ZXUR 9000, as a new generation radio network controller, uses all IP hardware structure, modularized design and distributed idea, providing network control functionality under GSM, UMTS or GU dual mode. It has extremely large processing capability, with high integration and intelligent design, which effectively improve the utilization rate of transmission and radio resources, simplify the whole network maintenance, cut down CAPEX and make the maintenance more convenient.

Switch board provides large capacity and non-blocking switch function for system control management, communication between service processing boards and traffic connection among multiple access units. Switch board includes: EGBS (Enhanced GE Base Switch board, GSM/UMTS): EGBS is the switch board of control plane, and provides intra-shelf and inter-shelf control plane switch channel. EGBS in master shelf is in charge of the control plane channel between two slave shelves and one master shelf. EGFS (Enhanced GE Fabric Switch board, GSM/UMTS): EGFS is the switch board of user plane, and provides intra-shelf and inter-shelf user plane switch channel. EGFS in master shelf is in charge of the user plane channel between two slave shelves and one master shelf. EGFS in master shelf also works as a clock board, which is responsible for the clock supply and external synchronization

Processing board processes control plane signaling and user plane information, including voice, data, stream and transcoding. Processing board includes: UMP (Universal Management Process board, GSM/UMTS): UMP realizes operation and maintenance function, and provides global management processing. USP (Universal Service Process board, GSM/UMTS): USP realizes service processing function, including the GSM/UMTS control plane and user plane protocol stack processing. From the viewpoint of logic functionality, USP board is divided into three parts: CU (Common Unit), DUc (Dedicate Unit control plane) and DUm (Dedicate Unit media plane). Both CU and DUc are responsible for control plane processing. CU is used for common signaling processing among cells while DUc is dedicated for user signaling processing irrelative with cells. DUm is used for user plane processing. ETCB (Enhanced Trans Coder Board, GSM): ETCB realizes transcoding and adaptation functionality

Interface board provides access implementation for A, Abis, Ater, Gb, Iu, Iub, Iur interfaces. Different interface boards are configured so as to achieve customized transmission solution. Interface board includes: EDTA (Enhanced Digital Trunk board ATM version, UMTS):EDTA realizes ATM over E1/T1 access function. ESDTA (Enhanced SDH Digital Trunk board ATM version, UMTS): ESDTA realizes ATM over CSTM-1 access function. EDTI (Enhanced Digital Trunk board IP version, GSM/UMTS): EDTI realizes IP over E1/T1 access function. ESDTI (Enhanced SDH Digital Trunk board IP version, GSM/UMTS): ESDTI realizes IP over CSTM-1 access function. EDTT (Enhanced Digital Trunk board TDM version, GSM): EDTT realizes TDM over E1/T1 access function. ESDTT (Enhanced SDH Digital Trunk board TDM version, GSM): ESDTT realizes TDM over CSTM-1 access function, which can be used in A interface only. EGPB (Enhanced GE Process Board, GSM/UMTS): EGPB realizes GE/FE access function. EAPB (Enhanced ATM Process Board, UMTS): EAPB realizes ATM over STM-1 access function. ESDTG (Enhanced SDH Digital Trunk board GSM version, GSM ) ESDTG realizes TDM over CSTM-1 access function. EXGB1b (Enhanced XGE Process Board 1b, GSM/UMTS) EXGB1b realizes 10GE access function
