Network Position The OptiX RTN 900 is a new generation split microwave transmission system developed by Huawei. Itcan provide a seamless microwave transmission solution for a mobile communication network orprivate network. The OptiX RTN 900 products are available in two types: OptiX RTN 910 and OptiX RTN 950. The IDUof the OptiX RTN 910 is 1U high and supports one or two IF boards. The IDU of the OptiX RTN 950 is2U high and supports one to six IF boards. The users can choose an appropriate type based on theactual requirements. The OptiX RTN 900 provides several types of service interfaces and facilitates installation and flexibleconfiguration. It can provide a solution that is integrated with the TDM microwave, Hybrid microwave,and Packet microwave based on the network requirements. It supports the smooth upgrade from theTDM microwave to the Hybrid microwave, and from the Hybrid microwave to the Packet microwave.The solution can evolve based on the service changes that occur due to radio mobile networkevolution. Thus, this solution can meet the transmission requirements of not only 2G and 3G networks,but also future LTE and 4G networks. RTN 900 V1R1 support pure packet microwave, and RTN 900 V1R2 support TDM microwave andHybrid microwave. HUAWEI TECHNOLOGIES CO., LTD.Huawei ConfidentialPage 6 7.

In the case ofthe Packet microwave, theMUX/DEMUX unit onlymultiplexes/demultiplexes thepacket services and does nottransmit the TDM services to thecross-connect unit or receive theTDM services from the cross-connect unit.

Huawei Confidential Page 65 66. EM6T/EM6F Functions and Features The EM6T/EM6F is an FE/GE interface board, which provides four FE electrical interfaces and two GE interfaces. The EM6T has similar functions to the EM6F. The only difference is as follows: the GE interfaces on the EM6T always function as electrical interfaces whereas the GE interfaces on the EM6F use the SFP modules and therefore can function as two optical or electrical interfaces. The GE electrical interfaces on the EM6F and the EM6T are compatible with the FE electrical interfaces. The EM6T/EM6F accesses, processes, and aggregates four FE signals and two GE signals. In R2 version, the backplane service bus is 1G. EM6T/EM6F support LAG function, support ERPS. EM6T/EM6F support E-Line and E-Lan. EM6T/EM6F supports synchronous Ethernet.
