0.1. Safety Instructions
Before installing and operating the IDAS, read and comply with the following safety instructions:
1. Engineering design: The IDAS achieves signal amplification of the uplink and downlink through direct coupling
of the 2G, 3G and LTE signals from the base station. The expansion unit accesses WLAN signals and combines
the WLAN signal with the coupled signal for indoor coverage. Normal use of the system will not damage the
base station; however, with the increase of RU during network coverage for indoor distribution, the uplink
output noise level may affect the sensitivity of the base station, which should be considered during
engineering design.
2. Grounding: the shells of the access and expansion units of the device have protective ground terminals. During
installation, connect the ground terminals securely to the protective building ground with yellow and green
conductors or with braided ground wire. The aerial and feeder must be adequately grounded.
3. Power supply: The power source must be within the required range of the device. The rated voltage range for
the AC power supply system is AC100V～240V and the rated frequency range is 50Hz / 60Hz. The rated
power of the AU, EU and RU is 100W, 50W and 250W, respectively. The ground terminal of the three-core
power socket used at the device installation site must be securely connected to the protective building
ground.
4. Electric shock prevention: touching the internal power supply units is dangerous. To prevent electric shock, do
not perform live-line work.
5. The optical module can support a hot plug, but do not turn the optical fibre head towards any human body
part when plugging it in.
6. During device configuration, upgrading and plugging in units and parts, first disconnect the standby lithium
battery and device power source.
7. When accessing the radio-frequency signal, confirm that the downlink signal is no greater than 10dBm,
otherwise the device will not operate normally and damage may occur to the circuit.
CrossFire – A revolution in RF Transport for In Building Wireless

1. System Overview
1.1. Overview
The IDAS system includes the Access Unit (AU), Expansion Unit (EU) and Remote Unit (RU).
Using digital processing and digital optical transmission technology, the AU frames radio-frequency signals from base
stations of different operators, and of different standards and frequency bands, and transmits the composite signal to
the EU via optical fiber. WLAN and small cell base station signals access the gigabit/megabit Ethernet port on the EU and
are reframed with optical signals from the AU and then transmitted to the RU via optical fiber. The RU conducts
digital-analog conversion and power amplification of the input signals and then achieves radio coverage through the
antenna-feeder system for signals of all standards and frequency bands via 50Ohm coaxial cable.
1.2. Operating Fundamentals

WARNING: The design of the antenna installation needs to be implemented in such a way so as to ensure RF
radiation safety levels and non-environmental pollution during operation.
1.3. Technical Specifications
See the Technical Specifications Document for details.
1.4. System Framework
Figure 1-2 shows the typical IDAS system framework.
CrossFire – A revolution in RF Transport for In Building Wireless
User Manual
17 Revision 1.0.1
Figure 1-2 Typical System Framework for the IDAS
1.5. Networking Layout
The IDAS has a number of different networking layouts shown as Figure 1-3:
The AU supports a star network. Note that the Master-AU can connect to a maximum of two Slave-AUs
simultaneously.
The EU supports a daisy-chained network (for EU—EU) and a star-type network (for EU—RU).
In smaller systems, the AU and RU can be directly connected without the EU, as shown in Figure 1-3.
For a direct AU—RU connection, an RU can cascade up to five RUs at different levels. For an AU—EU—RU
connection, an RU can cascade up to four RUs at different levels.

2. Operations and Maintenance Terminal
2.1. Introduction to the OMT
The Operations and Maintenance Terminal (OMT) software runs on all of the devices in the iDAS system. The
interface to the OMT is WebOMT. WebOMT is based on a web browser and is compatible with most common browsers
such as IE and Google Chrome. WebOMT is customized for the IDAS and is used for query, debugging and configuration.
An NMS can only connect to the Master AU, therefore the Master AU is known as the host. However, to maintain the
IDAS system locally, a technician can access the whole system through any one of the devices in the IDAS system (Master
or Slave AU, EU or RU). For example, the technician may connect a laptop to the RU, log into the WebOMT and query the
DAS topology. The device name on the topology diagram is a URL link to the WebOMT on the selected device. Therefore,
by clicking on the device’s name, the technician can access any other device easily, regardless of which device’s WebOMT
they initially logged into.
2.2. Accessing the OMT
There are several methods for accessing the OMT:
Wired access
Wireless access
USB access
Unless indicated otherwise, the examples use the Windows XP operating system and Internet Explorer 8 web
browser.
2.2.1. Wired Access to the OMT on the Master AU
In the IDAS system, the Master AU is defined as the host, with the other AUs, EUs and RUs defined as slaves. See
Section 3.6 for Master/Slave AU selection.
The default IP address of the AU is 10.7.3.200, while the slaves have no fixed IP address. The IP addresses of the
slaves are assigned by the host automatically, based on the network topology.
To set up wired access to the OMT, use the following procedure:
1. Connect a PC to the CONSOLE port on the front panel of the Master AU with a network cable.
2. Change the TCP/IP properties (see Figure 2-1):

Single Optical Fibre-module
Figure 6-13 shows that when using a pair of single optical fibre-modules, the wavelength of the two modules
should be different, for example, 1271nm & 1331nm. See Table 51 for the optical fibre module corresponding to each
port. When the optical module is unplugged or not synchronized, the indicators are red as shown in the left pair of
indicators in Figure 6-15. Check whether both indicators turn green after connecting one pair of optical modules. If they
are red, the terminal has not synchronized. See Section 9 for how to resolve this issue.

