Page13 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. The separate mounting method is adopted when a double-polarized antenna or big- diameter and single-polarized antenna is used. In this situation, a hybrid coupler can be mounted. That is, two ODUs share one feed boom. Confidential Information of Huawei. No Spreading Without Permission

  16. 16. OptiX RTN 910/950 Hardware Description P-15 Equipment Characteristics (Cont.)  AM Function Based on the Hybrid Microwave 256QAM QPSK 16QAM 64QAM 128QAM 256QAM Channel Capability E1 Services Ethernet Services Copyright © 2009 Huawei Technologies Co., Ltd. All rights reserved. Page15 Adaptive modulation (AM) is a technology wherein the modulation mode can be adjusted automatically according to the channel quality. In the case of the same channel spacing, the microwave service bandwidth varies according to the modulation mode. The higher the modulation efficiency, the higher the bandwidth of the transmitted services. When the channel quality is favorable (such as on days when the weather is favorable), the equipment adopts a higher modulation mode to try to transmit more user services. In this manner, the transmission efficiency and the spectrum utilization of the system are improved. When the channel quality is degraded (such as on days when the weather is stormy and foggy), the equipment adopts a lower modulation mode to transmit only the services with a higher priority within the available bandwidth and to discard the services with a lower priority. In this manner, the anti-interference capability of a link is improved and the link availability of the services with a higher priority is ensured. When the hybrid microwave equipment adopts the AM technology, it controls service transmission based on the service bandwidth and QoS policy corresponding to the current modulation mode. The E1 services have the highest priority. By adopting the CoS technology, the equipment schedules Ethernet services of different types to the queues with different priorities. The services in the queues of different priorities are transmitted to the microwave port. When the queues of certain priorities are congested because of insufficient microwave bandwidth, the queues of these priorities discard certain or all services. When the hybrid microwave works in the lowest modulation mode, the equipment transmits only the E1 services and the Ethernet services of the high priority on the available bandwidth. When the Hybrid microwave works in any other modulation mode, all the additional bandwidth is used to transmit the Ethernet services. In this manner, the availability of the links that carry the E1 services and the Ethernet services of the high priority is ensured and the Ethernet service capacity is increased, thus providing the dynamic bandwidth. Slide shows the service change caused by the AM. The orange part indicates the E1 services. The blue part indicates the Ethernet services. The closer to the edge of the blue part, the lower the priority of the Ethernet service. Under all channel conditions, the E1 services occupy the specific bandwidth that is permanently available. Thus, the availability of the E1 services is ensured. The bandwidth for the Ethernet services varies according to the channel conditions. When the channel is in bad conditions, the Ethernet services of the low priority are discarded.
