Configuration Rules for Boards on Resource Shelf/Interface Shelf Differences between the Iub access functions of the interface shelf and the resource shelf:The interface shelf and resource shelf both can provide Iub access.When the Iub access uses the high-speed IP interface (only Ethernet interface is supported currently) , the Iub interface is directly connected to the resource shelf.When the Iub access uses ATM interface or low-speed IP interface, the access is processed by the interface shelf, And the service data are sent to the resource shelf via the switch shelf.Definition of 1000M Interface ShelfThe 1000M Interface Shelf is a type of shelf that is only used for Iub access. Functions of 1000M Interface ShelfProvides ATM access for the Iub interface.Provide IP access (high speed IP interface) for the Iub interface.Note: Low-speed IP access usually refers to that the physical layer uses E1/T1 or the CSTM-1 and the upper layer is IP layer.High-speed IP access usually refers to IP Over Ethernet.

Network Management Networking SchemeSuggestions for Usage:Ordinary users can use the NetNumen network management system.Advanced users can use the OMM network management system.

ZXTR RNC supports multiple IP UTRAN networking modes.Based on the type of the transmission network and the interfaces, the IP UTRAN can adopt the following networking modes:IP UTRAN networking based on the ATM network.IP UTRAN networking based on the SDH network.IP UTRAN networking based on the IP MAN.Hybrid mode, i.e. the split transmission mode.

IP UTRAN Networking Based on SDH NetworkThe RNS equipment is connected to the SDH network via the E1 or channelized STM-1 interface. The SDH network implements transparent transmission. There is no need to add routers and switches.

Usually, the traditional operator has its own SDH network and rich resources, so it is suggested to construct the IP UTRAN network based on the existing SDH network.RNCCSTM-1SDH NetworkIP over E1E1IP over E1Node BIP over E1

ATM UTRAN Transmission ModeATM over E1 can be used in the SDH transmission network.RNCCSTM-1SDH NetworkATM over E1E1ATM over E1Node BATM over E1

IP UTRAN Networking Based on IP MANThe RNC and Node B are directly connected to the MAN via the edge router by GE/FE interface.GE/FEFEFEFEIP MAN

The IP Man can be an IP backbone network that uses high-speed routers as the core equipment, or a MAN using MPLS technology, or a MAN uses the MSTP with embedded RPR technology.In the future, the UTRAN services transmission via IP MAN will become the main IP UTRAN networking mode.RNCNode B

Split Transmission of IP UTRANWhen bearing the traffic between the RNC and NodeB, the Iub interface assigns different physical mediums and bandwidths for the large-traffic NodeB according to the service types.

Data services (e.g. HSDPA) should be transmitted via high-speed interfaces (e.g. FE) in order to reduce the cost of networking, because they have huge peak traffic, large dynamic range of peak-to-average ratio and frequent traffic burst, Signaling, voice, operation & maintenance services should be transmitted via E1/T1 links, because they need to be processed in real time.

ZXWR RNC - Flexible Configuration of Iub Interfaces for TransmissionAs for the transmission mode of ZXWR RNC, the Iub transmission to each Node B can be configured independently.Based on the flexible configuration of the transmission interfaces of ZXWR RNC, it is easy to implement multiple IP UTRAN networking modes.The site with rich TDM transmission resources can choose to transmit all the services via the TDM network.The site with rich IP data network can choose to transmit the services via IP network.If the site has both transmission resources, it can choose to transmit the session services via the TNM network, and the other services via the IP data network.
