Cisco Digital Modem Modules for Cisco 2800, 2900, 3800, and 3900
Series
Series
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,
2900, 3800, and 3900 Series Integrated Services Routers. The Cisco Digital Modem PVDMs provide the
Cisco 2800, 2900 Series with low-density digital dial access, and they provide the Cisco 3800, 39000
Series with a higher-density digital dial platform.
Overview
The Cisco 2800, 2900, 3800 and 3900 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, 2900, 3800 and 3900 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, 2900
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, listed in Table 1.
Figure 1 shows the digital modem modules.
