ONU Validation & Regression Testing

  • No commercial chipset or OMCI stack
  • BBF.247 & TR-255 javascript library packages
  • Decoding according to ITU G.984.x (G.PON), G.987.x (XG-PON), G.9807.x (XGS-PON), G.989.x (NG-PON2),  G.988 (OMCI)
  • Generate and Receive every PLOAM messages
  • Generation and Reception of OMCI Create/Get/Set/Delete requests
  • 3rd party Traffic Generator Integration
  • Full Automation
  • Official Test tool for ONU certification
  • Can also be used as GPON Analyser

MT2 eOLT

The eOLT is a GPON OLT Emulator based on a high performance FPGA-based optical processing unit, and controlled through a dedicated GUI software client installed on a PC. eOLT is the official BBF.247 certification testbed, with test scripts avaiable for both BBF.247 & TR-255, it is also possible to adapt existing scripts or to create new scripts through the Javascript language.

Neutrality

The eOLT emulator uses a neutral independent architecture and OMCI stack, it is independent of any chipset. It incorporates ONU bring-up management (automated and manual), and allows real time traffic forwarding in both directions.

Scripting

Scripting is a key feature of the eOLT with scripting being possible through the javascript language, existing test scripts can be modified or new scripts can be created to target specific operational needs. High level management, OMCI and automation primitives are provided (with their source code and API documentation) to facilitate script writing and test management.

Flexibility

An adaptation layer is provided, to control a traffic generator: this adaptation layer may be used as a template to create adaptation layers for other traffic generators.

Open Architecture

The eOLT G-PON is based on the same powerful Client-Server architecture as the NIVA GPON analyser. The Client GUI offers a CLI and Script management interface, the GUI can also remote control a traffic generator.

Automation

Advanced automation is possible providing time-saving capabilities, for example different scripts can be executed one after the other for different ONU's.

FAQS

Q:
What can you do with an OLT Emulator
A:

With the eOLT emulator, you can easily test the ONUs behavior and its conformance by:

  • Performing your own tests using the scripting language, run a pre-configured conformance test script such as the BBF.247 G-PON ONU certification program
  • Running existng test libraries like the BBF.247 G-PON ONU certification program
  • Checking step by step conformance process such as activation stages one by one, OMCI sequences etc.
  • Accessing protocol data such as PLOAM/OMCI messages exchanges, GEM Ports and monitoring the bandwidth allocated to the ONUs.

Q:
Why should you use an OLT Emulator
A:

OLT emulators are used to:

  • Test and validate ONTs/ONUs. An OLT emulator is the perfect tool to test vendors’ equipment during a network deployment or the equipment development itself.
  • Prepare and Pass the BBF.247 certification program allowing users to prepare equipment for certifcation and test their own equipment before the certification process.
  • Highlight Interoperability issues in a multiple vendor scheme, and resolve communication issues between OLT's and ONU's.
  • Diagnose and refurbish faulty ONUs using pre-exisiting libraries users are able to easily test faulty ONU's returned by customers.

Q:
Can the eOLT emulate an OLT with more than one ONT connected.
A:

The eOLT emulator can work with one or several ONUs at once and is able to mimic the working of any PON OLT in the field. eOLT offers a capture & replay feature which allows to reproduce a behavior observed on the field in your lab.
