Although the demand for VoIP, 3G and Web 2.0 services continues to increase significantly, the volume of IP voice traffic can vary widely at different points in the network. Network operators and enterprises need the ability to support a wide range of call volumes and the flexibility to increase capacity as demand for IP voice services grows. Ditech's PVP product can support early stage markets and services, in addition to supporting the high-capacity requirements of IP voice services in the core of the network.
"The new low-density PVP chassis has all of the same functionality and performance of the higher-capacity product, but implemented in a way that offers network operators and enterprises more deployment options," said Karl Brown, vice president of marketing at Ditech Networks. "Ditech's new form factor and session capacity ensures that PVP can meet the different network requirements of supporting the growth of IP voice services."
Ditech's PVP product now is available in two platform options: 13RU, 14-slot chassis for up to 16,000 sessions; and 5RU, 6-slot chassis for 1,000-4,000 sessions. Cards in the 6-slot chassis can be redeployed in the 14-slot chassis as the demand for network capacity increases.
Both platforms are available with all three of Ditech's industry-leading applications: Voice Quality Assurance (VQA), Experience Intelligence (EXi), and Dynamic Transcoding. VQA non-intrusively and automatically detects and eliminates problems that degrade voice quality. The application mitigates network-induced impairments, impairments from the caller's environment, and impairments from callers' devices, in real time, on both ends of the call.
EXi non-intrusively measures speech quality in real time, on every call. Information from EXi about signal, noise, echo and frame/packet loss can be input into the ITU G.107 E Model to compute MOS or R-Factor scores much more accurately than solutions that rely on packet loss and delay statistics alone. In addition, EXi statistics can be used directly in pre-configured reports, or integrated with existing network test and measurement systems.
Dynamic Transcoding supports a wide range of compressed and uncompressed codecs, allowing service providers to directly connect diverse codecs without compromising scalability, network performance or call quality. The following codecs are available for both platform options: G.711 (I 1/4-law, A-law, with full support for Appendix II and intelligent packet restoration,) G.723.1, G.723.1a, G.726, G.729, G.729a, G.729b, G.729ab and iLBC.
