4. System Requirements

5. Functional Overview  Cross platform FreeBSD, Linux, Solaris  Multiple & Concurrent Administrators  JDBC Familiar Database like PostgreSQL, MySQL, MS SQL and Oracle etc  Network Topology Auto Discovery and Generation  Network Devices Periodically Polling  In-time Devices Status Graphically Presentation  Multiple Devices Batch Configuration  Device Trap Messages Addable and Customizable  Multiple Trap/Alarm Notifications Email, Sound and SMS (by email)  Device Panel Simulation

6. Technical Specification Supported Platforms FreeBSD, Linux, Solaris Choice of Clients Java Application client, Database PostgreSQL, MySQL, MS SQL, Oracle,…etc JDBC Familiar Databases JRE/JDK1.6.0 Language support JDK 1.6 Internationalization API StandardVersion(s) Key Benefits XML1.0 XML facilitates an efficient data interchange between components of an application and between applications by providing an extensible mechanism to describe the meaning and hierarchical structure of data. JDBC1.1 & 2.0 JDBC provides database vendor and technology independent (RDBMS, ODBMS etc.) and platform neutral API's to access data from multi-tier and client-server applications. Java RMI 1.0 RMI facilitates distributed computing so that distributed applications with high scalability and performance goals can be built. SNMPv1, v2c, v3 The Simple Network Management Protocol (SNMP) is the most widely used management protocol, that defines the communication mechanism between the managed entities and the management station, the information model and the security and access control mechanisms for sharing management information.

D-JEMS vs. D-EMS(WebNMS) Items D-EMS (WebNMS) + D-JEMS ArchitectureMulti-Tiers2-Tiers Clients Java Application client, Java Applet client, Web (HTML) client, Java Web Start Client Java Application client, Web (HTML) client Northbound TL1, SNMP, CORBA, XML, and etc SNMP & others * (Depend on Customer requirement) Southbound TL1, SNMP, CLI, CORBA, XML SNMP & others * (Depend on Customer requirement) + The D-EMS(WebNMS) is accepted by CHT 2009 VDSL2 Tender for management. It uses the same platform as the AMS (ASKEY’s EMS for DAS-3 & DAS-4 series IPDSLAM) * The Green items will be supported in the future.
