DeriveIt TL1-based Network Simulator, in our line of network element simulator products for TL1 based network elements for development and testing of Network Management Systems.

General features:
• Can simulate multiple NE (Network Element) types simultaneously.
• Can simulate over 1000 NEs simultaneously.
• Cost savings (i.e. each engineer has a NE on their desk).
• Enables NMS testing prior to hardware delivery.
• Software Developer Independance (i.e. each engineer can provision their NEs the way they want to, without worrying about someone modifying their configuration.)
• Supports multiple types of communication protocols, i.e. TCP/IP, OSI, TELNET, CID
• Runs on Windows 98/2000/NT/XP
• Faster than a real NE.
• Can generate alarm bursts of 2000 alarms/second
• Helps verify NMS limitations, such as the maximum number of NEs supported.
• Alarm Generation- can generate any and all alarm messages the NE can send.

Supports the following alarm generation modes:
• Single shot alarm generation (also with clear message)
• Periodic alarm generation (also with clear message)
• Burst alarm generation
• Save to alarm log. Easy to group/edit/select alarms for specific test cases.

Customized Command/Response Definition:
This feature of the NE Simulator allows the user to customize the response to a command received. This feature is quite helpful when trying to test certain cases where a command is denied with a specific error code. It basically allows the user to test interactions between the NE controller/network element, which the NE Simulator is unable to simulate, such as deny responses with specific error codes.

Import Dump Files Utility:
This new feature the allows the user to take any output file from a TL1-based NE and convert it to Deriveit’s NE Simulator ready files, e.g. Response files (*.re1) to be used as responses for TL1 commands, or Alarm files (*.a1) to be used as alarms, events, PM reports or any other automatic messages.

Supports Multiple NE User Login Sessions per NE:
The NE Simulator’s business purpose is to reduce the cost and expedite the deployment of network management systems according to the individual needs of the customer. This is accomplished by reducing the cost in equipment (i.e., reduced NE hardware costs) , the convenience (i.e., each engineer can have the NE Simulator on his desk), and the versatility of NE Simulator (in being able to tailor it according to each individual developer's needs).

Playback option
Allows you to take any session log (i.e.- from the equipment or from the NE Simulator Capture Screen), and duplicates that session with the NE Simulator. The NE Simulator will simulate the EXACT scenario based on what is provided from the log file. The EMS will play the role of manager, and the NE Simulator will play the role of agent, playing the exact same role as they played in the log. The key is trying to reproduce the sequence of interactions between a manager (EMS) and a network element. Uses for the Playback feature include regression testing, as well as a way to troubleshoot incorrect EMS behaviors (Recreating certain scenarios in the field vs. lab network configurations).
