Solver UMTS Iu-PS generator is a high performing test tool to load and stress the Packet Switched Core Network using ATM STM-1 interfaces or Ethernet for IP to connect to the SUT (System Under Test).

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

Solver IuPS generator has the capability to load and stress the SUT with both control plane signalling, establishment and release of GTP tunnels and IP application payload.

The Solver interface solution has a large on-board memory capacity and powerful processing cabability. The on-board memory is for the storage of IP application payload data that can be used in the different scenarios that are set up within Solver.