Double Optical Fibre-module
The optical connector unit includes an optical module and optical fibre. Figure 6-14 shows that when using a double
optical fibre-module, the optical transmitter and optical receiver should correspond to each other. In other words, the
optical transmitter of optical module A should correspond to the optical receiver of optical module B and the receiver of
A should correspond to the transmitter of B. The optical receiver and transmitter terminals of the optical module can be
determined by the triangular mark on the optical module. Figure 6-14 shows the triangular mark in the yellow box and
the red and green lines indicate the optical fibre connections.
Figure 6-14 Optical Module Connection
Each pair (2) of optical module cages has four LED indicator arrows. The two on the left are green and the two on the
right are red as shown in Figure 6-15. The indicator arrows represent the synchronization status of the upper and lower
optical modules. When optical module A has synchronized with module B (both uplink and downlink), the indicators turn
green as shown in the right pair of indicators in Figure 6-15. When the optical module is unplugged or not synchronized,
the indicators are red as shown in the left pair of indicators in Figure 6-15. Check whether both indicators turn green
after connecting one pair of optical modules. If they are red, the terminal has not synchronized.

User Manual
73 Revision 1.0.1
Figure 6-15 Optical SYNC Status
6.4.2. AU connections
Prior to attempting the AU connections, read Section 3 thoroughly.
The AU has eight optical ports, designated by eight silk-screened images: “AU1”, “AU2”, “OP1/AU”, “OP2”, “OP3”,
“OP4”, “OP5”, “OP6”. The ports “OP1~OP6” all have the same functionality, providing connections to lower level EUs or
RUs. Insert the optical module into any one of the OP1～OP6 ports, then insert the tail of the optical fibre into the
optical module and connect the other end to the lower EU or RU. After the AU and EU/RU are connected and powered
on, the optical interface indicator LED will turn green, which indicates that the devices are synchronized. If the optical
indicator LED does not turn green, check whether the connection direction of the optical fibre is correct and whether the
optical module is inserted tightly.
The “AU1” and “AU2” optical ports are for connecting to the slave AU.
When connecting to the slave AU, first access the slave AU independently (see Section 2.2 for instructions on how to
access the WebOMT for the Slave AU). Ensure the status of the AU is “Slave AU” and then connect the optical fibre.
Note: The connection between the Master AU and the Slave AU can only be from the OP1/AU port on the Slave AU
to the AU1 (or AU2) port on the Master AU; other optical ports are invalid for Master-Slave AU connections.
CrossFire – A revolution in RF Transport for In Building Wireless
User Manual
74 Revision 1.0.1
6.4.3. EU connections
Prior to attempting the EU connections, read Section 4 thoroughly.
The EU has 8 optical ports and 6 electrical ports. The optical “SLAVE” port should be connected to the AU or upper
EU and the optical “MASTER” port should be connected in a cascading manner to a lower EU in a daisy chain. (Refer to
the networking definition of a daisy chain.) The OP1~OP6 ports have the same functionality and are all used for
connections to RUs. After the EU is connected to the upper device and powered on, the optical indicator LED turns green
which means that the devices are synchronized. If the LED does not turn green, see Section 9 to resolve the issue.
Each EU has six electrical ports, GE1~GE6, which support six LAN signals. Each electrical port corresponds to a
specific optical port, for example, port GE1 corresponds to port OP1 and port GE6 corresponds to port OP6.
6.4.4. RU connections
Prior to attempting the RU connections, read Section 5 thoroughly.
The RU has 2 optical ports, “SLAVE” and “Master. The “SLAVE” port should be connected to an upper AU, EU or RU,
and the “MASTER” port should only be connected to a lower RU. After the RU has been connected to the upper device
and powered on, the optical indicator LED turns green which means that the devices are synchronized. If the LED does
not turn green, see Section 9 to resolve the issue.
6.4.5. Standby battery connection
A plug is connected to a power source on the output wire of the device’s lithium battery. To prevent battery
discharge, this is unplugged before shipping. After the device is operational, plug it in to ensure normal reporting if the
power is cut.
6.5. WLAN Access (Wi-Fi)
Each EU has six electrical ports, GE1~GE6, which support up to 6 LAN signals. LAN signals are input on the GE1~GE6
ports and output from the corresponding OP1~OP6 ports. The signals are then transmitted to the RUs via optical signals
over optical fibre and output from the GE port on the RU. Each RU connects to an AP device through their respective GE
port. Thus, 6 independent Gigabit Ethernet transmission channels can be completed. See Figure 6-16 for WLAN connection
details.
Note: each electrical port (GE1~GE6) must correspond to an optical port (OP1~OP6), i.e. GE1 should correspond to
OP1, GE2 should correspond to OP2, etc. WLAN signal input on GE1 is then sent out on OP1.
If there are multiple access points (AP) that are connected to more than one cascading RU in a signal chain, the WLAN
CrossFire – A revolution in RF Transport for In Building Wireless
User Manual
75 Revision 1.0.1
signal will only be output from one of the RUs, with the priority being RU1>RU2>RU3 when selecting which RU the signal
will be output from. If there is only one AP device, then the WLAN signal is always output from the RU that is connected to
the AP.

