Besides, if the antenna’s downtilt is adjusted manually during RCU

installation, the actual downtilt of the antenna cannot be queried through the RET. As a

result, it is required to perform RET calibration after installation, and if necessary, adjust

the downtilt through the OMC/LMT.

For the list of RETs that have been authenticated by ZTE, refer to A.1.

2.1.5 AISG Port on RET

Figure 2-11 shows the AISG port on a RET.

Figure 2-11 AISG Port on RET

2.2 Application Scenario

Before AISG device commissioning, it is required to connect necessary cables correctly.

For details about the installation of RET antennas, refer to RET Antenna Quick

Installation Guide.



This section describes some common application scenarios of AISG devices. For more

scenarios, refer to FDD LTE Antenna System Solutions and LTE Engineering and

Technical Solutions.

2.2.1 FDD LTE RRU + RET Antenna

2.2.1.1 2T2R

Near End (The distance between the RRU and the antenna does not exceed 20 m)

Normally, in this scenario, the distance between the RRU and the antenna does not

exceed 20 m. For example, both the RRU and the antenna are installed on the top

of a building. Typical configuration of the antenna system includes RET antennas,

RCU, ALPD, and feeders. If the antenna is installed indoors or on the top of a low

building, the ALPD is not necessary. In this case, one AISG cable is used to connect

the antenna and the RRU.

Figure 2-12 shows the connection of the antenna system in the near end scenario.

Here only one sector is illustrated. The connections of three sectors are similar.

Figure 2-12 Antenna System for FDD 2T2R in Near-end Scenario

Far End (The distance between the RRU and the antenna exceeds 20 m)



Normally, in this scenario, the RRU is installed at the bottom of a tower or indoors,

while the antenna is installed on the tower. The distance between the RRU and the

antenna exceeds 20 m. Typical configuration of the antenna system includes RET

antennas, RCU, NSBT, ASBT, and feeders. For the purpose of standardization, the

NSBT and the ASBT should be installed on the main channel of the antenna.

Figure 2-13 shows the connection of the antenna system in the far end scenario.


Figure 2-13 Antenna System for FDD 2T2R in Far-end Scenario



2.2.1.2 2T4R


Figure 2-14 shows the connection of the antenna system in the near end scenario.


Figure 2-14 Antenna System for FDD 2T4R in Near-end Scenario

Far End (The distance between the RRU and the antenna exceeds 20 m)

Figure 2-15 shows the connection of the antenna system in the far end scenario.




Figure 2-15 Antenna System for FDD 2T4R in Far-end Scenario

2.2.2 FDD LTE RRU+RET+ADTMA

In this scenario, the RRU is normally installed at the bottom of a tower, while the RET

antenna and the ADTMA are installed on the tower. The RET is 50 m away from the

RRU.

Typical configuration of the antenna system in this scenario includes RET, RCU, NSBT,

ADTMA, and feeders. The RRU’s ANT port is connected to the feeder through the NSBT,

the RRU’s AISG port is connected to the NSBT with an AISG cable, and the ADTMA’s

AISG port is connected to the RCU with an AISG feeder.



Figure 2-16 shows the connection of the antenna system in the RRU+RET+ADTMA

far-end scenario the case of 2T2R. Here only one sector is illustrated. The connections of

three sectors are similar.

2.2.3 FDD LTE Macro Base Station+RET

When an LTE FDD macro base station is configured with RET antennas, it should

support remote electrical adjustment. For a three-sector macro base station, two

solutions are available:

Solution 1 is illustrated in Figure 2-18, and it is applicable to the case where the

antennas are far away from each other.

2.2.5 Antennas Shared by CDMA and FDD LTE (2T4R)

Suppose three-band (800 MHz, 2.1 GHz, and 2.1 GHz) RET antennas are used, the

connections of the antenna systems should be as follows:

TX0/RX0 and TX1/RX1 of R8882 are connected to the same feeder group.

One RET can be cascaded with another RET with one 0.5 m AISG cable, and it is

not provided with power supply separately. Normally, two AISG cables are provided:

The longer one is used to connect the R8882 with the antenna, while the shorter

one is for cascading.

The existing feeders keep unchanged.



Tip:

If the existing cable for CDMA RET is with an AISG 2.0 connector, it can be reserved for

use.

If the existing cable for CDMA RET is without a standard AISG 2.0 connector, it is

recommended that the CDMA RET be remotely controlled by the EMS by means of RSU

cascading.

If the RSUs are not cascaded, the compatibility and performance issues of the existing

3.1.2 Creating Antenna Entity Objects

Purpose

The purpose of the operations here is to create antenna entity objects.

