ZXUR 9000 subrack (Front, Rear, Side view)
on capacity requirement, configured from 1-2.
Components of each subrack (from top to
bottom) ：

19 inch standard subrack
 FAN unit (3 FANs, 2 for front subrack heat

Front and rear plug-in subrack for each subracks, each
dissipation, 1 for rear subrack heat dissipation)
 Plug-in boards (front board 8U, rear board 9U)
 Power unit (each subrack configure 2)
have 14 slots

Processing boards and O&M boards in front shelves ,
designed with ATCA standard board

Interface boards and switching boards in rear shelves
Distributed design, resource pool for service handling ensure high
reliability, strong processing capability with high efficiency.

Processing Board
Interface Board
© ZTE Corporation. All rights reserved
Switching board deals with the switching in control
plane (BASE) and media plane (FABRIC). Besides the
intra-subrack switching, it also provides switching
channels for all inter-subrack 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, FE GE(10GE) via interfaces including A,
Abis, Gb, Iu, Iub and Iur to meet various
requirements of networking.

Position and Function of Processing Board

UMP1c (Universal Management Process board 1c )

It provides global management processing and maintenance function.

It implements NE operation and maintenance functions. It is connected to the
EMS through the GE interface on the rear board EGBS2a.

The slot number for NE operation and maintenance functions is 5-6, and for
OMP is 7-8 in master subrack.

USP2a (Universal Service Processing Board 2a )

USP2a fulfills service processing function, including the GSM/UMTS control
plane and user plane protocol stack processing.

Slot numbers from 1 to 4 and from 9 to 14 (for master subrack, 1 to 14 for
slave shelves)

13
Position and Function of Processing Board

ETCB (Enhanced Trans Coder Board):

ETCB converts the voice codes of the radio interface to PSTN A-law PCM
voice codes, and vice versa. In addition, it adapts the rates (including the
rates of data services) between these two types of codes.

Apply to GSM only

Slot numbers from 1 to 4 and from 9 to 14 (for master subrack, 1 to 14 for
slave shelves)

GE interfaces to all service slots and rear switching slots, and inter-subrack
cascade GE interface. The slot number for EGBS2a is 19-20.

EGBS2a in master subrack is also in charge of the control plane channel
between slave shelves and master subrack.


The EGBS2a board only supports the BETC/3 backplane
EXFS1a( Enhanced XGE Fabric Switch board 1a ):

EXFS1a has a built-in clock module. The slot number for EXFS1a is 21-22.

Implements inter-subrack media plane switching function, and inter-subrack
cascade 40 GE interfaces.

ECDM Board
According to the DIP switch described below,
check whether the DIP switch on every subrack is
in the correct status and whether it is consistent
with the planned subrack No.
ECDM records shelf configuration information (such as the shelf serial number ),
system capacity information (such as the number of slots, the power consumption of
each slot, and the topology structure), and other customized information

redundancy design by platform and
high reliability. No single point fault,
online software download
supported, loading and being
activated in remote.
Abundant interfaces, flexible
networking, IP protocol stack and
diverse physical interfaces like FE
and GE supported, flexibly
responding to transmission changes.
Complete transmission and processing
resources sharing between GSM and
UMTS, unified RRM realizing users
flexible access to Gu network,
balancing loads, maximally utilizing
network resources. Smooth evolution
from 2G to 3G by software upgrading.
All-IP structure meets the requirement
of network evolution. Compared with
TDM/ATM platform, IP switch
management features convenient
maintenance, simple configuration,
flexible expansion, higher delivery
efficiency and more flexible delivery
mechanism.
Simple configuration, convenient
maintenance. Few board types,
including processing, interface and
switching boards, making
configuration simpler and
expansion easier, also reducing
spare parts types, cutting down
maintenance cost.
