12-Port Digital Modem Module (spare)
The Cisco® Digital Modem PVDM Modules are a new set of digital dial modems provided in a DSP form-factor for use in the on-board PVDM slots. They are designed to enhance dial access for the Cisco 2800 and 3800 Series Integrated Services Routers. The Cisco Digital Modem PVDMs provide the Cisco 2800 Series with low-density digital dial access, and they provide the Cisco 3800 Series with a higher-density digital dial platform.
The Cisco 2800 and 3800 Series routers extend Cisco Systems® leadership in multiservice routing, providing customers with high-performance concurrent data, security, voice, dial access, and advanced services-with maximum room for growth. The integrated services routers feature embedded security processing, onboard PVDMs, significant performance and memory enhancements, and new, higher-performance interfaces to meet the needs of the most demanding enterprise branch offices.
The new Cisco Digital Modem Modules are designed in the PVDM form factor for use in the onboard PVDM slots of the Cisco 2800 and 3800 Series integrated services routers. This design reduces the number of network modules required to support a digital modem solution. It allows digital modem support in the Cisco 2800 Series and opens a network module slot on the Cisco 3800 series that can be used for application services modules or for services not available in other form factors. To provide maximum flexibility to meet different branch size requirements, the Cisco Digital Modem PVDM Modules are available in a variety of densities.
