SOLVER for ISUP

Solver for ISUP provides load and stress to ISUP based telecommunication networks. Solver provides the ability to simulate ISUP calls with a large number of simulated subscribers providing load to switches.

Solver ISUP can simulate a Public Switched Telephone Network (PSTN) with hundreds of thousands connected subscribers providing load to the Core Network (CN). A number of different traffic scenarios and various call settings can be made in order to achieve as close to real-life traffic conditions as possible.

The interface used for the Polystar Solver ISUP load generator is channelised E1/T1 over STM-1/OC3 (SDH).

Protocol Conformance ISUP interface

Control plane:

• ISUP (ITU-T Q.76x / ANSI T1.113-2000)
• MTP3 (ITU-T Q.704 / ANSI T1.111-2001)
• MTP2 (ITU-T Q.703 / ANSI T1.111-2001)

User plane:

• PCM coded G.711 A-law and u-law

• Originate and terminate calls with Control Plane signaling and User Plane (payload).
• Provides fine-grain control over call set-up rates and parameters.
• Displays call activity and completion statistics such as setups, releases and active calls online.
• Generates high traffic load towards the Core Network.

PESQ

Verify speech quality by using PESQ measurements on several simultaneous calls, while at the same time generating heavy background traffic.

• Data & Fax calls for ISUP, A and Ater.
