Spectra2 - Core Network Test

Signaling and Media Test solutions for the lab and the field.

Proliferation of smart phones, tablets and multimedia applications (Video, Voice and Data) are demanding the faster migration to all-IP networks while carriers are still trying to leverage on their legacy infrastructure. The coexistence of legacy and emerging networks along with the convergence between fixed and mobile networks creates challenging core network test conditions for operators and manufacturers.

IMS is a service rich environment with video, presence, voice, and vertical features, but legacy services based on PSTN still remain. Carriers must ensure that their new IMS IP services work and that their legacy services can be integrated with their new IP infrastructure. Core network test troubleshooting has become more challenging due to the flexibility introduced by text-based IP protocols. IMS and LTE drive new applications, media policies, charging plans and mobility. So core network test tools must be able to validate SIP call control along with Diameter based location, policy, charging and services management. Legacy architecture will remain in place for years to come. This means that end-to-end testing of call control and media Quality of Service (QoS) from time domain multiplexing (TDM) to TDM, TDM to IP, and TDM to IP to TDM must be validated to ensure service quality. With the rapid expansion of network infrastructure and services, operators and manufacturers are facing challenges in field troubleshooting with the limited capabilities of the test tools they currently possess.

Spectra2productsNetscout Spectra2 Core Network Test solution integrates functional test, load/stress testing, conformance testing, interoperability testing, Quality of Service measurement and monitoring for emerging technologies (IMS, NGN and FMC), legacy technologies (PSTN/SS7 and ISDN) and VoIP (SIP and H.323) into a single platform. Spectra2 Core Network Test solution is one of the only tools on the market that can perform TDM and IP testing in a single chassis with a single user interface. Spectra2 Core Network Test solution enables end-to-end Quality of Service and call control validation in a single platform of gateways converting ISUP to SIP or SIP-I, enterprise PBXs using ISDN to SIP Trunking, and TDM media conversion to and from IP.

  • The Spectra2|SE² software only test solution provides high capacity IP signaling and media testing in the field. This laptop-based functional, load, and monitoring solution enables cross domain IP testing with media. Call scenarios from the field can be captured and imported directly to a Spectra2 server in the lab. This approach integrates field experience into the lab to avoid getting burned by the same problem twice.

  • The Spectra2 3U is the state-of-the-art lab test platform containing newly designed purpose built hardware, optimized for the telecommunications test and diagnostics.Spectra2 software has support for broad range of IP and TDM protocols. With the new performance threshold set by 3U, the integrated solution offers an ideal platform for testing in mixed protocol environments. Spectra2 SIP and Diameter solutions can validate SIP based call control, SIP trunking, and SIP services. Each of these services normally involves Diameter transactions for AAA, Services, Policy Control, and Charging. Spectra2 simulates a variety of IMS nodes from your CSCF, to HSS, to PDF, OCS and LTE EPC nodes like MME, to PCRF and PCEF. Spectra2 Core Network Test solution simulates and validates new services prior to investing in platforms or software..

  • The Spectra2 XL3 is your bulwark against signaling storms. A robust testing platform for validating both signaling and media performance, the XL3 covers the three most important dimensions of LTE network performance testing: Diameter transactions per second (TPS), Media/RTP simultaneous calls, and cumulative media quality of experience (QoE). With the comprehensive results generated from your testing you’ll be able to achieve the best possible performance from your network and deliver your services with confidence.
