Software Programmable Radio The IDU 605 supports the software programmable radio (SPR) function, which means that you can set the microwave capacity by using the software.

Automatic Transmit Power Control The automatic transmit power control (ATPC) function enables the output power of the transmitter to automatically trace the level fluctuation at the receive end. This reduces the interference with neighboring systems and residual BER.

ACM-Based Hybrid/Ethernet Microwave System The Adaptive Code Modulation (ACM) technology is used to adaptively adjust the coding and modulation schemes according to the quality of the channel. When the channel is in good conditions (for example, on a sunny day), the equipment adopts the high-efficiency modulation scheme and low-gain coding scheme to ensure that a maximum user services are transmitted, thus improving the transmission efficiency and the frequency spectrum utilization. When the channel is in bad conditions (for example, in stormy or foggy weather conditions), the equipment adopts the low-efficiency modulation scheme and high-gain coding scheme. In this case, only the


Product Description


high-priority services are transmitted to enhance the anti-interference capability of the link, thus ensuring the availability of the link of the high-priority services.

The ACM technology can adopt the QPSK/16QAM/32QAM/64QAM/128QAM/256QAM as the modulation mode. When the ACM is used to switch the coding and modulation schemes, the low-priority services are discarded, and bit errors or bit sliding does not occur in high-priority services. The scheme switching speed meets the requirement against the 100 dB/s fast fading.

In the ACM-based hybrid microwave system, the E1 services have the highest priority and the Ethernet services are classified into multiple traffic flows with different priority levels according to a quality of service (QoS) technology, for example, the class of service (CoS) technology.

When the hybrid microwave system adopts the low-efficiency modulation scheme, the equipment transmits only the E1 services (if the service bandwidth is larger than the E1 service bandwidth, extra Ethernet services with the highest priority can be transmitted).

When the hybrid microwave system does not adopt the low-efficiency modulation scheme, the added bandwidth is used to transmit the Ethernet services. Hence, the availability of the link is ensured for the E1 services and high-priority Ethernet services, and the Ethernet service capacity is expanded.

Figure 2-1 illustrates the transmission mode in the hybrid microwave system. The orange part indicates the E1 services whereas the light blue part indicates the Ethernet services. In the light blue part, the priority of the Ethernet services lowers from the inner part to the edge.

In all kinds of channel conditions, the E1 services are allocated with an available bandwidth. The bandwidth of the Ethernet services varies according to the channel conditions. When the channel is in bad conditions, the low-priority Ethernet services are discarded.

Synchronous Ethernet The synchronous Ethernet is a technology used to synchronize the clock frequencies at the Ethernet physical layer, and thus is similar to the SDH clock.

The synchronous Ethernet extracts the clock from the serial code stream on the Ethernet line and uses the clock to transmit data, thus implementing the transfer of the clock.

The equipment that adopts the synchronous Ethernet technology extracts the clock from the Ethernet line connected to the BSC/RNC, and then transmits the clock signal through the microwave to the next hop equipment. The next hop equipment transmits the clock signal through the Ethernet interface to the BTS/Node B. Then, the BSC/RNC and BTS/Node B are synchronized.

ACM-Based Hybrid/Ethernet Microwave System The automatic code modulation (ACM) technology is used to automatically adjust the coding and modulation schemes according to the quality of the channel. When the


Product Description


channel is in good conditions (for example, on a sunny day), the equipment adopts the high-efficiency modulation scheme and low-gain coding scheme to ensure that a maximum user services are transmitted, thus improving the transmission efficiency and the frequency spectrum utilization. When the channel is in bad conditions (for example, in stormy or foggy weather conditions), the equipment adopts the low-efficiency modulation scheme and high-gain coding scheme. In this case, only the high-priority services are transmitted to enhance the anti-interference capability of the link, thus ensuring the availability of the link of the high-priority services.

The ACM technology can adopt the QPSK/16QAM/32QAM/64QAM/128QAM/256QAM as the modulation mode. When the ACM is used to switch the coding and modulation schemes, the low-priority services are discarded, and bit errors or bit sliding does not occur in the high-priority services. The scheme switching speed meets the requirement against the 100 dB/s fast fading.

In the ACM-based hybrid microwave system, the E1 services have the highest priority and the Ethernet services are classified into multiple traffic flows with different priority levels according to a quality of service (QoS) technology, for example, the class of service (CoS) technology.

When the hybrid microwave system adopts the lowest-efficiency modulation scheme, the equipment transmits only the E1 services (if the service bandwidth is larger than the E1 service bandwidth, extra Ethernet services with the highest priority can be transmitted).

When the hybrid microwave system does not adopt the lowest-efficiency modulation scheme, the added bandwidth is used to transmit the Ethernet services. Hence, the availability of the link is ensured for the E1 services and high-priority Ethernet services, and the Ethernet service capacity is expanded.

