In this solution, the regional backhaul network is not necessary because the OptiX RTN 980 can be
directly connected to the RNC and BSC. The OptiX RTN 980 supports PWE3 emulation so that TDM services and IMA E1 services can be
backhauled on the packet switching networks.
1.2 Benefits
Integrated IP Radio with High Bandwidth and High Efficiency The OptiX RTN 980 provides an integrated IP radio transmission system that transmits Hybrid and Packet services with high bandwidth and high efficiency.
The air interfaces provide channel bandwidth from 7 MHz to 56 MHz and support AM modes from QPSK to 256 QAM.
The integrated IP radio is capable of transmitting any or all of the following three types of services: Native E1/STM-1, Native Ethernet, and packet services encapsulated through PWE3. The types of services can be configured by using software. Therefore, the OptiX RTN 980 supports a smooth upgrade from the Hybrid radio to the Packet radio.

Figure 2-1 IDU 980
ODU The ODU is the outdoor unit of the OptiX RTN 900. It performs frequency conversion and amplification of signals.
The ODU is shared by the OptiX RTN product series. The OptiX RTN 900 product series share a set of ODUs. The OptiX RTN 980 supports standard-power ODUs and high-power ODUs.
There are two methods of mounting the ODU and the antenna: direct mounting and separate mounting.
The direct mounting method is normally adopted when a small-diameter and single-polarized antenna is used. In this situation, if one ODU is configured for one antenna, the ODU is directly mounted at the back of the antenna. If two ODUs are configured for one antenna, an RF signal combiner/splitter (hereinafter referred to as a hybrid coupler) must be mounted to connect the ODUs to the antenna.
Figure 2-2 shows the direct mounting method.

Figure 2-2 Direct mounting
The separate mounting method is adopted when a double-polarized antenna or big-diameter and single-polarized antenna is used. Figure 2-3 shows the separate method. In this situation, a hybrid coupler can be mounted. That is, two ODUs share one feed boom.
Figure 2-3 Separate mounting
The OptiX RTN 910 provides an entire frequency band antenna solution, and supports the single-polarized antenna and dual-polarized antenna with a diameter of 0.3 m to 3.7 m and the corresponding feeder system.
