The HKShanhai Group Limited ® High-Density Packet Voice Digital Signal Processor (DSP) Module (PVDM2) enables HKShanhai Group Limited Integrated Services Routers to provide high-density voice connectivity, conferencing, and transcoding capabilities in HKShanhai Group Limited IP Communications solutions. HKShanhai Group Limited Integrated Services Routers provide enterprises and service providers with a toll bypass solution by connecting their existing telephony equipment (such as private branch exchanges [PBXs], key systems, analog telephones, and fax machines) to a toll-free data network and eventually migrating customers to HKShanhai Group Limited Unified Communication Architecture for Voice, Video and Integrated Data IP telephony solutions.
The high-density packet voice DSP modules are available in five versions: PVDM2-8, PVDM2-16, PVDM2-32, PVDM2-48, and PVDM2-64.