Procedure

To create antenna entity objects, perform the following steps:




2. In the Managed Element pane, double-click Antenna Entity Object (path:

Managed Element --> Device ---> BTS Auxiliary Peripheral Device --> Antenna

Service --> Antenna Entity Object) to open the Antenna Entity Object-List tab

page on the right.

Entity Object tab page.



Figure 3-5 Antenna Entity Object Tab Page

4. In the Antenna Entity Object tab page, set the parameters according to the

descriptions in Table 3-2.

Tip:

Normally, one RET corresponds to one antenna entity object. However, the number of

objects should be configured based on the application scenarios. For example, in the 2T4R

scenario, as one RRU/RSU uses one four-port antenna and this antenna is installed with two

RETs, two antenna entity objects should be created.

5. Click the icon to create one antenna entity object.

Figure 3-6 shows the configuration of one antenna entity object.



Figure 3-6 One Antenna Entity Object Being Configured

6. Repeat steps 3 – 5 to create other antenna entity objects.


In practice, as it is difficult for the OMC engineer to obtain the antenna information, the

antenna entity objects are, by default, configured on the principle of two RETs per cell. As

a result, for a three-cell 2T2R scenario, six antenna entity objects may be configured in

the OMC, but in reality, only three objects (AntEntity=1/3/5) are used and associated with

RETs, and the other three objects are reserved. If 2T2R is to be upgraded to be 2T4R, no

objects need to be configured. Just associate the reserved antenna entity objects with the

new RETs.

Table 3-3 Antenna Entity Object Configuration

Example

Suppose the site scenario of one eNodeB is 2T4R, as described in Section 2.2.1.2. Six

antenna entity objects should be configured for the eNodeB and their numbers are 1, 2, 3,

4, 5, and 6 respectively, their Used antenna attribute is AntProfile=1, and RET device

type is Uni-antenna RET. Among these objects, objects 1 and 2 correspond to the two

RETs of the first antenna; objects 3 and 4 correspond to the two RETs of the second

antenna, and objects 5 and 6 correspond to the two RETs of the third antenna.

Upon configuration, the Antenna Entity Object-List tab page looks like Figure 3-7.

Figure 3-7 Antenna Entity Object Configuration Example


As to the selection of used antenna attributes, follow the principles below:

Dual-polarized smart antenna (eight channels): AntProfile=16

Dual-polarized smart antenna (two channels): AntProfile=20



Distributed antenna (single channel): AntProfile=201

Smart antenna of common linear array (eight channels): AntProfile=12

Smart antenna of common linear array (four channels): AntProfile=10

Distributed antenna (two channels): AntProfile=202

3.1.4 Configuring AISG Power Outlets

For some RRUs/RSUs (e.g. R8882/RSU82), their AISG power outlets are closed

disabled by default. In this case, the AISG devices cannot be scanned. As a result, it is

required to configure their power outlets to provide power supply to the AISG devices.

Note:

For RRUs such as R8884, there is not the PowerOutlet Set option the EMS and it is not

necessary to configure the AISG power outlet parameter. In this case, ignore the operations

in this section.

Purpose

The purpose of the operations here is to configure AISG power outlets to provide power

supply to the AISG devices.

Prerequisite

Before configuring the AISG power outlets, ensure the RRUs/RSUs device have been

configured.

Meanwhile, it is required to check the link connection. The connection should not be

short-circuited or open-circuited; otherwise, even after the AISG power outlet is

configured, the power is cut off due to overcurrent protection.

in 2T2R S111 scenario), the configuration of RF cables can be done with the following

steps:

Tip:

If no RET connects to one ADTMA, this ADTMA should be configured with two RF cable

records as each ADTMA includes two units, which connect to two RF ports of one

RRU/RSU respectively.

If there is one RET connecting to one ADTMA, this ADTMA should be configured with

three RF cable records: two records are used for connections between two ADTMA units and



two RRU/RSU RF ports, and the other is used for connection between the ADTMA and the

RET.

3.2.3 Adding TMA

Before AISG device scanning, no record is in the AISG Device-List of an RRU or RSU.

This section describes how to configure the TMAs.

Purpose

The purpose of the operations here is to scan AISG devices and add them.

Procedure

The configuration of RETs falls into two main steps: scanning AISG devices and creating

TMAs, as described in Section 3.2.3.1 and Section 3.2.3.2 respectively.

3.2.3.1 Scanning AISG Devices

Refer to the description in Section 3.1.5.1 to scan AISG devices. The scanning result

may look like Figure 3-46.



Figure 3-46 Viewing Details of Scanning Result

Tip:

For each ADTMA, two units are scanned.