The site number must be set using the WebOMT on the Master AU before connecting to the network management
system (NMS). The NMS should identify devices by their unique site number. Network parameters also need to be set up
for the specific network. If the NMS supports the SNMP protocol, set Protocol Select to “SNMP” and configure related
parameters such as the Trap IP Addr, Trap Port, Subnet Mask, Default Gateway, etc. as shown in Table 7. If the NMS
supports the ZENIC8 proprietary protocol, set Protocol Select to “TCP/IP” and configure the corresponding parameters
as shown in Table 6.
The remote FTP server parameters also need to be set up if remote software upgrades are supported. These
parameters are set in the Engineering tab ―> User Para sub-tab in the WebOMT. See Figure 7-3 for details.

7.3. Channel Gain Adjustment
After setting the channel properties, access the RF signals. In the IDAS, the nominal downlink input power of the AU
is 0dBm and the maximum allowable input power is 15dBm. Therefore, before accessing the RF signals, estimate the
signal power. Monitor the downlink input power with a spectrum analyser or read the downlink input power value from
the “Combiners” on the WebOMT in order to set the downlink input power within the appropriate range.
To adjust gain on AU WebOMT (see Figure 7-5):
1) In the AU WebOMT, select the Engineering tab.
2) Select the Combiners sub-tab on the Engineering page.
3) Check the input power value of the port which there is input signals. See Figure 3-4 for active combiner ports.
4) Set the attenuation value. For example, the input power value of port 1 channel 1 is 3.499 dBm, then enters
3.50 attenuation in port 1 Attenuation value and click set to confirm.

7.4. Alarm Parameters Setup
After completing the radio-frequency channel properties configuration, set up the alarm parameters using the
following procedure:
1. In the WebOMT, select the Engineering tab.
2. Set the statuses of the optical transceiver one by one.
3. If there is an optical path connection, enable the basic device alarms, such as Power Interruption Alarm,
Battery Failure Alarm, MOV Alarm, etc. For alarms related to channel properties, such as the DPLL unlocked
Alarm, LO unlocked Alarm, OP transceiver failure Alarm, etc., only enable those associated with the channels
which have an input signal, to avoid unnecessary alarms. See Figure 7-8 for details.
Wait 3~5 minutes after completing the setup, then query to see if there is a failure alarm for the device. If there is
an alarm, see Section 9 or troubleshooting manual to resolve the issue. Figure 7-8 shows an example of AU Alarm
Parameters Setup.

8. Software Upgrade
The Master AU consolidates the management of software upgrades for the entire system and saves the last software
package for the AU, EU and RU. Slave devices compare the local software with that saved in the Master AU at run time. If
the software version is different, the slave device will start the software upgrade progress and reset automatically after
the upgrade is complete. The benefit of this approach is that if a slave device is replaced, a software upgrade is started
automatically without having to do additional operations. If the Master AU is replaced, before connecting the new
Master AU to the system, check the software version using the WebOMT as shown in Figure 8-1. If the software version
is not the latest version, upload the latest software packages to the new Master AU.
Figure 8-1 Checking Software Package Version
As mentioned above, the system software upgrade is divided into two steps. First, upload the package to the master
AU. Second, the slave device automatically downloads the new software package from the Master AU to complete the
upgrade process. This process can be performed in one of two ways: by performing a local upgrade using the OMT or by
performing a remote upgrade via FTP.
8.1. Local Upgrade
As an example, to do an RU or EU upgrade:
1. Log in to the WebOMT on the Master AU. Click the Upgrading button on the main page to navigate to the
software upgrade page. See Figure 8-2.
CrossFire – A revolution in RF Transport for In Building Wireless
User Manual
89 Revision 1.0.1
Figure 8-2 Software Upgrade Step 1
2. On the software upgrade page, as shown in Figure 8-3, click the Upload button to upload the RU or EU
software package file.
Figure 8-3 Software Upgrade Step 2
3. When the software upload has completed successfully, select the file that was just uploaded and click the
Upgrade button to complete the software upgrade, as shown in Figure 8-4 for an RU upgrade.
Figure 8-4 Software Upgrade Step 3
4. When the upgrade has completed, confirm that the software has been updated correctly as shown in Figure
8-1.
There is one difference in the AU upgrade process. Follow the same steps as for the RU or EU; however, when the AU
package upgrade has completed successfully, the Master AU resets itself automatically to complete the software

