SOLVER for ISUP is a high-performance load and stress test tool for ISUP based telecommunication networks. SOLVER provides the ability to simulate ISUP calls with a large number of simulated subscribers providing load to switches.

SOLVER makes it possible to generate and terminate calls, test network indicators and provide real-time statistics on traffic progress. Various traffic patterns are easily created to run simultaneously or in sequence.

The new SOLVER SDH hardware architecture provides a unique ability to test channelized STM-1/SDH and SONET circuits with a high degree of calls. Powerful resources for voice quality testing, such as PESQ, are available through a large, on-board memory capacity.

Any DS0 channel can be configured to carry signalling, simple payload or user-definable payload for PESQ testing. A large number of user-definable payload samples can be recorded, transmitted, received and stored on each STM-1.
Stored samples can be sent through a dedicated 1GB Ethernet interface to a separate server for PESQ analysis and scoring.

The architecture is built on a carrier-class CompactPCI form factor. It is a fully scalable solution from zero to full payload channel utilization.
