ZXUR 9000 Board Classification

Switching Board

Processing Board

Interface Board

Switching board deals with the switching in control plane (BASE) and media plane (FABRIC). Besides the intra-shelf switching, it also provides switching channels for all inter-shelf communication.

Processing board handles the protocol processing in control plane and user plane, and is responsible for the overall processing and control in terms of O&M.

Interface board offers access of STM-1, E1/T1, CSTM-1 via interfaces including A, Abis, Gb, Iu, Iub and Iur to meet various requirements of networking.

ZXUR 9000 Configuration Principle and Highlight

3-layer shelf, main shelf is preferred for the lower layer.

Every shelf is composed of front and rear plug-in shelf, with 14 board slots for each.

UMP is fixed in No. 5-8 slot in front plug-in shelf; EGBS and EGFS fixed in No. 19-22 slots in

rear plug-in shelf; interface board is configured in rear plug-in shelf, while USP and ETCB in

front plug-in shelf, and no slot limitation for these boards.

The configuration of processing boards depends on traffic model and have several

limitations for each board need to be considered and calculated.

23

Almost non-limitation on slot design, easy to expand. Flexible and easy configuration for

conversion between GSM and UMTS modes.

Any idle slot is available, high shelf utilization.

Processing Board Capability

For UMTS, the PS index of RUP is based on subscribed MBR 4M, HS896/128 with 2K signaling (UL+DL). And for the different average rate of PS active user, the capacity of RUP is changed. The relation between VACT and TRUP is following the table below:

In which:

VACT : The average rate of PS active user

TRUP: The throughput capacity of RUP

The CS index of RUP is based on VAF is 0.5. With different VAF, the non encrypted CS capacity of RUP is 9000*0.5/VAF, and the range of VAF is 0.5-1.
