Advanced Call Generator

Advanced Call Generator for Mobile Network Testing

Our Advanced Call Generator (ACG) is a test call generator tool used for mobile network testing. This model of ACG’s is capable of testing both 4G, VoLTE and 3G. The ACG is designed for use with our Osprey™ Revenue Assurance solution. It can be used to generate independent test events such as Voice, Messaging and Data services (including circuit switch fall-back).

The ACG records and measures exactly what the subscriber experiences from end to end. The data recorded by an ACG is primarily used to identify the successes and failings of the operators metering and billing platforms, however it can also be used to determine network service performance.

The unique data set provided by an ACG delivers reports on many crucial KPIs. Such as data speed, throttling, metering and bundle depletion accuracy. In the case of change assurance, ACG units can be used to verify the billing systems are calibrated as expected and Voice, Messaging and Data services are being billed as required. 

There are many applications of the ACG and we recommend that you Talk To Us so that the right tools can be provided for your test solution.

SIM Server (Multiplexer)

Our SIM Server provides a convenient centralised SIM management option to our already established Osprey™ Test Call Generation solution. Integrating a SIM server reduces the operational overheads of managing physical SIMs inside TCGs located in various geographical locations. This solution allows your test SIMs to travel anywhere in the world that a TCG has been installed.

Efficient, Centralised SIM Management

  • SIMs are securely held at your local site for easy access
  • SIMs are automatically detected, minimising manual configuration
  • SIM boards are hot-swappable, minimising system downtime
  • Centralised SIMs are placed remotely into your test call generators

Increased Capacity and Scalability

  • Up to 400 SIMs can be deployed in a single SIM Server
  • Each SIM Server supports 200+ concurrent connections for 100+mobile calls where TCG volume allows.

Maximised Test Scenario Flexibility

  • Any test SIM can call any other test MSISDN
  • Faster deployment to test new promotions
  • More space for testing legacy tariffs and provisions if required
  • Optimises geographical coverage for roaming/interconnect
  • Compatible with 5G/4G/3G/2G SIMs

Micro Event Generator for Mobile Network Testing

Our Micro Event Generator (MEG) is a small form factor test event generator, designed to work with our Merlin™ Service Assurance tool. The MEG Unit performs end to end testing on a CSP’s Voice, Messaging and Data services, ensuring services are available and of a suitable quality. Its aesthetic design and simplicity to install allow the MEG unit to be deployed in public areas or be issued to end users.

Our MEG units can be used to identify issues, confirm customer reported issues, refine issue descriptions and provide accurate details of issue symptoms. In the case of change management and network fixes, MEG units can be used to verify the network is calibrated as expected and Voice, Messaging and Data services are working as required.
