CISCO 2600/3700 48 CH PKT VOICE/FAX DSP MOD-SPR

The High-Density Packet Voice digital signal processor (DSP) Module (PVDM2) enables Cisco multiservice access routers to provide high-density voice connectivity, conferencing, and transcoding capabilities in Cisco IP Communications solutions. Cisco multiservice access 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 migrate customers to Cisco AVVID (Architecture for Voice, Video and Integrated Data) IP telephony solutions. The high-density packet voice DSP module is available in five versions: PVDM2-8, PVDM2-16, PVDM2-32, PVDM2-48, and PVDM2-64. PVDM2 will be used across a series of Cisco multiservice access routers and high-density voice network modules. This allows users to distribute or reuse DSP resources among the routers or network modules as needed. Field-upgradable capability enables users to easily scale their voice deployment. In addition, each DSP on the PVDM2 provides four times the processing power and higher memory than that on the existing PVDM. The high performance of PVDM2 supports future growth. PVDM2 provides high call density per DSP and flexibility on the channel allocation. The maximized support of uncompressed G.711 voice calls optimizes the DSP utilization for the solutions, mainly based on G.711 codecs such as IP telephony, in a LAN where