3.2.3.2 Creating TMAs

1. In the Details pane of the scanning result, select the detailed record, and click the

icon to display the Create AISG Device dialog box.

2. In the Create AISG Device dialog box, select a proper TMA device for the

Connected TMA device, and click OK.

3. After the AISG device is added, its information is displayed in the Configuration

Management.

To view the AISG device information, open the AISG Device-List tab page by

double-clicking AISG Device in the Managed Element pane (path: Managed

Element --> Device ---> RRU/RSU --> R8882/RSU82 --> AISG Device).

4. Repeat steps 1 - 4 to add AISG devices for other RRUs.

3.2.4 Synchronizing AISG Data

After the TMA devices are added, perform incremental synchronization of AISG data,

ensuring the data on the RRU to be consistent with those in the EMS. For details about

the synchronization operations, refer to Section 3.1.6.

3.2.5 Performing TMA-Related Operations

After data synchronization, TMA-related operations can be performed, such as “Set

mode”, “Query mode”, and “Query gain”.

4 FAQ

4.1 Why to Send Configuration Data

ZTE’s LTE eNodeBs support RETs of many brands, and the RETs of one brand can only

work with the antennas of the same brand. As a result, it is necessary to send the

configuration data of the RET.

The configuration data include the parameters of the connected antenna, such as

maximum downtilt and minimum downtilt.

In sending the configuration data, make sure the correct configuration data file is used.

For the RETs of some vendors, the alarm “RET not calibrated” may be raised after the

configuration data are sent. In this case, it is required to calibrate the RET after

configuration data sending.

4.2 Why to Calibrate the RET

RET calibration is to calibrate the RET by running the antenna for a cycle. After

calibration, the RET can be used to set the downtilt of the antenna so as to ensure the

accuracy and precision of the downtilt.

For RETs of some vendors, they cannot be used to adjust the downtilt if the calibration

operation is not performed. After calibration, the antennas of some vendors are at the



minimum downtilt, while the antennas of other vendors are at the downtilt before

calibration.

Generally, a newly-installed RET must be calibrated before it is used to adjust the

downtilt.

4.3 When to Calibrate the RET Downtilt

RET calibration must be performed in one of the following cases:

The AISG device is scanned for the first time and the downtilt is set.

The configuration data of one RET is changed.

An RET is replaced with a new one.

A calibration failure alarm is raised, and the downtilt has to be adjusted. If the

downtilt is not required to be adjusted, such an alarm can be ignored because it has

no impact on the services.

4.4 What to Be Paid Attention to in RET Calibration

Before RET calibration, ensure the RET and the antenna are correctly installed.

Otherwise, RET blocking may take place during RET calibration and the RET may raise

eNodeB-related alarms.

Besides, after calibration, the antenna may be at the minimum downtilt or the downtilt

before calibration, so record the downtilt of the antenna before calibration.

4.5 How to Handle the Alarm “Gain Setting Failure”

of a TMA

If a TMA has a fixed gain, this TMA does not support gain setting operations. When the

TMA’s gain is set to a value other than the fixed gain, the alarm “gain setting failure” is

raised.

If a TMA has not a fixed gain, the alarm “gain setting failure” is also raised when the value

of the gain exceeds the gain range supported by the TMA.

Once such an alarm is raised, re-set the gain to a value that is supported by the TMA.

Currently, the gain of commonly-used TMAs is 12 dB, which should be set to be 48 * 0.25

(where 0.25 is the resolution) in the EMS. If the alarm does not disappear after the gain is

set to a correct value, use the alarm clearing command to clear it.



AppA Antenna Products Authenticated by ZTE

A.1 RETs

For RETs purchased from vendors, interoperability test (IOT) should be conducted with

ZTE’s base station devices. Once one RET passes the IOT, it is authenticated by ZTE.

In principle, all standard AISG1.1 and AISG2.0 RETs can operate with ZTE’s devices.

Currently, AISG2.0 RETs are configured. In a swapping or update project where there

are AISG1.1 RETs used at the site, the onsite engineers must conduct the IOTs between

these RETs and ZTE devices before deciding whether the existing AISG2.0 RETs are

reserved for use.

AppTable A-1 lists the RETs that have been authenticated by ZTE.

Tip:

1. One RET can only work with the antennas of the same vendor.

2. AISG1.1 RETs and AISG 2.0 RETs are the same in appearance and cost. They differ in

the respective of software and model.

A.2 TMAs and Bias Tees

Normally, the AISG2.0 TMAs should be configured. AISG1.1 TMAs or common TMAs are

configured in some special scenarios or in the case the old TMAs are used.