upgrade.
8.2. Remote Upgrade
Use FTP to perform an upgrade remotely. As shown in Figure 8-5, set up the FTP server IP address, port number,
login name, login password, file storage path and filename to be upgraded. Then, set the FTP File Transfer Control item
to “Start upgrade”. To complete the upgrade, click the Set button to download the software from the FTP server. When
using this method, ensure that the FTP server is running correctly and the file to be upgraded has been saved in the
specified directory.

9. Device Maintenance
9.1. Regular Maintenance
When the IDAS is running, regular inspection is recommended, as follows:
1. Check that RF and power cables are connected securely and that all screws are tight. If any connections pose a
safety hazard, deal with them as soon as possible.
2. Check the ground status of the device.
3. Measure the power supply voltage of the devices.
4. Check the operating status and main performance parameters of devices regularly through the NMS or OMT.
5. Check whether all warning marks are intact.
If a fault occurs and the device cannot operate normally, return the device to the factory for repair or send to
technicians for site repair.
9.2. Troubleshooting
This section lists problems that may arise in engineering applications and suggests relevant solutions.
1. The slave device cannot synchronize with the master device:
a) Query the software version using the OMT. Make sure that the device is running the correct software.
b) Check the SFP module to confirm whether the SFP module has been damaged.
c) Restart the device. If the problem persists, the device may have been damaged. The equipment needs to
be replaced.
2. RU downlink shows an output-power alarm:
a) The gain of the RU downlink is equal to (37- DL attenuation dB). Check the RU downlink baseband power,
and then add the downlink baseband power to the RU downlink gain. The result should be close to the
output power. If the deviation is more than 5 dB, the PA module may be damaged.
3. Over-temperature alarm:
a) The devices need space to dissipate heat. Ensure the device is not covered by anything. If the device is
covered, the temperature will rise.

10. Application Scenarios
This section describes various configuration scenarios for the IDAS.
10.1. Operators Located at Same Site
In this example, operators A, B, C, D and E are located at the same site (see Figure 10-1). Operators B and C operate
in the same frequency band, which can be combined in one channel in “the RF domain”. The maximum bandwidth per
operating band should be less than 60MHz and the maximum bandwidth of all operators should be less than 200 MHz.

10.2. Operators Located at Separate Sites
In this example, operators A, B, D and E are located at one site and operators C and F are located at a different site.
(See Figure 10-2) Operators C and F can access the Master AU through the Slave AU so that all operators can combine
within the same fibre from the Master AU to the EU. In contrast with the scenario in section 10.1, operators B and C can
be combined in the “baseband domain”. The maximum bandwidth per operating band should be less than 60MHz and
the maximum bandwidth of all operators should be less than 200 MHz.

10.3. MIMO Application
Since the same frequency is used between MIMO1 and MIMO2, operator C, as shown in Figure 10-3, must employ
two special channels in the AU and RU. In order to guarantee coherence between MIMO1 and MIMO2, MIMO1 and
MIMO2 must be in the same AU and RU. The maximum bandwidth per operating band should be less than 60MHz and
the maximum bandwidth of all operators should be less than 200MHz.

In this scenario, RU1 can connect to the EU or directly to the AU. A maximum of four RUs can cascade when RU1 is
connected to the EU and a maximum of five RUs can cascade when RU1 is directly connected to the AU. (See Figure 10-4)
The maximum bandwidth per operating band should be less than 60MHz and the maximum bandwidth of all operators
should be less than 200 MHz.

10.5. WLAN Application
IDAS provides a transparent pipeline for 10M/100M/1000Mbps Ethernet transmission. Each EU has six electrical
ports (GE1~GE6) for six WLAN signals to access. Meanwhile, six optical ports (OP1~OP6) correspond to GE1~GE6 for the
output signal. (See Figure 10-5) The flow path of the signal is:
Input LAN signals— EU— RU— AP— POI— Antenna-feeder system.
Note:
The electrical port must correspond to an optical port, for example, GE1 corresponds to OP1.
If multiple cascading RUs connect, the WLAN signal can be output from a random RU.
If multiple cascading RUs connect and more than one AP device connects to the RUs, the WLAN signal can
be output from one RU, and the priority is RU1＞RU2＞RU3.
