Version Management
With this function, administrator can view versions of the all software and hardware running at the foreground. The hardware version includes the BOOT version number and its generation time. The software version includes the software version number, download time and its current running state.
32 © 2023ZTE CORPORATION. All rights reserved. ZTE Confidential Proprietary
ZXSDR BS8700 Product Description
The background provides a software downloading system for software download/upgrade at the foreground. Before download/upgrade, warehousing processing is required. The warehousing process will copy the version files to the server and register to the server.
Software versions existing in the base stations can be activated with or without software tests.
Alarm Management
The alarm management system monitors running states of the base stations, dynamically displays the rack structure of the foreground module and collects abnormal information of the boards, links, database and server in real time. These functions make it convenient to analyze, address the problems, maintain and repair.
Information collected by the alarm management system includes notification, alarm and alarm recovery.
The alarm management system synchronizes alarms, reports historical alarms and current alarms, and sets and queries alarm shielding.
Configuration Management
Configuration management implements functions of equipment configuration and radio configuration.
Log Management
NetNumen M31 system provides the log management function. Any operation performed by operator will be recorded automatically. Thus, the operation maintenance administrator can query historical operation records. Log records are saved in the NM database server.
Security Management
Security management is implemented through user management and user group management. The user management includes the management for user name, password and user groups which the user belongs to. The user group management includes the management of user group name and authority information (indicating authorities the user group has).
Performance Management
Performance management is to measure, report and provide performances statistic of base stations.
Diagnosis and Test

Single BPC supports 6 CSs, uplink 192 CEs and downlink 192 CEs
In typical configuration, the BS8700 baseband unit provides 4 baseband processing board slots. 1 more BP board can be available if only one FS board is configured.
7.2 Radio Unit Configuration Principles
On different frequencies and software configurations, BS8700 can be configured as various GSM/UMTS base stations:
In GSM single mode, R8860E supports 6 TRXs. One R8882 supports totally 4*2 TRXs.
In UMTS single mode, R8840 and R8860E supports 4 carriers, R8880A supports 4*2 carriers, R8882 supports 2*2 carriers, and R8890 can support 3*3 carriers.
If GSM/UMTS are in the dual mode, single R8860E can support 1 UMTS Carriers + 4 GSM TRXs or 2 UMTS carriers + 2 GSM TRXs at maximum; single R8882 can support (4G+1U)*2 or (2G+2U)*2.
7.3 GSM Single Mode Configuration Principles
R8860E or R8882 is configured for GSM single mode, which is based on multi-carrier technology.

7.5.2 GSM 900M/1800M and UMTS 2100M Dual-Mode Network in Different Spectrums
R8840/R8880A and R8860E/R8882 are configured simultaneously in this scenario, R8840 or R8880A is used for UMTS 2100M while R8860E/R8882 is used for GSM mode.
Wideband combiner is required in the mode of co-feeder-line and co-antenna.
