Solver UMTS IuCS generator is a high performing test tool to load and stress the Circuit Switched Core Network using an ATM STM-1/OC3 interface for ATM or Ethernet for IP to connect to the SUT, (System Under Test).

The Solver ATM test solution can scale from a minimum of 4 ATM ports up to 24 ports.

Solver can load and stress the SUT with both control plane signalling, AMR coded voice traffic and 64 kbps data.

The Solver interface solution has a large on-board memory capacity and powerful processing capability. The on-board memory is for the storage of speech samples that can be used in the different call scenarios that are set up within Solver.

With Solver Iu-CS generator and the add-on PESQ application, speech quality measurements can be done using specified voice samples.
