Products and Application ScenariosOverviewThe U2000 provides various OM solutions for telecom operators to meet the requirements of network deployment, network monitoring, network adjustment, and service management. Telecom operators can select proper U2000 systems as required. OM SolutionsLow-Cost SolutionThe M2000 provides a low-cost solution, which uses the single-server system based on the IBM platform to manage LTE/EPC network devices for operators. This solution meets users' demands for routine network OM operations. In addition, it helps operators or users to reduce their purchase costs. In the low-cost solution, the single-server system based on the IBM / Huawei platform uses IBM/Huawei PC server and does not need disk arrays.Comprehensive System Security SolutionBased on the features of the OM plane, the OSS security solution is designed to meet the requirements on the following security layers:Network security: Secure networking technologies, such as security domain division, firewall, secure remote maintenance, and intrusion detection, to protect the OSS network.Platform security: Security measures, such as system hardening, security patching, and antivirus protection, are implemented to promote the security level of the operating system OS and therefore provide a secure and reliable platform for OSS service applications.Application security: Security policies, such as transmission security, user management, session management, log management, and security alarm, are implemented to protect the security of specific applications.Network Time Synchronization SolutionThe U2000 supports the Network Time Protocol (NTP)/Simple Network Time Protocol (SNTP) to synchronize its time with NEs on the entire network. The clock source and NTP server are provided by the telecom operator, and the U2000 server functions as the NTP client or intermediate NTP server. When functioning as an intermediate NTP server, the U2000 can synchronize time with the upper-layer NTP server and provide a clock source that managed NEs can synchronize with.A dedicated clock server is provided, along with two NTP service channels working in active/standby mode. The clock source server can be deployed as the top NTP server, or as a intermediate NTP server.Network ManagementThis section describes the main functions of the U2000 network management.

Technical SpecificationsOverviewThis chapter describes the following system specifications:Management capabilityReliability specificationsCompliant safety standardsEMC specificationsEnvironmental requirementsManagement CapabilityThe management capability of the U2000 is calculated according to equivalent NEs, and the NMS server is configured according to the number of equivalent NEs.Table 6-1 describes the capability of the U2000. The IBM/HUAWEI PC server uses the SUSE Linux10 operating system and Sybase15.5 database. NE management capability of the U2000 (except SLS system)Hardware PlatformManagement Capability (Number of Equivalent NEs)

2 CPU IBM x3650 M450

4 CPU RH5885H V380

The number of equivalent NEs is determined by the following factors: Physical NE type and version: Different NE types and versions use different amounts of U2000 resources. As a result, the number of equivalent NEs converted varies according to the NE type.Number of measurement counters: KPI or all counters can be set to measure an NE's performance. In either scenario, the required amount of U2000 hardware resources is different. Therefore, the number of measurement counters has an impact on the equivalent NE conversion.Performance statistical period: Each NE reports performance data to the U2000 at certain intervals. Processing data reported every 60 minutes requires different amount of U2000 hardware resources from that reported every 15 minutes.The number of equivalent NEs for the same type of NEs varies according to performance measurement requirements of users. For details, see the table of calculating equivalent NEs in iManager U2000 V200R014 Configuration Principles. You can contact Huawei technical support to obtain this document. You can ask Huawei engineers to analyze and calculate the number of equivalent NEs for the measurement unavailable in the table.