Figure 2-1 illustrates the transmission mode in the hybrid microwave system. The orange part indicates the E1 services whereas the light blue part indicates the Ethernet services. In the light blue part, the priority of the Ethernet services lowers from the inner part to the edge.

In all kinds of channel conditions, the E1 services are allocated with an available bandwidth. The bandwidth of the Ethernet services varies according to the channel conditions. When the channel is in bad conditions, the low-priority Ethernet services are discarded.

EthernetServices

The ACM-based Ethernet microwave system is similar to the hybrid microwave system. The only difference is that the bandwidth of the E1 services is occupied by the high-priority Ethernet services in the ACM-based Ethernet microwave system.

Synchronous Ethernet The synchronous Ethernet is a technology used to synchronize the clock frequencies at the Ethernet physical layer, and thus is similar to the SDH clock.

The synchronous Ethernet extracts the clock from the serial code stream on the Ethernet line and uses the clock to transmit data, thus implementing the transfer of the clock.

The equipment that adopts the synchronous Ethernet technology extracts the clock from the Ethernet line connected to the BSC/RNC, and then transmits the clock signal through the microwave to the next hop equipment. The next hop equipment transmits the clock signal through the Ethernet interface to the BTS/Node B. Then, the BSC/RNC and BTS/Node B are synchronized with each other.

1. The IF signal is amplified in the variable gain amplifier (VGA), so that the loss on the IF cable is compensated for. The VGA also monitors the voltage of the input signal.

2. Through the up-conversion, filtering, and amplification, the IF signal is converted into the RF signal and then sent to the AMP amplifier unit.

3. The AMP amplifies the RF signal (the output power of the signal can be controlled by the IDU software).

4. After the amplification, the RF signal is sent to the antenna through the diplexer.

The O&M uplink signal is a 5.5 MHz ASK-modulated signal and is demodulated in the CTRL control unit.

The –48 V DC power signal is sent to the PWR power unit where the secondary power supply of a different voltage is generated and provided to the modules of the ODU.

Signal Processing in the Receive Direction In the diplexer, the receive RF signal is separated from the antenna signal. The RF signal is amplified in the low noise amplifier (LNA). Through the down-conversion, filtering, and amplification, the RF signal is converted into the 140 MHz IF signal and then sent to the multiplexer.

The O&M downlink signal is modulated under the ASK scheme in the CTRL unit. The 10 MHz signal is generated through the modulation and sent to the multiplexer. The CTRL unit also detects the receive signal level through the RSSI detection circuit and provides the RSSI interface.

The IF signal and the O&M downlink signal are combined in the multiplexer and then sent to the IDU through the IF cable.

For details, refer to section . 7 "Network Management System”.


Product Description


5.3 NE Software The NE software manages, monitors, and controls the running status of an NE. Through the NE software, the NMS communicates with the boards, and control and manage the NE.

The IDU 610 and IDU 620 use the same set of NE software, and the IDU 605 uses another set of NE software. The two sets of NE software are based on the same software platform and contain the software modules including the real time multiple task operating system module, network side (NS) software module, equipment management software module, and database management software module.

5.4 Board Software The board software manages and controls the running status of the ODU and all the boards except for the SCC of the IDU.

The IDU 610 and IDU 620 use the same set of board software. Particularly, only the EMS6 board has independent board software, which runs in the CPU of the EMS6 board. The software of other boards, in the form of modules, is integrated with the NE software and runs in the CPU of the SCC board.

The IDU 605 has no independent board software. The board software of the IDU 605, in the form of modules, is integrated with the NE software and runs in the CPU of the SCC board. The IDU 605 1A, IDU 605 1B, IDU 605 2B share one set of software whereas the IDU 605 1F and IDU 605 2F share the other set of software.

The ODU is considered as a logical board. The board software of the ODU that runs on the SCC board manages the ODU through the O&M channel between the IDU and the ODU.

6 Networking

6.1 IDU 605 Networking 6.1.1 Point-to-Point Networking

In this networking mode, the services between two nodes are transported over microwave.

In a point-to-point network, you can use the IDU 605 1A or IDU 605 1B that provides 1+0 non-protection configuration for the microwave services, or you can use the IDU 605 2B that provides 1+1 protection configuration for the microwave services.

Figure 6-1 Point-to-point networking

OptiX RTN 600(IDU 605)


In a point-to-point network, you can replace the IDU 605 with the IDU 610 or IDU 620 if the IDU 605 cannot meet the requirements of the microwave link attributes or service interfaces.

6.1.2 Terminal Stations in a Radio Transmission Network Services can be transmitted between the NE that uses the IDU 605 and the NE that uses the IDU 620 through microwave. Therefore, the NE that uses the IDU 605 can function as the terminal station of a radio transmission network and construct the last hop together with the NE that uses the IDU 620.
