Digital Modem Network Modules
for the Cisco 3600 Platform
Introduction
The Cisco 3600 Series is a family of modular, multifunction access
1. Note: These digital modem network modules must operate in conjunction with a
TI/EI/PRI/BRI network module. For details on supported PRI network modules, see
the “Technical Specifications” section.
routers for medium and large-sized offices and smaller Internet
Service Providers. With over 70 modular interface options, the Cisco
3600 family provides solutions for voice/data integration, virtual
private networks (VPNs) dial access, and multiprotocol data routing.
Using Cisco’s Voice/Fax network modules, the Cisco 3600 Series
allows customers to consolidate voice, fax, and data traffic on a
single network infrastructure. The high-performance, modular
architecture of the Cisco 3600 Series protects customers’ investment
in network technology and integrates the functions of several devices
into a single, manageable solution.
Now, with this announcement of the new digital modem
network modules, the Cisco 3600 expands its role as a multifunction,
branch/enterprise orientated platform that, supports voice over data,
dial access and LAN-to-LAN or routing in one modular platform,
making it an ideal solution for the “power branch” environment.
